Louisiana State University AgCenter. 3924. Interpretive Summary: Technical Abstract: Cover crops serve the primary purpose of providing soil surface cover to protect soil from erosion. Research has also demonstrated a variety of secondary benefits depending on the type of cover crop used. Secondary benefits include scavenging nutrients (in particular N) from the soil, suppressing weeds, supporting diverse microbial communities, stabilizing soil, and increasing soil organic matter. Legumes have the potential to form symbiotic relationships with bacteria in the soil, allowing them to turn N from the atmosphere into a plant available form of N. The selection of type and species of cover crop should be based on the needs of the producer. Cool season grasses evaluated included Black ‘Cosaque’ Oats, Bob Oats, Cereal Rye, Triticale, and Wheat. Cool-season annual grass cover crops should be seeded at a rate of 60 – 90 pounds bulk seed per acre. This includes an optimum rate of 60 lbs/acre for drill-seed, and up to 90 lbs/acre for broadcast. |
