Nitrogen is the most widely-used fertilizer in the world, and it makes sense to get the most out of it.RDX Technology from Redox includes the patented and potent biostimulant RDX-N®, along with newly-released RDX-Flex™.  These two products work well throughout the season to get more nitrogen where it counts. RDX technology can lower liquid nitrogen applications by 50% without loss of yield or quality."You're getting more nitrogen energy utilization moving through that plant," said Redox West VP Jared Sannar. "I don't want to leave out this reduced stress. You measure that through redox potential. There's other ways to measure that where you're reducing after treatment, whether soil applied, research shows and our field experiences, whether it's soil applied or foliar, you are reducing the stress after an application. And that has carry. We've seen this out to 30, 40 days in some crops."Find out more from Sannar and Redox Agronomist A.J.

Nitrogen makes up the majority of all fertilizer used. Whether good markets or bad, it makes sense to use it wisely.  Southern Idaho grower Shey Taylor is using new technology to cut his synthetic nitrogen use in half, yet maintain or enhance yield and quality this season. Driving this positive change is RDX-N®, a patented and potent biostimulant that puts more nitrogen to work where it counts- inside the plant."We could see just from 140 acres last year of applying RDX-N that the bottom line was going to be way higher,"Taylor said. "Applying RDX-N saved us $60 an acre, which is especially helpful in the spring, when we have many expenses out."Taylor said cost saving is crucial to his bottom line, especially consider so many of his inputs have increased in price. Find out more about RDX-N at https: RedoxGrows.com/product/rdx-n/.

Welcome to The Turf Zone podcast. This episode features the article “Managing Poa annua on Ultradwarf Bermudagrass Greens” written by Chris Neff, Senior Agronomist, East Region and Jim Brosnan, Ph.D., Professor, University of Tennessee. Poa annua is one of the most persistent and disruptive weeds in ultradwarf bermudagrass greens. In this article, we explain why Poa annua thrives, how it impacts putting green playability and performance, and the cultural, chemical and routine maintenance practices that can help keep it under control. Success depends not on a single herbicide, but on an integrated management program that promotes healthy bermudagrass year-round. Key Takeaways: Poa annua is problematic in ultradwarf bermudagrass putting greens because the plant characteristics and timing of active growth for the two grasses are so different. Fully eradicating Poa annua from ultradwarf greens is very challenging, so the goal for most courses is to minimize its presence and impact on playability. Pre and postemergence herbicides are part of successful control, but resistance is an issue and herbicides alone cannot solve Poa annua problems. Cultural practices and growing environments that favor dense and healthy ultradwarf greens are a critical part of any Poa annua control strategy. Poa annua remains one of the most persistent and disruptive weeds in ultradwarf bermudagrass putting greens, particularly throughout the Southeast. From a consulting perspective, it is less a question of whether Poa annua will be an issue and more a matter of how well it is managed within the system. Its biological advantages, rapid germination, prolific seed production and adaptability to low mowing heights make it uniquely suited to exploit weaknesses in bermudagrass stands, especially during seasonal transitions. The primary issue Poa annua presents is inconsistency. Bermudagrass and Poa annua differ significantly in growth habit, color, leaf texture and seasonal performance. These differences manifest most noticeably on the putting surface, where uniformity is paramount. Poa annua tends to produce a lighter green color and a more upright growth habit, creating a mottled appearance that is often unacceptable to golfers. The differences in growth habit and timing of optimal growth also lead to bumpy surfaces, especially when Poa annua is growing actively in shoulder seasons while bermudagrass is growing slowly or is fully dormant. Early spring can be especially problematic in the Southeast because conditions are ideal for Poa annua while bermudagrass is often worn down by winter play. Aggressive Poa annua seedhead production, particularly in late winter and spring, adds to the variability in ball roll. Even under intensive management, seedheads can disrupt smoothness and trueness, leading to dissatisfaction among golfers. Beyond aesthetics and playability, Poa annua also introduces agronomic challenges. It is inherently less heat and drought tolerant than bermudagrass. As temperatures rise in late spring and early summer, Poa annua often declines rapidly, often leaving voids in the putting surface. This decline is typically accelerated by disease pressure during hot, wet and humid conditions, as stressed Poa annua becomes highly susceptible to pathogens. The resulting voids reduce surface uniformity and create opportunities for further weed encroachment. Another agronomic issue is that when Poa annua is actively growing during cooler weather, ultradwarf bermudagrass greens are growing slowly, if at all. Mowing and/or rolling can help minimize the impact of Poa annua plants on ball roll, but these practices can also increase wear on the desired bermudagrass, which can lead to more opportunities for Poa annua to gain ground. As the population of Poa annua in the putting greens increases, these and other agronomic issues become more challenging to manage, so keeping Poa annua under control as much as possible is the primary goal. Fertility Program Achieving this level of surface dominance begins with a carefully balanced fertility program designed to sustain consistent growth without encouraging excessive thatch accumulation or unwanted vertical elongation. Nitrogen applications should be delivered in light, frequent increments to promote steady lateral spread and recovery, rather than flushes of growth that can lead to scalping or increased disease susceptibility. Equally important, potassium should be maintained at adequate levels to enhance plant resilience, particularly in the face of summer stressors such as heat, traffic, and periodic drought. Elevated soil phosphorus levels have been associated with increased Poa annua populations in closely mown turfgrass environments (Guertal & McElroy, 2018). Excessive phosphorus can provide a competitive advantage to Poa annua, allowing it to establish and persist more readily in putting greens and other intensively managed turf areas. For this reason, phosphorus applications should be guided by soil test results and targeted to maintain levels within agronomically appropriate ranges, thereby promoting the competitiveness of the desired bermudagrass while reducing conditions that may favor Poa annua encroachment. Rutgers University turfgrass research has noted that elevated soil pH can be associated with increased Poa annua pressure in creeping bentgrass, making pH management an important cultural tool in suppression programs (McNally et al., 2024). Maintaining soil pH in a slightly more acidic range can help strengthen bermudagrass competitiveness and reduce Poa annua populations over time. Moisture Management Moisture management is equally critical in tipping the competitive balance toward bermudagrass during the summer months. Excessively wet conditions, whether from overwatering, poor drainage or prolonged rainfall, create an environment highly conducive to Poa annua germination, survival, and eventual reestablishment. In contrast, firm, well-drained surfaces inherently favor bermudagrass by promoting deeper rooting, improved oxygen exchange, and greater heat and traffic stress tolerance. Superintendents should target a consistently moderate soil moisture profile, carefully balancing the need to prevent drought-induced stress with the equally important goal of avoiding prolonged saturation. This requires a disciplined, responsive irrigation approach, in which water is applied based on plant demand and environmental conditions rather than on fixed schedules. Allowing the surface to dry down between irrigation events not only enhances firmness and playability but also puts Poa annua at a competitive disadvantage, encouraging bermudagrass to expand laterally and occupy available space. Using portable moisture meters to guide putting green irrigation can significantly improve the precision and effectiveness of this program. By providing real-time, site-specific data, these tools allow superintendents to make informed irrigation decisions that optimize water-use efficiency and maintain optimal rootzone moisture. Improving surface and subsurface drainage is also an effective part of Poa annua control. Areas of putting greens that tend to gather and hold more water are often where a high amount of Poa annua encroachment is observed during cooler and wetter periods, so any projects that can be done to improve drainage will enhance bermudagrass health and limit the amount of moisture available for Poa annua. Cultural Practices Cultural practices during the summer should be intentionally structured to enhance the density and vigor of bermudagrass and actively disrupt the life cycle of Poa annua. Topdressing and aeration are fundamental practices for maintaining healthy ultradwarf greens, and they place Poa annua at a relative disadvantage by limiting the amount of moisture that is held in the upper portion of the putting green rootzone. Incorporating vertical mowing and grooming into the program refines surface quality and triggers new shoot growth for improved density and increased surface smoothness. The frequency, intensity and timing of all cultural practices should be carefully managed to maintain bermudagrass vigor and allow adequate recovery time. Excessive stress weakens the competitive advantage of bermudagrass, creating favorable conditions for Poa annua germination, establishment and long-term persistence. Slightly raising the mowing height on ultradwarf putting greens heading into fall can help improve Poa annua control by reducing mechanical stress on the turf. Healthier, less-stressed bermudagrass develops greater density and is better able to compete with Poa annua. The additional leaf tissue will also help maintain bermudagrass density and coverage through the winter, when wear can create voids for Poa annua to occupy going into spring. Minimizing shade on ultradwarf putting greens is another important “cultural practice” that will help minimize Poa annua issues. Bermudagrass requires high light levels to maintain density and vigor, whereas Poa annua can persist under lower light conditions. Trees or surrounding vegetation that intercept sunlight will weaken bermudagrass and create favorable conditions for Poa annua establishment. Increasing sunlight through selective tree pruning or removal can strengthen bermudagrass competitiveness and should be considered an important component of any long-term Poa annua management program. Herbicides While routine maintenance practices that support bermudagrass health form the foundation of Poa annua control, a well-structured herbicide program is essential for long-term success. Preemergence herbicides are the cornerstone of this approach. Applications should be timed to coincide with declining soil temperatures in late summer and early fall, typically when temperatures at the 2-inch depth consistently fall below 70 degrees Fahrenheit. Poa annua emergence typically occurs when 24-hour mean soil temperatures are sustained at or below 66 degrees Fahrenheit (Taylor et al., 2021). Application timing is critical: Treatments made too early may break down before peak germination, while those made too late will fail to provide effective control. Sequential applications will be required to sustain an effective chemical barrier throughout the shoulder seasons when Poa annua can most easily invade ultradwarf putting greens. Once soil temperatures are below 66 degrees Fahrenheit, applications should deliver both pre and postemergence control from varying mode-of-action groups. Advanced management programs frequently incorporate tank-mixing and rotational sequencing of multiple herbicide modes of action across the preemergence and postemergence spectrum. For example, the preemergence herbicide methiozolin (PoaCure) can be alternated with pronamide (Kerb) to balance soil residual activity, while herbicides such as amicarbazone (Xonerate) and flazasulfuron (Katana) can offer postemergence activity. Some turfgrass managers have expressed curiosity about herbicides that may be effective for controlling Poa annua but are not labeled for use on putting greens. In fact, some of these products have been studied for Poa annua control on ultradwarf greens in research settings for this reason. It is important to remember that research putting greens are not subjected to many of the stressors commonly found on golf courses, primarily traffic and shade. Additionally, the herbicide label is the law when it comes to any application. Many courses throughout the Southeast are plagued with herbicide-resistant Poa annua on putting greens, particularly populations that are not controlled with Group 2 herbicides such as foramsulfuron (Revolver). From a resistance management standpoint, rotating herbicides across distinct sites of action is not optional, it is essential. Repeated reliance on a single mode of action, particularly within ALS-inhibiting chemistries, has contributed to documented cases of resistance in Poa annua populations. A diversified, programmatic approach that integrates multiple chemistries not only improves short-term control but also preserves long-term herbicide efficacy. To expand the modes of action available for Poa annua control, some superintendents have considered or applied nonselective herbicides to dormant ultradwarf putting greens where this use is not explicitly prohibited by the product label. This type of application carries substantial risk, it is not recommended by the authors of this article, and we do not believe it should be considered a viable management option. Although bermudagrass may appear fully dormant, herbicides can still translocate to the crowns and roots, increasing the risk of turf injury, delayed spring greenup and reduced recovery. Any use of nonselective herbicides should be evaluated carefully based on product label requirements, turfgrass condition, environmental conditions, and the potential impact on spring transition. Successful implementation of an herbicide program to control Poa annua requires precise attention to turfgrass tolerance, environmental conditions and product label guidance and restrictions. Ultradwarf bermudagrass exhibits variable sensitivity to many postemergence chemistries, particularly when it is under stress or during spring transition. Applications made during periods of fluctuating temperatures, low carbohydrate reserves, or reduced growth can result in chlorosis, thinning or delayed recovery from dormancy. As such, rate selection, application interval and environmental timing must be carefully calibrated to balance effective Poa annua suppression with acceptable levels of bermudagrass safety. Managing the Presence of Poa annua Despite best efforts, many facilities will continue to contend with significant Poa annua populations in their ultradwarf greens, particularly during the fall, winter and early spring. In these situations, the focus must shift from eradication to minimizing the impact on playability. This requires a thoughtful, integrated approach that addresses both agronomic considerations and golfer expectations. During the cooler months, Poa annua will become more pronounced on putting surfaces. Mowing and rolling are essential for controlling its vertical growth and maintaining smoothness, but there must be a balance between managing the impact of Poa annua on playability and wearing down the desired bermudagrass that is growing slowly or not at all. Rolling can help mitigate the impact of seedheads and improve ball roll consistency without placing as much additional stress on the bermudagrass as mowing would, but excessive rolling during periods of slow bermudagrass growth can lead to turf thinning, particularly around putting green edges, which can lead to more Poa annua becoming established. When Poa annua populations are still scattered and individual plants are small, hand removal can be one of the most practical and precise tools available. While this process is labor intensive, physically removing isolated plants before they expand or produce seed can help protect surface uniformity without potentially weakening the bermudagrass base with herbicide applications. The key is timing. Plants should be removed by the roots while they are small enough to leave only minimal disruption to the surface, followed by careful repair so the surrounding bermudagrass can quickly knit back into the void. Bermudagrass is uniquely adapted to tolerate and respond favorably to frequent, low mowing during periods of active growth when supported by adequate fertility and moisture. Under these conditions, the turf exhibits improved density, finer texture and greater resiliency to traffic and environmental stress when mowed lower. On the other hand, Poa annua is less tolerant of sustained low mowing heights as temperatures rise and environmental pressures increase. As bermudagrass growing conditions improve, frequent low mowing further weakens Poa annua plants and reduces seedhead production. Superintendents should capitalize on this opportunity in late spring and early summer by implementing mowing practices that promote bermudagrass performance without overextending the plant. This includes maintaining sharp, well-adjusted equipment to ensure clean cuts and avoiding abrupt mowing height changes that could induce stress. Transition Back to Bermudagrass As temperatures begin to rise in spring, the transition back to bermudagrass dominance presents both challenges and opportunities. This is often the most volatile period for putting green performance, as declining Poa annua and emerging bermudagrass compete for space. Patience and restraint are essential during this time. Aggressive practices aimed at removing Poa annua too quickly can lead to unacceptable surface disruption, while insufficient management may delay bermudagrass recovery. Gradual adjustments in cultural practices such as verticutting and topdressing, can facilitate a smoother transition. Increasing nitrogen inputs to favor bermudagrass, combined with strategic aeration and topdressing, can accelerate recovery from winter and encourage the bermudagrass to fill voids left by declining Poa annua. Continued use of PGRs may be warranted to suppress any remaining Poa annua populations and maintain surface consistency. Conclusion Communicating with stakeholders is also a key component of successful Poa annua management. Golfers must understand the challenges of maintaining ultradwarf bermudagrass putting greens in regions with high Poa annua pressure. Setting realistic expectations and providing clear explanations of management strategies can go a long way in fostering support and reducing frustration during transitional periods. Ultimately, managing Poa annua in ultradwarf putting greens is a year-round endeavor that requires a proactive, integrated approach. There is no single solution, and success is rarely defined by complete eradication. Instead, the goal is to minimize impact on playability and aesthetics while promoting the long-term health and dominance of bermudagrass. Superintendents who embrace this philosophy by combining sound agronomic practices with strategic chemical inputs and effective communication will be best positioned to navigate the challenges Poa annua presents. While it may never be fully eliminated, the influence of Poa annua can be managed to a level that allows for consistently high-quality putting surfaces, even under the most demanding conditions.

Every time this podcast talks about coastal wetlands, the conversation goes straight to carbon. Marshes, mangroves, and seagrasses pull carbon dioxide out of the atmosphere and lock it in soil for centuries, and that story has earned coastal ecosystems a real seat at the climate table. Dr. Adam Langley, a global change ecologist and professor of biology at Villanova University and a research associate at the Smithsonian Environmental Research Center, thinks there's a second story hiding in that same soil that could matter just as much, or more: nitrogen. Langley and 37 co-authors just published the first global estimate of how much nitrogen the world's marshes and mangroves actually bury, and the number is staggering. Pulling from over 8,000 soil measurements across 255 tidal wetland sites worldwide, Langley's team calculated that coastal wetlands sequester roughly 3.2 teragrams of nitrogen every year, a figure Langley makes tangible by comparing it, loosely, to the mass of 700,000 African elephants or to the fertilizer applied to every cornfield in the United States. That's equal to somewhere between 13 and 15 percent of all the nitrogen buried in the world's oceans, a share nobody had managed to calculate on a global scale before this study. Nitrogen doesn't get the same climate spotlight as carbon, but its damage is intensely local: too much of it running off farmland and into estuaries fuels the algal blooms, oxygen dead zones, and red tides that can sicken and kill fish, manatees, and people. Coastal wetlands act, in Langley's words, like nature's kidneys, filtering that nitrogen out of the water and locking it away in oxygen-starved soil where it stays inert, as long as the wetland itself survives. And that's the catch. These wetlands have kept pace with sea level rise for 5,000 to 10,000 years by building soil vertically, but Langley's research suggests they can only keep up with about 8 millimeters of sea level rise a year, a threshold the global rate, now roughly double what it was 75 years ago, is edging closer to. Andrew and Langley dig into what happens on the other side of that threshold: wetland loss, boat-wake erosion along Florida's Intracoastal Waterway, and mangroves creeping poleward into places like Georgia for the first time on record, possibly helping some marshes hold their ground in the process. They also talk dollars: blue carbon's global value has been estimated at $191 billion, and Langley's team calculates blue nitrogen could be worth even more, a case he hopes gets policymakers to start managing nutrients with the same urgency as carbon. Takeaways: Coastal wetlands (marshes and mangroves) bury roughly 3.2 teragrams of nitrogen every year, drawn from a global database of over 8,000 soil measurements across 255 sites, the first estimate of its kind. That nitrogen burial equals 13 to 15 percent of the world's marine nitrogen burial. Human activity has more than doubled natural nitrogen inputs to ecosystems, arguably a bigger disruption to the nitrogen cycle than to the carbon cycle, even though nitrogen's damage shows up locally rather than globally. Blue carbon's global value has been estimated at $191 billion a year; blue nitrogen's could be even higher, an estimated $70 to $339 billion a year. Wetlands can generally keep pace with roughly 8 millimeters of sea level rise per year by building soil, but the global rate has already roughly doubled since the mid-20th century. Mangroves are expanding poleward, including a newly documented population in Georgia, which may help some marshes build soil and resist erosion better, though Adam expects overall coastal wetland area to keep shrinking as seas rise faster.

Agriculture Secretary Brooke Rollins: "Together we take the latest and perhaps the greatest at least step so far moving backward American fertilizer independence."

How do soil health practices—such as minimizing disturbance, maintaining ground cover, and promoting biological activity—interact with the 4Rs of nitrogen management to reduce runoff and nitrate leaching into water sources? How does nitrogen release (mineralize) or become tied up (immobilize) in residue depending on soil moisture, temperature, and microbial activity? Are biological soil tests (like the Haney test and Solvita CO₂ burst) precise tools for calculating exact fertilizer rates, or should they be considered general risk indexes? What role do strong soil structure and expansive root systems play in maximizing nitrogen uptake?

Dr. Eric Scherder of Corteva Agriscience returns to Farm4Profit to look back at the 2026 growing season and help farmers start building their 2027 agronomy plan. The conversation begins with cover crops and why simply getting seed on the ground isn't enough. From erosion and nitrate management to weed suppression and soil health, Eric explains why farmers need to know their objective, establish a good stand, and have a termination strategy before spring arrives.The discussion moves into weed management and the importance of starting clean, using multiple modes of action, and layering residuals—especially in early-planted soybeans. Eric challenges farmers to think beyond a one-size-fits-all herbicide program and use the entire agronomic toolbox, including cover crops, no-till, row spacing, crop rotation, residual herbicides, and emerging technologies like See & Spray. With nitrogen representing one of the largest crop investments, the guys also discuss fall versus spring application, nitrogen loss, and why stabilization matters beyond the fall application window. Eric explains the science behind N-Serve and Instinct Next Gen, why keeping nitrogen in the ammonium form can help protect it from loss, and how farmers can match nitrogen practices to the logistics and realities of their individual operations. Ultimately, the message is simple: don't treat every field the same. Use what you learned in 2026, test new ideas where they make sense, work with trusted local advisors, and build a 2027 plan around the specific challenges and opportunities on your farm.

Send us Fan MailThat “simple” gallon of milk in your fridge has a supply chain biography that stretches from fertilizer plants and global natural gas markets all the way to a refrigerated dairy case that cannot blink. We walk through the milk supply chain step by step and call out the exact moments where one mistake, one outage, or one delayed truck can turn thousands of gallons into waste.We start upstream with what most people never connect to milk: fertilizer. Nitrogen, urea, and energy costs ripple into feed prices, herd size decisions, and ultimately the price you pay at the store. Then we move through feed logistics, on-farm milking, rapid chilling in bulk tanks, and the strict testing performed by licensed milk haulers and processing plants. From there, it is all cold chain logistics: pasteurization, packaging, refrigerated warehousing, distribution centers, and the final few feet into the dairy case, often within about 48 hours.We also zoom out and compare resilience models. Much of continental Europe leans on UHT shelf-stable milk that can sit for months without refrigeration, while Australia fights the same refrigerated-milk battle the US does but across extreme distances and heat. The preparedness takeaway is practical: keep a realistic margin for error with options like UHT milk, powdered milk, and evaporated milk, and understand why the US system is efficient but thin on slack.If this breakdown helps you think more clearly about food security and preparedness, subscribe, share the episode with a friend, and leave a review so more people can find the show.https://augasonfarms.com?sca_ref=9315862.VpHzogdDNuAugason FarmsSupport the podcast.

In this episode, we cover a lot of ground as harvest officially gets underway (the earliest for Logan) in West Tennessee. We look back on our time at the Tennessee Corn Growers Association's 40th anniversary celebration and talk about just how surreal it is to see how far Talk Dirt to Me has come. Getting invited to events like this is something we don't take for granted, and we couldn't have done any of it without the continued support of our listeners. We also share some huge news: Talk Dirt to Me has officially partnered with Helena Agri-Enterprises! We're incredibly excited about what this partnership means for the show, and we talk about our upcoming trip to the Farm Progress Show, where we'll be recording live from Helena's booth. Finally, Logan has started shelling corn and shares the early results from his low-nitrogen approach this season. The corn is actually producing more bushels than the pounds of nitrogen applied, but depending on how you look at it, that could be either encouraging or raise some bigger questions. We break down the economics, efficiency, and broader implications of producing respectable yields with fewer inputs. We also talk a little whiskey in this one!  From major podcast milestones and exciting partnerships to harvest updates and nitrogen debates, this episode covers a little bit of everything.

Every season farmers face the same expensive questions: Should I spray fungicide? Does this field really need more nitrogen? Which fields deserve my attention first? How do I know the recommendation is actually right? At Tech Hub LIVE, Farm4Profit sits down with Kristine White, CEO of Spornado, and Jackson Stansell, CEO of Sentinel Ag, to explore two innovative technologies designed to answer those questions with data. Kristine explains how Spornado captures airborne fungal spores before disease symptoms ever appear, allowing growers to make preventative fungicide decisions weeks earlier than traditional scouting. The conversation also dives into fungicide resistance testing, predictive disease modeling, and the future of automated disease alerts. Jackson discusses Sentinel Ag's satellite-powered nitrogen management platform, which combines imagery, weather, soil characteristics, and proprietary calibration plots to help growers determine where—and whether—additional nitrogen is actually needed. The discussion expands into water management, nutrient efficiency, manure applications, and how AI could reshape agronomic decision-making. The conversation also explores: Disease forecasting Satellite imagery AI in agriculture Crop scouting Fungicide timing Nitrogen management Water quality Retail agronomy ROI on new technology Data-driven farming Startup innovation The future of precision agriculture If your goal is making smarter decisions before writing another input check, this episode is packed with ideas worth considering.

Nitrogen fertilizer is essential for global food security, yet its production is a hyper-centralized, fossil-fuel-intensive process that accounts for 5 to 7% of global greenhouse gas emissions. As geopolitical instability threatens traditional supply chains, the vulnerability of this industry has never been clearer. Nico Pinkowski, CEO and co-founder of Nitricity, initially set out to decentralize fertilizer production with compact devices that farmers could use right on their fields. But market realities demanded a pivot. Today, Nitricity is producing liquid organic fertilizer from recycled almond shells at a centralized facility in California. In this episode, host Lara Pierpoint talks with Nico about the "brutal reality" of scaling a new solution for a mature industry, the intricacies of financing a first-of-a-kind commercial plant, and why their mission to decarbonize a critical global commodity is more urgent than ever.

Guano and the Double-Edged Sword of Industrial Farming Guest: Stephen Moss Book Title: Ten Birds That Changed the World The story of the cormorant centers on guano, a nitrogen-rich fertilizer that once made businessmen like William Gibbs the richest commoners in England. While the Inca had used guano for centuries, the 19th-century trade was built on the tragic exploitation of Chinese indentured laborers on arid Peruvian islands. This "natural" fertilizer era eventually gave way to the Haber-Bosch process, which allowed for the mass production of synthetic nitrates. Mossargues that while this "high farming" prevented starvation, it led to a "drug addict" dependency on chemicals that has devastated wildlife. Farmland birds like the partridge and skylark have declined sharply as intensive practices destroy insects and degrade soil. Citing Rachel Carson's Silent Spring, Moss highlights that the same agricultural revolution that boosted yields also created an ecological crisis, leaving many modern fields "hopeless for wildlife."

In this episode, Bryan is joined by Matthew Taylor, a supermarket refrigeration specialist whose expertise centers on CO₂ rack systems, and Andrew Greaves, Director of User Experience at NAVAC Tools, for the third installment of their series on triple-point evacuation. The conversation expands beyond water to bring CO₂ into the picture, exploring where the two refrigerants behave similarly around the triple point and "more importantly" where the differences can create serious field problems. Whether you're pulling vacuums on residential equipment or servicing transcritical CO₂ racks at a grocery store, understanding what actually happens at these phase boundaries will change how you approach the work. The triple point of water sits at 4,579 microns, corresponding to just above 32°F (273 Kelvin). Andrew shares a fascinating piece of metrology history: for decades, the Kelvin was formally defined as one two-hundred-and-seventy-third of the triple point of water, making it the most reproducible temperature constant ever established. In practical HVAC terms, this means that any time a technician hits industry-standard evacuation targets, they pass right through the triple point of water "every single time." The danger isn't the crossing itself but what happens when moisture is present in a cold ambient: the vacuum pump can create ice, and because sublimation requires enormous energy input from the surrounding environment, that ice can persist and deliver a falsely passing vacuum reading. Andrew explains why a decay test is the real proof of a dry system, since sublimating ice will continue to raise the micron reading after the pump is isolated. The conversation also covers how micron gauges actually work: they measure thermal conductivity, not pressure, which is why refrigerant vapor entrained in compressor oil can cause wild, erratic gauge behavior that mimics both moisture and a leak simultaneously. For CO₂, the triple point arrives at roughly 70°F and 75 PSI "conditions that are easy to stumble into in the field." Matthew explains that in an operating transcritical CO₂ system, the triple point itself isn't the daily concern; the danger comes when a technician relieves pressure too quickly and liquid CO₂ flashes right through the triple point, instantly forming dry ice inside the lines and creating a hard plug. On the opposite end of the scale, CO₂ faces a critical point at just 87°F and 1,055 PSI, something that is essentially unreachable for most conventional refrigerants but is a routine operating reality in warm climates. Matthew walks through exactly what happens in a transcritical system: above the critical point, the CO₂ behaves as neither liquid nor vapor, the PT chart no longer applies, and a conventional condenser becomes a "gas cooler" that rejects heat but cannot condense the refrigerant. The refrigerant must be forced through a high-pressure valve to drop it back below the critical point, where it flashes instantly into liquid inside a flash tank. The episode also covers the "burping" behavior of CO₂ pop-off valves during high-ambient conditions, the dangers of isolating liquid CO₂, and how grocery stores have evolved from keeping spare CO₂ cylinders on hand to battery-powered fractional compressor systems that keep the flash tank subcritical through power outages. The episode wraps up with takeaways that apply across both refrigerant worlds. Big hoses and fast pumps don't eliminate moisture problems; they can actually create a false-confidence scenario where ice forms, the system still pulls deep, and the technician believes the job is done. The decay test remains the only reliable proof of dryness, and nitrogen sweeps serve multiple purposes: adding turbulence to help release refrigerant from oil, displacing refrigerant from the micron gauge sensor, and temporarily raising the system back above the triple point so ice converts to liquid before being removed as vapor. The group also briefly touches on the emerging CO₂ carbon capture industry, where the triple point is used intentionally to separate and harvest CO₂ from industrial flue gases. The world of CO₂ service is growing fast, from niche grocery racks to mini-split-sized transcritical units, and the tooling needed to work on the high-pressure side hasn't fully caught up yet. Topics Covered Triple point of water: 4,579 microns / ~32°F / 273 Kelvin, and its historic role defining the Kelvin scale Why technicians pass through the triple point of water during every standard evacuation How ice forms during deep vacuum pulls and why sublimation is slow without adequate heat input How micron gauges measure thermal conductivity, not pressure, and what causes erratic readings Distinguishing moisture, refrigerant-in-oil, and actual leaks during a decay test Triple point of CO₂: ~70°F / 75 PSI, and how dry ice forms when liquid CO₂ is vented through it Why liquid CO₂ must never be isolated and the dangerous pressure implications if it is The critical point of CO₂ at 87°F / 1,055 PSI and why transcritical operation is unavoidable in warm climates How transcritical CO₂ systems work: gas coolers, high-pressure valves, and flash tanks CO₂ system operating pressure ranges across the suction, liquid, and discharge sides Pop-off valves and the "burping" phenomenon in transcritical CO₂ systems during high-ambient conditions Grocery store power outage scenarios and battery-powered CO₂ subcooling solutions The role of crankcase heaters when pulling a vacuum on systems with oil-logged refrigerant Nitrogen sweeps: turbulence, sensor displacement, and temporary triple-point recovery Heated nitrogen as an emerging technique for improving vacuum quality CO₂ carbon capture: using the triple point industrially to harvest CO₂ from flue gases The rapid growth of smaller transcritical CO₂ systems and the current gap in high-side service tooling   Have a question that you want us to answer on the podcast?

The July Forever Strong Foundations Challenge begins July 6, 2026. This 4-week challenge is designed to help you build a stronger, more energized you through sustainable nutrition, training, and lifestyle habits. Register here: https://bit.ly/4gCmoNR For 40 years you've been told 0.8 grams of protein per kilogram is "enough" but the scientists who contributed the reports behind the new 2025–2030 Dietary Guidelines say not a single study has ever shown that number beats eating more.In this episode, Dr. Gabrielle Lyon sits down with Dr. Don Layman and Dr. Heather Leidy, the protein researchers who developed the scientific reports informing the new U.S. Dietary Guidelines, to discuss:Why the guidelines reprioritized protein to a healthy range of 1.2–1.6 g/kg and why that still isn't technically "high protein"Why you don't really have a protein requirement, but an essential amino acid requirement and what that means for your brain, mood, and antioxidant productionWho's quietly falling short: roughly 20% of women over 60 sit below the RDA, and adolescent girls are among the most consistently deficientHow to spot real protein on a label (Layman's 10-gram threshold) and why most "+protein" snacks are just fairy dustWhat a higher-protein breakfast does to afternoon cravings, backed by fMRI brain-reward dataWalk away knowing how much protein you actually need, why "enough to avoid deficiency" and "enough to thrive" are two different numbers, and how to build every meal around protein first so you're covered on the nutrients that matter most.Thank you to our sponsors:OneSkin - Get 15% off at https://bit.ly/4ekX9gt with code DRLYONExplore More from Dr. Gabrielle LyonPremium Podcast Subscription: Ad-free episodes, key takeaway summaries, exclusive Q&A, and behind-the-scenes content https://foreverstrong.supercast.comWeekly newsletter: Recipes, podcast updates, and practical weekly insights https://drgabriellelyon.com/sign-up/Apply to become a patient: Personalized care with Dr. Lyon's clinical team https://drgabriellelyon.com/new-patient-inquiry/Find Dr. Donald K.

With all of the black-and-white moralizing in our world today, we decided to bring back an old show from 2011 about the little bit of bad that's in all of us...and the little bit of really, really bad that's in some of us.   Cruelty, violence, badness... in this episode we begin with a chilling statistic: 91% of men, and 84% of women, have fantasized about killing someone. We take a look at one particular fantasy lurking behind these numbers, and wonder what this shadow world might tell us about ourselves and our neighbors. Then, we reconsider what Stanley Milgram's famous experiment really revealed about human nature (it's both better and worse than we thought). Next, we meet a man who scrambles our notions of good and evil: chemist Fritz Haber, who won a Nobel Prize in 1918...around the same time officials in the US were calling him a war criminal. And we end with the story of a man who chased one of the most prolific serial killers in US history, then got a chance to ask him the question that had haunted him for years: why?
