Evaluating Struvite for Nutrient Cycling in Organic Systems

Resources You can learn more about all of the organic science cluster projects here: https://www.organic-science-canada.ca/about-us/ And specifically learn about the project discussed today here: https://www.organic-science-canada.ca/field-crops/optimizing-the-environmental-and-agronomic-co-benefits-of-recycled-phosphorus-inputs-for-organic-field-crops/ Guest bios Dr. Thiessen Martens' research focuses on nutrient flows in agroecosystems, including agronomic and environmental aspects. She is especially interested in phosphorus dynamics in soils and plants, as well as nutrient dynamics in all kinds of ecological farming systems Dr. Amarakoon's research program focuses on advancing climate-resilient, sustainable agricultural systems that enhance environmental stewardship while safeguarding surface waters and human health. Amanda is a Master’s student in Soil Science at the University of Manitoba with a background in biology and regenerative farming. Her research with the Organic Science Cluster 4 focuses on creating enriched composts using recycled phosphorus to close nutrient loops in organic agriculture. She is passionate about bridging soil and human health, growing nutrient-dense food, and building resilient systems that restore and optimize soil health.

Ian started farming in 1981 and began converting to organic farming in 1985. After 30 years of organic farming, protecting and improving the soil and managing fertility with crop rotations and off-farm inputs on 5000 acres, requires continued learning, experimentation and lots of patience. 

Creating a nutrient budget will help you evaluate the effect of nutrient management on your fields’ sustainability and help you assess efficiency and improve resource allocation. The Nutrient Budgeting Web App was developed to help with multi-year nutrient management planning, especially for producers that rely on biological nitrogen fixation and/or occasional inputs of manure or other soil fertility amendments. This multi-year approach to nutrient management planning can help to optimize production while decreasing nutrient loss to the environment by doing a better job of matching soil nutrients to crop needs.The Nutrient Budgeting App will help you calculate whether nutrients are accumulating or being depleted from your fields over time.  It makes it easy for you to add up the nutrients you are bringing onto your fields (including through N fixation by legumes) and subtract the nutrients that leave your fields to help you plan your crop rotations and soil amendments. The NBA is meant to be used alongside other nutrient management tools, such as soil testing.Whether you are an organic producer, transitioning to organic production or a conventional producer wanting to better understand how legumes in your rotation can help you reduce synthetic nitrogen use, the NAB will help you understand the efficiency and flow of nutrients in your fields.Resources linkshttps://pivotandgrow.com/resources/grain-resources/grain-production/nutrient-budgeting/SponsorOur podcast is supported by generous donations, grants and sponsorships.

Resources linksOne fantastic way to build soil health and improve the water infiltration capacity of your soil is to integrate livestock onto your land.  For grain farmers who don’t own livestock, MOA and MFGA have built a website to help facilitate partnerships between grain and livestock farmers. It’s a great way to terminate and reincorporate your green manure and build your soil biology.

He applies that passion by managing his grass-backgrounding ranch with AMP grazing, planting trees, growing food, and taking advantage of the many opportunities rural living provides. Ryan has been involved with the watershed district program since 2003. Currently he is the General Manager of the Assiniboine West Watershed. He has also been involved with organizations over the years including the Manitoba Rural Adaptation Council, the Prairie Improvement Network, and the Assiniboine River Basin Initiative.Henry WilsonResearch Scientist, Agriculture and Agri-Food Canada, BrandonHenry Wilson has been a Research Scientist with AAFC in Brandon, Manitoba since 2011. He conducts research on the hydrology, nutrient cycling, and stream ecology of agricultural systems. His current research is focused on developing knowledge to reduce eutrophication and flooding problems in agricultural watersheds, design of more sustainable and resilient production systems, and understanding potential environmental benefits and trade-offs associated with agricultural management changes. He earned his Ph.D. from the Watershed Ecosystems program at Trent University, in Ontario and was awarded a postdoctoral fellowship through the Yale Institute for Biospheric Studies, USA before becoming a Research Scientist with AAFC.
