1. Soybean Response to Tillage, Row Spacing and Nutrient Management Practices in Southern Illinois

Conservation tillage improves long-term soil health and water quality but may reduce early soybean (Glycine max L.) growth due to cooler, wetter soils and limited nutrient availability. This study evaluated integrated management strategies, including tillage, row spacing, and starter nitrogen (N) and sulfur (S) fertilization, to optimize soybean performance under Illinois conditions. Field trials were established in 2024 in southern Illinois. Two split-plot experiments were conducted:... E. Brevik, A. Sadeghpour, F. Rolle, D. Schaefer, G. Preza fontes, M. Javid
