Planning a Pasture System
• Plant Maturity Determines Forage Quality
▫ Younger plants have high forage quality than older plants

Take Home Points
• Different grasses should be planted in different pastures.
• Plant maturity varies within grass species and between grass species.
• Planting grasses with different maturities increases the time when pastures have the highest forage quality.

How to chose pasture mixtures?
• Start with 3-4 grasses that have different maturities planted with 1 or 2 legumes
• Try specialty pasture plants on a small scale before adding to the whole pasture system
• Identify niches where specialty pasture plants are well suited

What seeding rates to plant?
• 50 to 75 seeds per ft2 are enough to establish forage stands
• Most farmers seed more (100-200 seeds per ft2) “cheap insurance” and “quicker establishment”
• High seeding rates reduce the establishment of some species (often legumes)
