What is the role of cover crops?

A cover crop slows the velocity of runoff from rainfall and snowmelt, reducing soil loss due to sheet and rill erosion. Over time, a cover crop regimen will increase soil organic matter, leading to improvements in soil structure, stability, and increased moisture and nutrient holding capacity for plant growth.

What cover crop is best?

Cover crops that provide good cover and a dense root system help stabilize soils and combat erosion. Clovers, annual ryegrass, Austrian winter peas, crown vetch, sudangrass, sorghum-sudan hybrids, rapeseed, mustards, and cowpeas are good cover crops for erosion protection.

How do cover crops increase soil fertility?

Cover crops are able to increase soil organic matter by protecting the soil surface from erosion, adding biomass to the soil (especially below the soil surface), and creating a habitat for microorganisms like fungi that contribute to the soil biology and provide more pathways for nutrient management in the soil …
