Podcasts about Nitrogen

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.

The Environmental and Energy Study Institute (EESI) and the Natural Resources Defense Council (NRDC) held a briefing about tracking and reducing agricultural nitrous oxide, a major greenhouse gas. Nitrogen is a key component in fertilizer, making it critical to food security. Unfortunately, due to overapplication, only about half of nitrogen fertilizer is actually absorbed by crops. This leads to high levels of nitrous oxide emissions and threatens drinking water, ecosystems, and public health. Nitrous oxide has a global warming potential 273 times greater than carbon dioxide over 100 years and is the primary driver of stratospheric ozone depletion, increasing UV exposure and associated health risks. Nitrous oxide measurement, monitoring, reporting, and verification mechanisms are essential to reducing these emissions and supporting profitable and sustainable farm management. This briefing showcased findings from a new research roadmap that identifies opportunities for measuring and reducing agricultural nitrous oxide emissions. Panelists pinpointed areas of innovation, as well as opportunities for reducing uncertainty, improving accuracy, bringing down costs for farmers, and reducing nitrogen loss from fields. The briefing also helped policymakers identify research and development needs, and highlighted the role of federal and state legislatures in improving environmental, economic, and public health across the country.

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.

Have you heard of Nostoc? It's scientific name, Nostoc commune, sounds like a chat between Trump and Putin but it's actually a living organism that troubles more than a few Kiwis on their quarter acre paradise. Brown-green “gorilla snot” is another name, star jelly, witch's butter, and mare's eggs... But most folk call it brown, slimy scum. It's a colony of cyanobacteria (blue-green algae) that form dense gelatinous mats of slimy and leathery bits and pieces on driveways, gravel, and bare soil. It is usually terrestrial but can also be aquatic (such as in wet paddy fields). The trouble with this stuff is its persistence and difficulty to control. It reproduces by binary fission, meaning each cell simply splits in two when conditions are suitable. Gardeners often complain that it thrives on Roundup weedkiller, and most other weedkillers for that matter (I doubt that, by the way!!). Chlorine and salt don't work, and bleach simply runs off the rubbery squishy invader. Copper sulphate and sodium hypochloride are also ineffective. On the various online “help me” websites (hilarious to read, by the way) people state that some Benzalkonium chloride (a quaternary ammonium compound often used as an algaecide) may be the answer. Why is it so difficult? Nostoc occurs anywhere from the tropics to the dry valleys in Antarctica – an impressive range of climatological conditions. In summer it dries out to a crispy, brown material, while in winter it's lush, soft, and spongy, and blueish green or olive green. It's particularly good at coping with water stress. A colleague once did some experiments showing that it could lose more than 70% of its weight in water before cell metabolism was affected – hence its success on driveway shingles. It grows on alkaline soils in the tropics and doesn't care about brackish water either. It's resistant to heat as well as continuous freezing/thawing cycles and it produces no oxygen when it's dormant. Despite the fact it hasn't got Chloroplasts, it can fix Nitrogen from the atmosphere. Nostoc is eaten in Asia, but it's not recommended (there have been some suggestions of toxicity). Having said that, some varieties (such as Nostoc commune var. sphaeroides) may be beneficial by means of an anti-inflammatory mechanism. So… how do we control it on our driveways? Good question! Let us know your success stories… LISTEN ABOVESee omnystudio.com/listener for privacy information.

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."

The recent geopolitical challenges have shined a spotlight on how fragile our global fertilizer infrastructure can be.

In this week's episode of the Kite Podcast, Will Evans and Ben Eagle are joined by Erik Elgersma, Founder and Director of Strategic Analysis Services BV, and podcast producer Becki Reay, as they head to the Netherlands to examine the Dutch government's latest nitrogen reduction plans and what they could mean for the future of dairy farming. Proposed measures include tighter restrictions on farms located near Natura 2000 environmental protection sites. Erik explains the background to the plans, the challenges facing Dutch agriculture, and the Dutch government's ambitious targets to reduce nitrogen emissions by 2035. Together, the team explores what these changes could mean for Dutch milk production, whether they could lead to a smaller dairy sector, and if they might set a precedent for other countries across Europe. They also discuss why UK farmers should be paying close attention to these developments. Chris Walkland returns with his usual Milk Market Report and shares his insights into how the recent heatwave is affecting milk production levels and wider dairy markets.

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?

In 1972, two scientists reported the discovery of a very strong magnet. Their paper said: We found a new magnetic material which has the highest saturation magnetization at room temperature...among those of all the magnetic materials. Not only is this material one of the most magnetic objects known, it is made from two very ordinary elements: Iron and Nitrogen. For forty years, people went back and forth on whether this magnetism was real. In this video, we explore the decades-long mystery of the Iron Nitride magnet.

Sean and Andrew are back with Purdue's Dr. Ignacio Ciampitti to learn how nitrogen management and digital innovations research can be translated into practical solutions for growers.    The crew discusses: ✅ The reality of nitrogen management ✅ What most growers are doing wrong when it comes to nitrogen ✅ How growers can make more informed decisions ✅ Turning formal research into practical management decisions ✅ How digital innovations are changing the way we farm   Meet the Guests:

As growers look to manage tighter margins, there’s a stronger focus on nitrogen use efficiency and making sure more of every pound applied is available when the crop needs it. NAFB News Service See omnystudio.com/listener for privacy information.

Oklahoma summer crops may look smaller than usual, but that does not automatically mean yield potential is gone. Dave Deken talks with Brian Arnall Ph.D. and Josh Lofton Ph.D. about how timely June rains, cooler temperatures, and still-uncertain July weather are shaping corn, soybeans, grain sorghum, hay, and double crop decisions across the Southern Plains. The conversation covers why smaller soybeans can sometimes offer better yield stability in dryland Oklahoma, what corn needs during pollination, how growers are thinking about double crop acres after an early wheat harvest, and where fertilizer dollars may be best spent with current nitrogen, phosphorus, potassium, and lime prices. Brian also shares lessons from Brazilian row crop systems, and the team previews a hands-on OSU Extension summer crop field day in Chickasha. Key takeaways June rain changed the summer crop outlook. After a dry start, many Oklahoma fields caught enough rain to germinate and carry crops forward. Smaller crops are not automatically bad. In dryland Oklahoma, shorter soybeans and sorghum may use less water and hold up better if July turns hot and dry. Corn is in a critical window. Cooler temperatures in the 70s and 80s could help early planted corn during pollination. Soybeans are already moving. Some April-planted soybeans are flowering, but wide-row fields that have not canopied may face more weed pressure. Double crop decisions remain complicated. Moisture is favorable in places, but prices, risk, and plans for next wheat crop are slowing some decisions. Some growers may invest in existing acres first. Instead of adding more double crop acres, producers may spend fertility dollars on full-season corn, sorghum, or soybeans. Hay and forage acres may increase. Hay grazer could see more interest as producers rebuild hay supplies for winter. Potassium and lime may deserve attention. Brian points to K and lime as places to invest where soil tests show a need, while staying cautious on expensive N and P. Fertilizer markets are global. Nitrogen, phosphorus, and potash prices are being shaped by international demand, freight, geopolitics, and timing. Brazil offers useful contrasts. Brian's trip highlighted major differences in soils, rainfall, row crop systems, planter setup, fertility, and crop disease pressure. Detailed timestamped rundown 00:00–01:43 — Episode setup and introductions Dave introduces episode 513 and frames the discussion around moisture, cooler weather, wheat harvest, summer planting, and what has changed across the Southern Great Plains.01:48–04:55 — Weather whiplash and wet wheat harvest areas The group jokes about June feeling like winter and discusses wet conditions in northeastern Oklahoma, including areas where wheat harvest had been delayed by repeated rainfall.04:55–07:18 — “Weird things called rain” Josh explains that after a very dry early spring, rain finally arrived. Instead of one big soaking event in many areas, crops benefited from more spread-out rainfall.07:18–09:37 — Double crop decisions and crop progress The group discusses wheat coming off, double crop choices, cooler temperatures, corn approaching pollination, and early planted soybeans beginning to flower.09:37–13:10 — Josh's research projects Josh outlines current work, including crabgrass and small grain rotations, nitrogen management, forage production, soybean and sorghum herbicide work, and pigweed control research.13:10–14:16 — How research programs evolve Brian and Josh talk about how Extension research shifts through phases based on grower needs, student interests, funding, and emerging problems.14:16–17:02 — Summer crop acreage trends Josh says corn interest increased after strong performance last year, soybeans remained steadier than expected, and marketing conditions have made decisions feel like choosing the least bad option.17:02–18:40 — Early wheat harvest and double crop caution Brian notes how early wheat harvest was in some areas. Josh says some growers are considering whether to double crop or prepare ground for wheat again.18:40–19:44 — Fertility and hay grazer decisions Josh says some growers may spend money on full-season acres instead of double crop acres, while also considering lime, phosphorus, potassium, and hay grazer needs.19:45–20:55 — Bermuda grass and hay outlook Brian notes Bermuda grass started slowly because of the dry, cool start, but second cuttings may look stronger. Josh adds that eastern Oklahoma avoided some flooding problems seen in previous years.21:08–22:23 — Dry planting, then June moisture The group compares expectations at planting with current field conditions and notes that Oklahoma growers would rather have moisture in June than early growth with no rain later.22:23–24:02 — Why small crops may be okay Josh introduces the idea that smaller soybean and sorghum plants may offer yield stability in Oklahoma by lowering water demand.24:02–26:21 — Soybean height, canopy, and weed pressure Josh explains that large soybean plants can support more yield in unlimited conditions, but they also require more water. Shorter plants may protect yield if July dries out, though wide rows that have not canopied may face weed pressure.26:21–27:09 — Grain sorghum size and drought fit Josh says sorghum is smaller than recent years but is beginning to boot in some places, which may be a good fit if heat and dryness return.27:09–30:27 — Corn's narrower flexibility Brian and Josh compare soybeans, cotton, sorghum, wheat, and corn. Corn can handle cool conditions well, but it has less flexibility than indeterminate crops once it commits to yield structure.30:27–33:24 — Data behind small-crop thinking Josh explains past soybean work with plant growth regulators and crop topping. In stressful years, smaller crops protected yield; in non-limiting years, taller crops could have an advantage.33:24–36:02 — Why topping soybeans is not a recommendation Josh clarifies that physically topping soybeans is not a recommended practice. Instead, planting date, irrigation, and system fit are better levers for managing crop size.36:02–37:38 — Double crop soybeans west vs. east Josh explains that farther west, double crop soybeans can sometimes compare more favorably with full-season soybeans because shorter vegetative growth may better match moisture limitations.37:38–39:24 — Weather pattern uncertainty Dave asks about changing weather patterns. Josh says producers should not overhaul whole-farm practices based on one season, but repeated issues with overly tall crops may justify revisiting planting windows.39:24–42:03 — Wheat harvest and fertility strategy Brian says many wheat fields under-yielded and fertilizer spending was down. He recommends looking at current prices and soil needs instead of assuming last year dictates this year.42:04–47:17 — Fertilizer markets and geopolitics Brian discusses urea, phosphorus, potash, lime, international fertilizer movement, and why nitrogen prices do not respond instantly to shipping news.47:17–48:40 — Brazil's role in fertilizer demand The group discusses how Brazil's crop demand, transportation constraints, tariffs, and global trade shape fertilizer movement and pricing.48:40–52:17 — Brian's Brazil agronomy trip Brian describes visiting Pará, Brazil, where row crop systems are relatively new, soils are deep and highly weathered, rainfall is extreme, and soybean systems depend heavily on fungicide.52:17–54:06 — What Oklahoma can learn from Brazil Brian reflects on how newer production regions may be more open to ideas, while also facing unproven products and unique fertility, soil, and equipment challenges.54:06–57:27 — Chickasha Summer Crop Demo Day Brian previews the July 27 producer event at the Chickasha research station, including hands-on stops for crop staging, scouting, soil pits, irrigation, spray nozzles, nitrate testing, alfalfa, and summer crop management. The related OSU event listing describes hands-on demonstrations from soil pits to crop scouting to improve summer crop productivity.57:27–59:32 — Wrap-up The group closes with the show website, resources, and a reminder for listeners to send questions through Red Dirt Agronomy.

It's June, your tomatoes are climbing, your corn is waist-high, and the internet is full of fertilizing advice—most of it missing the most important variable: timing. In this episode, we dig into what your vegetables need right now at mid-season, why nitrogen timing is the thing most gardeners get wrong, how fruiting crops and leafy crops have completely different needs, and when fertilizing can actually hurt instead of help. We'll cover how to read your plants for deficiency signs, how to side-dress correctly, and why the most common mid-season mistake isn't under-fertilizing—it's fertilizing at the wrong time with the wrong form. Grounded in university extension research and my own experience farming through Missouri summers, this one will give you a clear, crop-by-crop picture of what to do right now. Let's dig in. Crop-by-Crop Quick Reference: Mid-Season Nitrogen Timing LEAFY CROPS (lettuce, kale, chard, spinach, collards, arugula, basil) When to side-dress: 3–4 weeks after transplanting or when 2–3 inches tall; repeat every 4–6 weeks for heavy-harvesting crops Goal: steady nitrogen supply throughout season Note: don't exceed recommended rates—excess nitrogen increases pest/disease vulnerability COLE CROPS (broccoli, cabbage, cauliflower) When to side-dress: approximately 30 days after transplanting, during active vegetative growth Hold off once head formation begins TOMATOES When to side-dress: when first fruits are approximately one-third grown (golf ball size) DO NOT apply nitrogen at transplant or during early fruit set—drives vegetative growth at expense of fruit Second application: 2 weeks after first ripe fruit; third: 4 weeks later Rate: 0.5 lb actual nitrogen per 100 feet of row per application PEPPERS When to side-dress: early vegetative growth before fruit set Pull back after fruit is setting SWEET CORN When to side-dress: when plants are approximately one-third grown (knee-high) Apply alongside rows, not into the whorl of leaves May benefit from a second application before tasseling CUCUMBERS / SQUASH / MELONS When to side-dress: after vines are well-established and fruit is setting regularly Not during early flowering window For squash with blossom drop only: do not add nitrogen—address pollination instead BEANS / PEAS (inoculated) Mid-season nitrogen side-dressing generally not needed if seeds were inoculated Extra nitrogen causes excessive leaf growth and reduced pod set If not inoculated: apply light nitrogen early in vegetative growth only Side-Dressing How-To Move mulch aside before applying; replace afterward Keep granular fertilizer 4–6 inches from plant stems to prevent burn Work granular into top 1–2 inches of soil Water in after application—nitrogen moves into the root zone with moisture Organic options: blood meal or alfalfa pellets (work in lightly; slower to show results); fish emulsion (liquid, faster uptake, more frequent application needed) Signs of Nutrient Deficiency Nitrogen: yellowing starting on oldest, lowest leaves; stunted or stalled growth Phosphorus: stunted growth; reddish-purple tint in leaf tissue (often triggered by cold soil, not low soil P) Potassium: browning at leaf edges, starting with older leaves Note: many of these symptoms overlap with stress from crowding, insufficient sun, compaction, waterlogged roots, or nematode damage—rule those out first Common Myths Addressed Myth: More fertilizer = more production. The research is clear: overapplied nitrogen causes excess vegetative growth at the expense of fruit, increases pest and disease vulnerability, and leaches into groundwater without benefiting plants. Myth: If plants look off, they need fertilizer. Nutrient deficiency symptoms look almost identical to symptoms of watering problems, compaction, pH issues, root damage, and pest pressure. Identify the actual cause before applying anything. Myth: Tomatoes need nitrogen all season long. Timing matters. Nitrogen during the early fruit-set window drives vegetative growth and reduces yields. Wait until fruit is sizing up before side-dressing. Myth: Beans and peas are heavy feeders like corn. Inoculated legumes fix their own nitrogen from the air. Additional nitrogen pushes leaf growth at the expense of pods.

Can a pair of autonomous robots feed a corn crop exactly what it needs, when it needs it, while using less nitrogen and increasing yield? That's the question Brucelea Poultry field crops manager Mark McLean hopes to answer in a field-scale trial near Ripley, Ont., where two autonomous robots from Upside Robotics are managing nitrogen...

USDA REPORT DAYThe June 11, 2026, Closing Market Report covers updates on agricultural commodity markets, upcoming extension events, agronomic research, and global weather patterns. Jim McCormick of AgMarket.net noted that the USDA's June WASDE report introduced largely bearish global supply revisions for corn, wheat, and soybeans, contributing to lower market closing prices across the board. In agronomic news, Travis Meteer previewed the June 17 Dudley Smith Farm field day, an event connecting beef and row crop producers with University of Illinois researchers to discuss nutrients, water quality, and fertility management. Additionally, agricultural economist Gary Schnitkey highlighted findings from 11 years of Precision Conservation Management data, showing that utilizing no-till or one-pass light tillage systems—alongside maintaining nitrogen rates near the Maximum Return to Nitrogen limit—consistently provides the highest profitability for farmers. Finally, Mike Tannura of T-storm Weather reported that recent intense storms have sufficiently moistened the U.S. Corn and spring wheat belts, while looking abroad, a severe heat wave is expected to negatively impact crops in France, Italy, and Spain next week.- Ag Markets with Jim McCormick, AgMarket.net- June 17 Dudley Smith Farm Field Day Preview- farmdoc Webinar Explores Tillage & Nitrogen Practices- Ag Weather with Mike Tannura, Tstorm.net ★ Support this podcast ★

https://agxplore.com/assessment/ How do top growers consistently push yield boundaries while still focusing on return on investment? In this special Farm4Profit episode recorded from the AgX booth at Commodity Classic, Tanner and Corey sit down with AgX Sales Agronomist Billy Carter and three progressive farmers who are proving what's possible in modern agriculture. Minnesota farmer Ron Pagel shares how he surpassed the 300-bushel corn mark by combining advanced fertility programs, drone applications, fungicide timing, and a commitment to trying new ideas. Wisconsin farmer Dave Justman discusses balancing farming, retail agronomy, and the pursuit of higher-yielding soybeans while helping customers implement proven agronomic practices. Kentucky farmer and Kentucky Soybean Association President Jonathan Reynolds explains how conservation practices, cover crops, no-till management, and long-term soil health improvements have created a foundation for both yield and profitability. Throughout the conversation, Billy Carter breaks down the agronomic principles behind AgX's high-yield programs, including seed treatments, fertility management, fungicide strategies, plant growth regulation, hybrid selection, and the importance of focusing on details many growers overlook. Topics include: Breaking the 300-bushel corn barrier Building profitable high-yield systems Contest plots versus whole-farm ROI Cover crops and soil health as yield drivers Fragipan soils and improving water infiltration Nitrogen efficiency and fertility management Hybrid and variety selection strategies Drone applications and late-season management High-yield soybean challenges and opportunities The role of mindset, observation, and continuous learning Whether you're chasing yield contest results or simply looking to improve efficiency and profitability across your operation, this episode delivers practical lessons from growers who are constantly pushing the limits of what's possible in the field.

Recorded live at the Florida Ruminant Nutrition Conference, this episode of the Real Science Exchange explores how improving nitrogen efficiency can enhance both dairy performance and environmental sustainability. Featuring Dr. Kelly Nichols (UC Davis), Dr. Jonas de Souza (Perdue Animal Nutrition), and Dr. Ben Wenner (Feed Works), the conversation brings together leading perspectives on how nitrogen utilization continues to shape modern dairy nutrition programs.

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?

In this action-packed live stream episode of HVAC School, host Bryan is joined by Eric Kaiser, Ty Branaman, and Roman Baugh for a continuation of a deep-dive conversation on vacuum practices — picking up where a previous episode left off with Andrew Greaves and Jim Bergmann. The team sets out to both reinforce the foundational best practices every HVAC technician should follow and to explore some genuinely uncharted scientific territory around how vacuum gauges actually work, how refrigerant contaminates micron gauge readings, and what really happens to moisture inside a system when temperatures drop below freezing. A central revelation of the episode is Eric's explanation that modern electronic vacuum (micron) gauges do not actually measure pressure directly — they measure heat transfer and translate it into a pressure reading. Because these gauges are calibrated to nitrogen or air, the presence of refrigerant vapor in a system (which has roughly three times the heat conductivity of nitrogen) can cause the gauge to display a falsely high reading. This means a technician could believe the system still has poor vacuum when it may actually be further along than indicated — or, more concerning, that a system appears to have passed vacuum when contamination is still present. The team acknowledges that controlled experiments are needed to quantify exactly how much refrigerant affects the reading, and they commit to designing those tests. The conversation then pivots into the physics of water at the triple point — the precise pressure (4,580 microns) and temperature (32°F) at which water can exist simultaneously as solid, liquid, and vapor. Eric walks the audience through a phase diagram built from International Association for the Properties of Water and Steam data, explaining that once pressure drops below the triple point, liquid water no longer exists. Any moisture in the system either sublimes directly from solid ice to vapor or remains frozen. This has major practical implications: a system with ice inside can still pull down to a very deep vacuum, but will not pass a decay test until that ice is fully sublimated — which requires both sufficient vacuum depth and available heat energy. The colder the ambient environment, the deeper the vacuum must go to create the temperature differential needed to drive sublimation. The episode wraps with an illuminating discussion on refrigerant oils — specifically the differences between POE (polyolester) and PVE (polyvinyl ether) oils and how each interacts with moisture in fundamentally different ways. POE chemically bonds with water through hydrolysis, breaking down into acid and alcohol and permanently degrading the oil. PVE, on the other hand, physically traps moisture through surface tension and can hold up to twice as much water as POE, but remains chemically stable. This distinction affects vacuum strategy, dryer sizing, and long-term system reliability — particularly in VRF and cold-climate heat pump systems where compressor oil management is far more complex. Topics Covered Core vacuum best practices refresher: large hoses, removing valve cores, skipping the manifold, using clean pump oil, micron gauge placement, and decay testing Why micron gauges measure heat transfer — not pressure — and how refrigerant vapor causes false-high readings on the gauge The impact of refrigerant retained in compressor oil on vacuum accuracy and the potential role of nitrogen sweeps in displacing refrigerant molecules Triple point science: what happens to moisture when pressure drops below 4,580 microns and why liquid water no longer exists below that threshold How ice inside a system can allow a deep vacuum pull-down while still failing a decay test, and what that means for cold-climate HVAC work The role of heat during evacuation: why adding heat accelerates moisture removal and how deep vacuum increases temperature differential to drive sublimation Cold-climate challenges: vacuum pump limitations, micron gauge accuracy at low temperatures, and the physics of dry air in freezing environments Triple evacuation and nitrogen purging: whether nitrogen disrupts oil pockets, displaces refrigerant, or both — and why the team wants to test it Nitrogen tank quality concerns: the possibility that low-grade nitrogen could introduce moisture and whether an inline dryer would help Using system flush chemicals: why Ty cautions against flushing agents and the risks of adding additional chemicals that break down oil POE vs. PVE oil chemistry: how POE undergoes hydrolysis when exposed to moisture (creating acid) versus how PVE physically traps water without chemical breakdown Dryer strategy for large commercial systems, VRF, and VRV: filter dryer sizing, core pulls, oil sampling, and why an "oil dialysis machine" would be a game-changer Plans for future controlled experiments: testing refrigerant effects on micron gauges, ice behavior at various temperatures, and vacuum performance in cold climates Industry influence over time: how community-driven knowledge sharing has already shifted vacuum and refrigerant practices over the past decade Whether you're a residential technician looking to sharpen the fundamentals or a commercial refrigeration specialist wrestling with VRF oil contamination, this episode delivers both practical takeaways and a front-row seat to the scientific inquiry that drives best practices forward.
