Abstract:
... An interest to grow cover crops is increasing in the semi-arid Texas Rolling Plains (TRP) region, where cotton (Gossypium hirsutum L.) is a major cultivated crop. Under conservation tillage systems, cover crops are expected to enhance ecosystem services, including improved soil health and erosion reduction. However, there is a concern that cover crops could deplete soil water content and affect th ...
