Developing soil‐test‐based sulfur fertilizer recommendations for soybean
Agronomy Journal, Volume 118, Issue 4, July/August 2026.Abstract Declining sulfur (S) inputs from atmospheric deposition, combined with greater S removal by high‐yielding crops, have increased concern about S deficiency in soybean [Glycine max (L.) Merr.]. We evaluated soybean yield and leaflet‐S concentration response to six fertilizer‐S rates (0, 11, 22, 34, 45, and 67 kg S ha−1) across 50 site‐years ...
