Rye cover crop boosts soil health in cotton systems, aiding sustainability.
A long-term study found that using a no-till system with a rye cover crop in cotton fields can improve soil health. The cover crop helped lower soil nitrate levels during its growth season and increased soil organic carbon in the top layer. This system also improved soil infiltration and reduced compaction, especially in the subsurface layers. These findings suggest that adopting conservation practices like no-till with cover crops can benefit soil quality in cotton fields, particularly in semiarid environments.
