This project focuses on the release timing of nitrogen and other nutrients from poultry litter and how that impacted soybean yield and nutrient composition. Poultry litter can increase soybean yields, but application timing is critical because of how those nutrients are released. Although responses varied based on soil types, environment and applications rates, trials showed clear advantages to using poultry litter. They compared three rates of poultry litter application to control plots. Littler was applied at specific timings to understand exactly when and how much of the organic nutrients in the litter were mineralized and made available to plants in the soil.
