If participating in a cost share program, check for specific required planting dates and rates. If used for forage/grazing increasing seeding rate is recommended. Success of overseeding or aerial seeding after main crop maturity and before harvest is dependent on rainfall and although it can work well, it is usually less dependable than drilling or soil incorporation of seed. Do not save patented seed. When interseeding, time seeding to match appropriate crop growth/maturity. If planting in 15 or 30in rows, use the low end of the drilled seeding rate. If the system is organic, be careful to use an OMRI certified inoculum;
Follow NRCS guidelines for cover crop termination dates for crop insurance. If terminating with only tillage, multiple passes often required. May be difficult to control in an organic system due to lack of certified herbicides and difficulty terminating via tillage. can reseed if maturity is reached
Total N not N fertilizer replacement. Dry matter highly dependent on planting and termination date and precipitation. Non host for sugarbeet cyst nematode and a poor host for soybean cyst nematode.
Good for underseeding
Easy to kill by tillage or mowing
Small seeded legumes are not very competitive with weeds when seedlings.
Entire growing season required to attain very good subsoiling. N production is dependent on length of growing season in the spring
Non host for sugarbeet cyst nematode and a poor host for soybean cyst nematode.
Good for underseeding
Entire growing season required to attain very good subsoiling.
Host for root knot nematode, soybean cyst nematode, and Penetrans Root-Lesion Nematode.
small seeded legumes are not very competitive with weeds when seedlings
may cause bloat when grazed
