Impact of gypsum applications and cover crop on soybean (Glycine max) elemental composition
Abstract Soybean (Glycine max) is the most important protein crop being produced globally. Sulfur is essential for enhancing its nutritional quality, particularly by increasing S‐containing amino acids. Gypsum, which provides calcium and sulfur, and cover crops, which improve soil health and indirec...

| Summary: | Abstract Soybean (Glycine max) is the most important protein crop being produced globally. Sulfur is essential for enhancing its nutritional quality, particularly by increasing S‐containing amino acids. Gypsum, which provides calcium and sulfur, and cover crops, which improve soil health and indirectly affect nutrient dynamics, are promising management practices for enhancing soybean nutrient content. A 5‐year study across three US. locations evaluated the effects of surface‐applied gypsum and cover crops of cereal rye (Secale cereale) on continuous soybean production. The objective was to evaluate the soybean nutrient composition affected by these practices across various soil types and climatic conditions. Findings revealed consistent increases in soybean sulfur content with gypsum application, regardless of cover crop use. Responses of other elements were site‐dependent. In the case of cover crops, significant changes in element composition were observed mainly at the Ohio site. |
