Also Called: Spring Oats
Type: cool season annual cereal
Roles: suppress weeds, prevent erosion, scavange exess nutrients, add biomass, nurse crop
Mix With: clover, pea, vetch, other legumes or other small grains
If you need a low-cost, reliable fall cover that winterkills, look no further. Oats provide quick, weed-suppressing biomass, take up excess soil nutrients, & can improve the productivity of legumes when planted in mixtures. The cover’s fibrous root system also holds soil during cool-weather gaps in rotations, & the ground cover provides a mellos mulch before low-till or no-till crops.
Affordable Biomass: With good growing conditions & sound management (including timely planting), expect 2,000 to 4,000 lbs of dry matter per acre from late summer/early fall-seeded oats & up to 8,000 lbs per acre from spring stands.
Nutrient Catch Crop: Oats take up excess N & small amounts of P & K when planted early enough. Late summer plantings can absorb as much as 77lbs N/A in an 8-10 week period, studies in the Northeast & Midwest have shown.
Type: cool season annual grass
Roles: prevent erosion, improve soil structure and drainage, add organic matter, suppress weeds, scavenge nutrients
Mix With: legumes, grasses
Erosion Fighter: Ryegrass has an extensive, soil-holding root system. The cover crop establishes quickly even in poor, rocky or wet soils and tolerates some flooding once established.
Soil builder: Ryegrass’s dense, yet shallow root system improves water filtration and enhances soil tilth. Rapid above ground growth helps supply organic matter. Expect about 4,000 – 8,000 lb. dry matter on average with a multicut regimen, climbing as high as 9,000 lb. dry matter average over a full field season with high moisture and fertility.
Weed Suppressor: Mixed with legumes or grasses, annual ryegrass usually establishes first and improves early-season weed control.
Nutrient catch crop: A high N user, ryegrass can capture leftover N and reduce nitrate leaching over winter.
Provided it survives the winter, its extensive, fibrous root system can take up as much as 43 lb. N average, a University of California study showed. It took up about 60 lb. N average by mid-May following corn in a Maryland study. Cereal rye scavenged the same amount of N by mid-April on silt loam soil. Ryegrass works well ahead of no-till corn or soybeans in the Corn Belt, sometimes winterkilling, or spray it for weed-controlling mulch.
