Evaluation of Soil-Applied and Foliar Fertilization for Double Crop Soybean After Wheat.

With double crop soybean, fertilizer is typically applied prior to planting wheat and intended for both crops; when wheat nutrient removal is higher than expected this may limit nutrient supply for soybean. The objective of this study was to evaluate soil-applied and foliar fertilization for soybean grown after wheat including macro and micronutrients. All sites for this study were rain fed on no-till fields planted after wheat harvest. Macro (N, P, K), micronutrients (Fe, Mn, Zn) and S were applied at planting. Foliar micronutrients were applied at flowering (R1-R2). Tissue samples were collected prior to foliar application at R1. Pre-plant and post-harvest soil sample were collected and analyzed. The tissue and soil samples were analyzed for the nutrients applied during the study.
