This research evaluates the response of soybeans to sulfur and nitrogen fertilization. The overall objective is to assist producers with management decisions regarding S and N yield responses as they relate to soybeans. That includes identifying yield and economic response in soybean to N and S fertilizer applications and characterizing biological nitrogen fixation in soybean and create nitrogen production budgets. Sulfur recommendations need to be established for Virginia soybean production systems if soils do not supply adequate sulfur. Soybean S sources and rates need to be investigated in sandy textured and S deficient Virginia soils as farmers’ questions are increasing yearly regarding this nutrient.
