This project aims to determine the impacts of wet vs dry 2x2 starter, pre-plant nitrogen (N), and in-season N on soybeans. Measurements will be taken on biomass accumulation, growth and development, mineral content, N fixation, grain yield and seed quality. Another objective is to determine the effects of soybean planting date to multiple nutrient applications at different soil moisture levels. Starter fertilizer and in-season N may account for slower early-season growth or the inability to provide enough N to the seed under greater yield potentials. Finally, researchers will determine the impact of fertilizer application timings on soybean yield, biomass production, and tissue concentrations.
