Cover crops are an alternative way to manage soil fertility in agricultural systems; they can be a living mulch or incorporated into the soil as a green manure. Sometimes one crop can cover multiple needs.
Florida’s sandy soils tend to have low soil fertility as well as low water and nutrient retention because of their low organic content. Cover crops increase soil fertility by adding organic matter.
Farmers can grow cover crops between crop cycles (such as vegetables) or intercropped among crops (such as ground cover in orchards).
