Legumes for Nitrogen supply under water-limited conditions
November 23 @ 12:00 pm - 1:30 pm$10
Guest presenter: Dr. Mervin St. Luce (Agriculture and AgriFood Canada, Swift Current, SK).
Dr. Mervin St. Luce is a Research Scientist in Soil Fertility and Cropping Systems at the Swift Current Research and Development Center of Agriculture and Agri-Food Canada with broad knowledge of legumes in tropical and temperature production agroecosystems. He received his PhD from McGill University in 2013. His research is primarily geared towards the development of sustainable and resilient cropping systems, development of best management practices to improve soil health and resource use efficiency, particularly nitrogen and water, and the development of science-based decision support tools. Currently, his research involves the use of legumes to enhance N use efficiency, carbon sequestration, soil health and soil biodiversity in the different climatic conditions of Canada. Mervin leads several long-term studies at Swift Current, which allows him to examine the flow of legume N in soil-plant systems under a range of moisture conditions, including drought. He is an expert in understanding how soil organic nitrogen fractions contribute to crop nitrogen availability. This combined with his knowledge of legume N allows Mervin to help farmers design cropping systems that use legumes to feed both crops and the soil’s organic matter – a critical part of a sustainable organic production system. Dr. St. Luce’s expertise and ongoing research make him an excellent choice to speak about “water smart” legume systems for dryland organic production.
