Near‐surface soil property changes affected by management practices in a long‐term, wheat–soybean, double‐crop system
Abstract Long‐term agricultural sustainability and productivity are controlled by the integrative effects of different management practices on the soil. Many Arkansas producers use the double‐crop system to grow soybeans [Glycine max (L.) Merr] and wheat (Triticum aestivum L.). The objective of this...

The objective of this study was to evaluate the effects of agricultural management practices (including residue level, tillage, irrigation, and burning) and soil depth on the change in various soil properties from 2010 to 2020 in a long‐term, wheat–soybean, double‐crop system on a silt‐loam soil (Glossaquic Fraglossudalfs) in eastern Arkansas.
