The webinar will cover the design and results of an OREI project to assess the variation in how farmers manage nitrogen differently in organic processing tomato production in California, and to learn how their management affects N cycling, soil organic matter, microbial communities, plant root genes for nitrogen assimilation, and yield. We will put these results in the context of nitrogen cycling and availability in organic systems in general and some strategies to increase nitrogen cycling and yields without minimal nitrogen losses. The intended audience is researchers, extension workers and farmers.
Louise Jackson is Professor and Extension Specialist in the Department of Land, Air and Water Resources at University of California Davis. She has a long-term interest in participatory research to understand soil and root ecology. Tim Bowles is a PhD candidate in the same department, and has developed expertise in a diverse set of methods of assessing the heterogeneity amongst farms in plant-soil interactions.
