Breaking Soybean Yield Barriers: Integrating Crop Production Practices & Comprehensive Fertilization Strategies – a Cropping System Approach

This project is studying the effects of different farming systems on soybean yield in major production regions of the Americas. The specific research objectives are to: 1) quantify soybean yields across various production and fertilization practices, and evaluate the interaction among these practices 2) quantify the yield gap between common farmer practice and more intensive systems, 3) measure nutrient uptake and removal across regions and cropping strategies, and 4) examine nutrient partitioning and movement between soybean plant organs.
