08 NITROGEN-FIXING COVER CROPS Crimson Clover Hairy Vetch* Winter annual, viney cover crop legume with purple blossoms and compound leaves. Produces exceptional biomass and can be a heavy N-fixer (up to 100+ lbs N/ acre at flowering). Improves soil structure, scavenges P, and competes very well against early season weeds. Can winterkill if planted past recommended dates. • Best fall-planted legume for nitrogen fixation in the upper-Midwest • We recommend companion seeding with oats, winter rye or another nurse crop to increase chances of winter survival • Produces hard seed; control plant before seed set. Do not seed vetch into small grains if harvesting for marketable grain. Vetch seed is hard to separate from small grains • Hairy vetch is very viney. It can clog harvest machinery, mowers and rotary tillage implements Planting Date: August 1st - October 15th Seeding: 25-35 lbs/acre Conventional ____________ $1.60/lb $80.00/50lb bag Organic ________________ $2.00/lb $100.00/50lb bag Purple Bounty Hairy Vetch NEW! • New winterhardy, early maturing hairy vetch variety form USDA • Selected for high nitrogen fixation potential and increased biomass • Flowers two weeks earlier than common hairy vetch making it ideal for rotations in the upper-Midwest Planting Date: August 1st - October 15th Seeding: 25-35 lbs/acre Conventional ______________ASK/lb $110.00/50lb bag Organic __________________ASK/lb $110.00/50lb bag Austrian Winter Peas* • Viney, fall-seeded, winter annual legume excellent for use as cover crop or forage crop • Can produce up to 1-2 tons dry matter/acre and fix 90-150 lbs N/acre • High quality forage with a protein content of 14% to 20% • Not reliably winter hardy in MN/WI/SD, plant early in the season with a nurse crop to ensure best chance of survival Planting Date: August 1st - September 15th Seeding: 50-100 lbs/acre Conventional _______ $34.00/50lb bag Organic ___________ $42.00/50lb bag Common Vetch* • Viney legume that is an annual in the upper Midwest with pea-like flowers and compound leaves • Good growth for cover cropping if seeded early in the fall, excellent candidate for aerial application • Less winterhardy than hairy vetch; will winterkill in the upper-Midwest • Good forage quality and widely adapted Planting Date: August 1st - September 15th Seeding: 50-60 lbs/acre Conventional ____________ $1.00/lb $50.00/50lb bag Organic ________________ $1.50/lb $75.00/50lb bag Crimson Clover* • Rapidly growing warm-season cover crop clover • Seed as early as possible in the fall for maximum growth and biomass accumulation • Commonly used legume component in cover crop blends • Later seeding into September will result in less growth before freeze up Planting Date: June 1st - September 15th Seeding: 12-25 lbs/acre Conventional _______________ $1.24/lb $62.00/50lb bag Berseem Clover* • Fast-growing summer annual legume • Will produce good amount of biomass quickly and fix up to 100 lbs N/acre at flowering • Slightly more cold tolerant than crimson clover Planting Date: May 15-August 30 Seeding: 12-15 lbs/acre Conventional _______________ $2.12/lb $106.00/50lb bag Balansa Clover • Quick establishing, cool season, annual legume with hollow stems • Good biomass accumulation and N-fixation potential • More cold tolerant than crimson clover; can potentially overwinter • Potential early fall cover crop option after silage corn, small grains or early soybeans Planting Date: July 1st-September 1st Seeding: 5-8 lbs/acre Conventional _______________ $2.50/lb $125.00/50lb bag Spring Peas* • Good legume option for early spring or fall cover cropping • Excellent forage quality for grazing or cut forage in the fall or spring; best companion seeded with a small grain for optimum tonnage • Peas need to be drilled or planted, not broadcasted Planting Date: August 1st - September 15th Seeding: 100-200 lbs/acre Conventional _______ $19.00/50lb bag Organic ___________ $26.00/50lb bag Lentils* • Shor
