  • Cereal Rye (Elbon) Cereal Rye (Elbon)

    Cereal Rye (Elbon)

    Cereal Rye has an excellent fibrous root system that alleviates surface compaction. Rye can be successful planted later then almost any other cover crop due to its low germination and growth temperature requirements. Cereal rye is known for being the best cereal crop at retaining residual N. It's typical for a fall planted cereal rye crop to scavenge on average 25 to 50 lbs of N, with cases scavenging in excess of 100 lbs of N. The vigorous spring growth has successful weed suppression through competition and allelopathic chemicals. Rye can be terminated in the spring through the alternative methods of rolling, mowing, or crimping after boot stage. Rye will out yield any other cereal crops when planted in droughty, infertile, or sandy soils.

  • Radish (Nitro) Radish (Nitro)

    Radish (Nitro)

    Rapid fall growth in short windows, allows radishes to fit perfectly into a traditional corn and soybean rotation. Radish residue breaks down very quickly in the spring, leaving a clean seed bed until early April. The residue has been proven to inhibit small seeded annuals from germinating. Nutrients that were scavenged are readily released back into the soil for the subsequent crop. A field planted in radishes, will allow the soil to dry and warm faster in the spring. The large root channel left behind is rich in nutrients, allows tremendous water infiltration, reduces water erosion, and a path for crops roots to follow through compacted soil layers. During decomposition, radish biofumigates the soil which can reduce pest and nematode populations.

  • Spring Oats (Rushmore) Spring Oats (Rushmore)

    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.

  • Annual Ryegrass (Centurion) - Diploid

    Annual Ryegrass (Centurion) - 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.

  • Smooth Bromegrass

    Smooth Bromegrass

    Smooth brome is a productive, cool season grass with good drought tolerance. It has decent palatability though it is best grazed in a vegetative state. Smooth bromegrass is very aggressive, establishing quickly for a perennial and spreads through rhizomes, making a dense sod. This means it is great for waterways and holding soil on slopes but it can also dominate and even choke out other perennial species. For that reason, it should be used sparingly in pasture mixes, relying on other species which are more palatable and offer better regrowth, but using smooth brome to fill in.
