Has soybean yield potential been reached or has it been limited by a confluence of factors such as genotypes, soil, climate and management? The answer is complex and requires comprehensive science-based tools that integrate many factors. The project goal is to improve soybean yields by using science-based mechanistic tools that measure N fixation and relevant crop/soil data during the growing season to better understand N uptake dynamics and develop robust pre-season decision support tools to provide insights into factors limiting soybean yields. The tool also forecasts soybean yields, crop growth and water/nitrogen requirements in real-time. Once the tool is fully calibrated, it can be applied to support both pre- and in-season decision making.
