Playas are depressional geomorphic features on the U.S. High Plains. About 20,000 Southern High Plains playa wetlands serve as runoff catchment basins, which are thought to be focal points of Ogallala aquifer recharge. Sediments in playas can alter b

Sulfate (SO4) is one of the most important anions in soils and groundwater in semiarid regions, including west Texas. Crops9 sulfur (S) requirement is about 10% to 20% of the nitrogen requirements. However, there is far less information on soil test

A greenhouse experiment was conducted to determine the effect of rice straw residue on growth and uptake of added 15N‐labeled ammonium nitrogen (NH4‐N) (3% 15N abundance at the rate of 150 kg N ha−) by rice in Crowley silt loam soil (Typic Alba
