Cover Crop Options for Hot and Humid Areas
A Texas A&M AgriLife Research-led team is releasing the results of a study that showed winter wheat is a feasible cover crop for Rolling Plains cotton production. Under the simulated conditions of the study, the winter wheat cover crop did not substantially affect soil moisture or cotton yield in the subsequent cotton crop. The team compared simulated water-balance components, including transpiration, runoff, soil evaporation, mulch evaporation, drainage and change in soil water, under dryland and irrigated cotton systems with and without cover crops, over a 15-year period. The researchers say their future efforts will focus on better quantifying the soil and water conservation effects of cover crops for the region by identifying ideal cover crop termination dates and assessing the effects of cover crops on carbon and nitrogen balances in cotton production systems.
