Dr. Clain Jones is Montana State University Extension's soil fertility specialist. In this role he covers anything that has to do with fertilizer or nutrient cycling in both agriculture as well as home/garden systems. He started at MSU as a tenure track faculty member in 2006, and has ended up doing quite a bit of work with pulse crops over the years. He joins me today to talk about fertility in pulses, the importance of inoculation, nitrogen credits, soil pH, and the overall importance of pulse crops to soil health.“Adding five pounds of sulfur per acre to lentils, what we found at least here in Bozeman, was that nitrogen fixation increased at a much faster rate than yield did. What that told us was that by applying sulfur, maybe we're not going to see a huge yield response, but we're going to contribute a lot more nitrogen both to that crop and to the next crop.” - Dr. Clain JonesDr. Jones stresses the importance of plant nutrition and pH when it comes to optimizing a pulse crop's ability to fix nitrogen. Limestone deposits in the soil can make pH values highly variable even within a field. This can make accurate soil testing a challenge. An acidic pH has a significant impact on rhizobia viability as they don't tolerate low pH values very well. Along with pH, many micronutrients such as sulfur, potassium and phosphorus also need to be considered when assessing overall soil health and nitrogen fixation efficiency.“We have low phosphorus because our high levels of calcium tie up that phosphorus making it less available to crops. Knowing that phosphorus is essential for nitrogen fixation, my gut feel is that phosphorus is probably the nutrient most limiting nitrogen fixation and probably pulse crop growth in our two state region.” - Dr. Clain JonesThis Week on Growing Pulse Crops:Meet Dr. Clain Jones, the Montana State University Extension's soil fertility specialistDiscover the impact of pH and micronutrients on a pulse crop's ability to fix nitrogenExplore the recommended testing and values of soil nutrition to allow for optimal nitrogen fixationGrowing Pulse Crops is produced by Dr. Audrey Kalil and hosted by Tim Hammerich of the Future of Agriculture Podcast.

Dr. Chris Graham is an associate professor at South Dakota State University. He's also the manager of the West River Research Farm near Sturgis, South Dakota. At that facility they focus a lot on regenerative agriculture, including doing a lot of work with peas and other pulses to extend crop rotations in that semi-arid region in the western part of the state. Graham shares about pulse production in South Dakota, focusing mostly on field peas. He also shares some of the complexities of nitrogen fixation, including what it might look like to have farm-specific microbial inoculant mixes in the future. “When you look at the growth of wheat, generally the yield is set first and then the protein is made later in its life cycle. And so we often see peas, obviously they're harvested and they start to decay, and that slow decay releases nitrogen later in the wheat growing season. And so we often see a protein bump with wheat following peas.” - Dr. Chris GrahamWhile there isn't a lot of acreage in pulses in South Dakota yet, Graham calls field peas the “nickel slots” of the pulses. In other words, a great place to start incorporating them into a rotation with a low barrier to entry. He highlights that your soil nitrogen content will likely not increase but your input needs may decrease when pulses are used.“It's still nitrogen that you didn't have to apply and it's also nitrogen that the plant did not necessarily take up from the soil. And so it's conserving some of that nitrogen that's being made available just on that baseline level. ” - Dr. Chris GrahamThis Week on Growing Pulse Crops:Meet Dr. Chris Graham, an associate professor at South Dakota State University and the manager of the West River Research Farm near Sturgis, South DakotaExplore the potential use of pulse crops in rotations in South DakotaDiscover the niche pulses can fill in rotation as a broadleaf crop capable of nitrogen fixationVisit Dr. Graham's webpage here.Growing Pulse Crops is produced by Dr. Audrey Kalil and hosted by Tim Hammerich of the Future of Agriculture Podcast.

Microbial consortia are groups of diverse microorganisms that have the ability to act together in a community. Such consortia are common in nature and are known to play important roles in many ecosystems but are not always well understood. Soil management and nutrient mobilization are one area where complex communities of microbes are known to be important, whether it be a naturally occurring consortium, or a man-made consortium.  In this episode of Absolute Gene-ius Jordan and Cassie talk with Dr. Ray Ketchum form Agrinos about the microbial consortia he and his team cultivate and produce to improve plan health and increase crop yields. We learn about the challenges of fermenting mixtures of more than 20 diverse microorganisms to reproducibly make products that improve plant health and mobilize nutrients in a completely organic way. As you might expect, digital PCR plays in important role in Ray's R&D and quality control process.  Here, they use dPCR to titer each of the species within their consortia for quality and regulatory purposes, a task that cannot be done by cell culture methods given the range of bacteria involved. Cassie's career corner gets Ray sharing his full career development story from undergraduate, through grad school and postdoc positions, and into his professional career. Ray is generous in sharing his early misconceptions about miscalculations while providing advice to help other avoid similar missteps.  Visit the Absolute Gene-ius page to learn more about the guest, the hosts, and the Applied Biosystems QuantStudio Absolute Q Digital PCR System.

Dr. Barney Geddes is an assistant professor at North Dakota State University in the Department of Microbiological Sciences. His work focuses on microbes with the goal of boosting crop yields for farmers. More specifically he studies rhizobia which form symbiotic relationships with legume crops like pulses. In this episode, Geddes explains how nodulation works and what that means for farm decisions like inoculants. He grew up on a farm in Manitoba, and after studying microbiology as an undergrad, he decided to apply this knowledge to his lifelong passion for sustainable agriculture. His perspective is deep into the science but also rooted in the reality of growing up on a commercial farm. “Nodulation or the ultimate formation of a root nodule on the root of these pulses is really the result of quite an elegant communication and signal exchange between the plant and the microbe…It's really a communication between the two that ultimately leads the plant to understand it has the right microbe there to allow it to kind of gain entry and then it builds this house for it called the root nodule.” - Dr. Barney GeddesAccording to Geddes, inoculation is “kind of a bet hedging process” in that producers are just making sure all the building blocks are made available for nodulation to occur. The plant will continue to send out signals to create nodules and will turn off those signals once they have met their needs. In this way, if there is excessive nitrogen in the soil, the plant will not be prompted to form the symbiotic relationship and nodulate. Plant stress and soil pH will also impact the symbiotic relationship and the success of nodulation.“We're trying to build a translatable knowledge base that can lead to improvements in the industry. So that's been a big focus for us, is competition. These are living organisms that have to come into our environment and thrive there somehow…But thinking about that competition and, and what allows a microbe to thrive in a new environment is something we're starting to do a lot.” - Dr. Barney GeddesThis Week on Growing Pulse Crops:Meet Dr. Barney Geddes an assistant professor at North Dakota State University in the Department of Microbiological SciencesExplore the intricacies of nodulation and the components that make it successful in the fieldDiscover the best use scenarios for inoculants to encourage nodulationGrowing Pulse Crops Podcast is hosted by Tim Hammerich of the Future of Agriculture Podcast.

Free Living Nitrogen Fixation (FLNF) is where organisms in the soil fix nitrogen from the atmosphere and make it plant available in the soil. Unlike rhizobia found in legumes these organisms aren't fixed to a plant and live freely in the soil with some producing more nitrogen than their legume equivalents. But unlike the rhizobia in legumes FLNF is mostly unknown but potentially has a large role to play in the farming system going forward as agriculture looks to reduce its carbon emissions and find more sustainable and regenerative methods for maintaining nitrogen in the farming system. Listen to todays Podcast to find out more about Free Living Nitrogen Fixation, how it can benefit you and how you can encourage it in your paddocks.

Episode 4 of 22: Nitrogen fixationIn this episode of ‘We've bean around the block', host Antony Jarvie discusses nitrogen fixation with UKZN's Professor Mark Laing. The discussion is centred around nitrogen fixation in soybeans, but it broadens into a discussion that covers legumes and non-legume crops. The fragile Bradyrhizobium japonicum used in soybean production is not indigenous to South African soils, so it needs to be inoculated at planting. The importance of out-competing other microbes and wild strains of rhizobia is discussed, as is the need to inundate the rhizosphere with the desired highly efficient N-fixing strains. The most widely used rhizobia strain (WB74) has been deployed for more than 20 years, and current soybean cultivar selection has been optimised on this strain. With climate change, soil environment conditions are changing rapidly, and there was much debate around the requirement for strain improvement to meet these changes. There are allied microbes that we should be developing alongside the rhizobia to buffer their exposure to harsh conditions. Professor Laing went on to introduce the topic of nitrogen fixation by free-living microbes. The examples given included N-fixation in sugar cane, cereals such as wheat and maize and in forestry. His own ground-breaking research is poised to commercialize a N-fixing Bacillus species, which could contribute towards reducing agriculture's reliance on fertilizer nitrogen. For those interested in this topic, the links provided below offer some peer-reviewed scientific articles on the topic. https://www.tsnf.org.uk/wp-content/uploads/2019/08/Cocking-and-Dent-2017.pdfhttps://pubs.acs.org/doi/pdf/10.1021/acssynbio.1c00049 

Ray Dixon is a microbiologist at the John Innes Centre in the UK. He's currently the Co-Director JIC-CAS Centre of Excellence in Plant and Microbial Science. Dixon has been working to understand the unique relationships between agricultural crops and nitrogen-fixing bacteria. These special bacteria live in the soil, converting nitrogen existing in the atmosphere into a form that can be taken up by plants. Legume crops, like alfalfa, clover, beans, lentils, and even leguminous trees like locust, have the ability to create a symbiotic relationship with these bacteria if they are present in the soil, a benefit that both small and large scale farmers across the world have been utilizing for millennia. If the symbiosis between legumes and nitrogen fixing bacteria could be engineered to work with other crops like cereals, it could provide farmers, consumers, and the environment with huge positive benefits. However, the exact functions that allow this process to happen are incredibly complex and scientists don't know everything about them. Researchers like Ray Dixon and his team at the John Innes Center are working hard to characterize the bacteria and their processes in hopes that specialized plants and associated nitrogen fixing bacteria could be co-developed, giving farmers high-yielding crops that preserve and restore soil health without requiring costly and potentially polluting synthetic fertilizers.

Manish Raizada, Professor in the Department of Plant Agriculture, University of Guelph and Marcus Meadows-Smith, CEO of BioConsortia talk with IFA's Deputy Director-General, Patrick Heffer, about the benefits and potential of Nitrogen-fixing microbials as a tool available to farmers to improve plant nutrition.
