Sudangrass (Piper)
Sudangrass is a super fast growing, fine stemmed warm season annual grass. If summer weed suppression was the goal, this would be one of the best species to accomplish that. Sudangrass is commonly crossed with sorghum to make sorghum-sudan which Takes the fast, tall growing, fine stemmed traits of sudangrass and combines it with the wider leaf and oftentimes higher forage quality of sorghum. For the best grazing digestibility, a BMR (brown midrib) sorghum sudan is usually used which has less lignin.

Spring Oats (Rushmore)
Spring oats are an excellent choice for quick ground cover in the spring or fall. Rapid growth aids in stabilizing disturbed or bare soil from environmental conditions. Spring oats make a great addition to any spring grazing or forage mix providing ample tonnage for your livestock. Oats can be easily chemically terminated and fall plantings commonly winterkill. Residue from oats suppress winter annuals and protect the soil throughout the winter and will decompose rapidly in the spring. Allelopathic chemicals released by the decomposing residue suppress weed germination for a few weeks. The high quality oat forage is more palatable than rye or wheat. Also, oat is less prone to insect problems than either wheat or barley.

Sweet Clover (Yellow Blossom) - OMRI Inoculated
Yellow blossom sweetclover is not a true clover but is probably more closely related to alfalfa. Sweetclover leaves look much like alfalfa, but the margins of alfalfa leaflets are serrated only on the tips. Sweetclover leaflets are serrated around their entire margin. It is typically a biennial, grows 2-6 feet high, and as the name implies, produces yellow flowers. When compared to the white flowering types of sweetclover, yellow blossom blooms roughly 2 weeks earlier and also matures earlier, usually grows less upright, possesses finer stems, and is less productive and less winter-hardy. However, yellow blossom sweetclover persists better in pastures and tolerate adverse conditions better than white varieties. In temperate climates with mild summers it can survive and thrive through a second year of production. Yellow blossom sweetclover adds lots of nitrogen and organic matter to a system.

Annual Ryegrass (KB Supreme) - Diploid
Extending the grazing season while protecting and building the soil is a great benefit of this species. The biomass N content can range from 1.3-2.4% and varies depending on the amount of residual N left from the previous crop. Reports of annual ryegrass having the potential to scavenge up to 200 lbs of residual N/A/yr have been recorded. Ryegrass can be very successfully broadcast into established row crops. Winter killed ryegrass can still provide weed suppression, soil protection and trap residual N until spring. Ryegrass attracts very few pest insects that could pester the next crop. With lower needed seeding rates per acre means you will spend less of freight an your applicator can remain in the drill or in the air longer. I like the deep roots of annual ryegrass but when considering it for more northern area, it must be established prior to hard freezing in order to have the best chance of winter survival. keith@greencoverseed.com

Red Clover (Blaze) - OMRI Inoculated
With similar forage yields, crude protein and better digestibility when compared to alfalfa, red clover can be an excellent forage alternative to add to your operation. You can harvest your first cutting 60-70 days after a spring seeding and on every 30-35 day intervals after initial harvest. With its vigorous spring growth, this clover has the capability of suppressing weeds. Red clover is less invasive than white clover because of its shorter life span and the lack of rhizome or stolon rooting structures. It's deep taproot can extend up to 3ft into the soil profile and finer rooting structure in the top 5" can really aid in breaking up compacted soils. Red clover flowers are known to attract many pollinator and beneficial insect species. If P leaching is a concern, red clover has been observed to leach only 1/3-1/5 the amount of P as ryegrass or radishes. Learn more about Blaze Red Clover here.
