Dormant Seed Cereal Rye
Posted: November 20, 2015
When is it too late to seed a cover crop? “Dormant” seeding may be the way to go. Soil specialist, Sjoerd Duiker, defines dormant seeding as follows. Late in the fall, a cover crop of rye or wheat can still be planted using ‘dormant seeding.’ Dormant seeding means that the seeds are in the soil but may not germinate or emerge until early spring. However, by planting time in the spring these cereals may be 6 to 12 inches tall. It is different from ‘frost seeding’, which takes place in the late winter.
If a recommended fall deadline for cover crop planting is not met, dormant seeding still may be a good choice, although planting cover crops earlier for living cover in the winter is preferable. Duiker particularly encourages farmers to use dormant seeding after soybean harvest. A recent statistic suggests that few soybean fields are followed by cover crop. Considering that soybeans are a low-residue crop and the residue disappears quickly in the spring, dormant seeding is a good alternative to not planting a cover crop at all.
