Cover Crop Seed

Cover Crop Solutions for Western Agriculture

Weaver Seed supplies cover crop mixes and individual species for vineyards, orchards, tree nuts, field crops and other agricultural systems. Choose a proven mix or build a program around your specific soil, crop and management goals.

Cover Crop Mixes

Explore mixes developed for goals including soil cover, nitrogen contribution, biomass, erosion control, compaction management, weed competition, grazing and pollinator support.

Start With the Goal

Choose Cover Crops by What You Need Them to Do

Species selection should follow the agronomic objective. Different combinations provide different levels of biomass, rooting, nitrogen, ground cover and seasonal performance.

N

Nitrogen Contribution

Legume-based options can contribute nitrogen while adding living roots and residue to the cropping system.

Biomass & Soil Cover

Cereal and mixed-species programs can build residue, protect the soil surface and add substantial seasonal growth.

Compaction & Rooting

Deep and varied rooting systems can help improve soil structure and create channels through the soil profile.

Erosion Control

Rapid establishment and dense ground cover help protect exposed soil from wind and water movement.

×

Weed Competition

Fast-growing, competitive species can occupy space and reduce opportunities for unwanted vegetation to establish.

Pollinators & Habitat

Flowering species can add bloom periods and habitat value while still contributing to broader cover crop goals.

Single Species

Build your own cover crop program or select individual species for a targeted agronomic objective.
