Do Cover Crops Steal Water? Part 2

This episode of Voices from the Field, continues the discussion between NCAT Sustainable Agriculture Specialist Colin Mitchell and Dr. Alexis Racelis of the University of Texas Rio Grande Valley about the use of cover crops in semi-arid subtropical environments.

While cover crops are heralded as a regenerative agriculture tool to improve soil health, integrating cover crops into farming systems can be challenging in drier climates. Colin and Dr. Racelis discuss whether cover crops even can be detrimental in some scenarios and steal water from cash crops.

In particular, the conversation centers on the Subtropical Soil Health Initiative, a research partnership between NCAT and UTRGV to address soil health challenges in the Lower Rio Grande Valley.

NCAT Soil for Water Project
NCAT is scaling up its Soil for Water project to include livestock producers and farmers across eight states.Soil for Water supports a network of farmers and ranchers who are taking steps to catch and hold more water in the soil through land management practices that improve soil health, reduce erosion, sustain diverse plant and animal life, and filter out pollutants.The project grew out of persistent droughts, which are straining agricultural producers across the country. It combines the use of appropriate technology, peer-to-peer learning, and on-farm monitoring to encourage the adoption of regenerative agricultural practices.The Soil for Water project is about building lasting infrastructure that will make farms, ranches and communities more resilient in the face of persistent drought and other natural disasters across the eight-state project region.
