Cover Crops Increase Soil Health in Semi-Arid Regions

A study published in Agrosystems, Geosciences & Environment showed that cover crops can increase soil health in a semi-arid region. Researchers from New Mexico State University and the United States Department of Agriculture found that cover crops increased the biological health of soils at New Mexico test sites, as indicated by carbon dioxide emissions. The researchers are continuing their work to identify a balance of cover crops for arid regions that can produce nitrogen without increasing carbon dioxide emissions beyond what the cover crop itself can utilize. “Cover crops are a great way to sequester carbon, reduce global warming, and increase agricultural resilience,” says New Mexico State University’s Rajan Ghimire. “But there is still a lot to learn about cover cropping, especially in semi-arid environments.”
