Annual Ryegrass - p74

• Broadcast 10-40 lb/A
• Crosspollinates with perennial ryegrass and turf-type annual ryegrass
• Good grazing
• Heavy user of moisture and N
• Can become a weed - do not let it set seed
• C:N = 25-55

Hairy Vetch

• Excellent N provider (to following crop)
• C:N = 8-15
• Moisture-thrifty
• Scavenges P
• vetch/rye mix at 15-25:40-70 lb
