Core Ideas Soil K at 0‐ to 15‐ and 0‐ to 30‐cm depths were excellent predictors of full‐season soybean relative yield. Tissue‐K concentration can be used for calibrating fertilizer‐K rate and in‐season K management. Soil sampling to 30‐cm depth would reduce fertilizer amount and cost for soybean on ...

Abstract Double cropping winter wheat ( Triticum aestivum L.) and soybean [ Glycine max (L.) Merr.] increases total food production without additional land. However, yield and/or quality of both crops often suffer if wheat harvest is delayed beyond maturity. We evaluated the impact of high‐moisture ...

Core Ideas Soil K at 0‐ to 15 and 0‐ to 30‐cm depths were excellent in predicting double‐crop soybean relative yield. Double‐crop soybean required more fertilizer K to maximize yield than current recommendations. Fertilizer‐K rate can be reduced if recommendations are made based on 0‐ to 30‐cm than ...

Core Ideas Soil K extracted by each processing method were similar and strongly correlated with relative yield. Soil K from FM, AD, and OD soils were equally good in predicting yield response to fertilizer‐K. Soil drying should not be an issue of concern in extracting soil K from soils in the US Mid...

Abstract Double cropping soybean [ Glycine max (L.) Merr.] after winter wheat ( Triticum aestivum L.) increases total food production without additional land. However, double‐crop soybean usually yields less than full‐season soybean, mainly due to late planting. We evaluated double‐crop soybean grow...

Abstract Soybean [ Glycine max (L.) Merr.] after winter wheat ( Triticum aestivum L.) is the most common double‐cropping system in the United States, driven by the desire for increased cash flow and profits and bolstering global food security. Despite its popularity, double‐cropping often results in...

Abstract Selecting an appropriate relative maturity group (MG) soybean [ Glycine max (L.) Merr.] for a geographic location within a state is a crucial factor in ensuring profitable soybean production. Choosing an inappropriate MG can significantly reduce yield. We determined the probability of a rel...
