Annual Ryegrass
Annual Ryegrass does well at scavenging nitrogen and preventing erosion. Its large root system makes annual ryegrass excellent at building healthy organic matter in soils, penetrating subsoils, and loosening topsoil. Does well in a mix with oilseed radish and/or crimson clover and is a good choice for planting after early soybeans or silage corn (August 1-September 30). Oilseed Radish Oilseed radishes are excellent subsoilers due to their large tap roots. They are also very effective nitrogen scavengers and work well when planted with a nitrogen source. Oilseed radishes can also serve to build organic matter in the soils, loosen topsoils and fight weeds, but need to be planted earlier in the season (August 1-September 30). Oilseed radishes winter kill and work well in a mix with a grass and a nitrogen source. Note: Oilseed radishes release a noticeable odor when decaying. Crimson Clover Crimson clover is an excellent nitrogen source and a soil builder. It is also good at loosening topsoil and preventing erosion. It grows rapidly, winter kills, and is a good choice mixed with oilseed radish and/or annual ryegrass. |
Cereal Rye
Cereal Rye is excellent at fighting weeds, preventing erosion, loosening topsoil, building soil and scavenging nitrogen. It is also good at penetrating subsoil, though its roots are not as deep as annual ryegrass. Cereal rye is a good choice for late season planting (September 1- November 30) and will leave a noticeable residue. Oats Oats are excellent at preventing erosion and fighting weeds. They also scavenge nitrogen, build soils and loosen topsoils. They winter kill and can be planted August 1-October 20. Austrian Winter Peas Austrian Winter Peas are a good nitrogen source and can also work to loosen topsoil. It grows rapidly and is good for short growing windows. Austrian winter peas can be planted August 1 – October 20. Other species offered: Kale, Purple Top Turnips, Vetch, Rape Seed, Triticale, Buckwheat, and more.
