Crimson clover is a southern-US adapted clover that typically winter kills but may, in a warm winter, survive in Wisconsin. Crimson is slightly more tolerant of dry conditions than berseem, but is more sensitive to lower pH.
For fall forage potential, expect 0.5-1 ton of dry matter per acre.
A 30-50 lbs N nitrogen credit is possible for a subsequent crop.However, growth and N accumulation may be limited under dry conditions
Plant annual legumes July 15 to August 15 in southern WI, or until August 5 in the north.
Seeding rate: 15-20 lbs per-acre alone
Depth: ¼ inch.
Innoculate with Rhizobium leguminosarum biovar trifolii (R. trifolii).
Management and termination
None typically needed, will winter kill in most Wisconsin winters
In a cover crop mix
After wheat: Crimson can be mixed with any of the small grain cover crops: 8-10 lbs with 30 lbs per-acre oats or barley.
Research in Wisconsin
This study explored using Berseem and Crimson Clovers after winter wheat.
