Choose Cover Crops by What You Need Them to Do

The best cover crop is not simply the mix with the most species. Species and seeding rates should be selected around the field conditions, available moisture, planting window, termination plan and the functions you actually need.

N

Nitrogen Contribution

Legumes such as clovers, vetches and peas can fix atmospheric nitrogen when successfully inoculated, nodulated and actively growing.

↕

Biomass & Soil Cover

Cereals, grasses and multi-species blends can provide vigorous seasonal growth, soil protection and residue for the cropping system.

↓

Rooting & Soil Structure

Combining fibrous roots, taproots and other rooting architectures can increase the diversity of living roots throughout the soil profile.

≈

Erosion Control

Rapid establishment and dense vegetative cover can help protect exposed soil from rainfall impact, runoff and wind movement.

×

Weed Competition

Fast-establishing, competitive cover crops can occupy available space and resources while providing living ground cover.

✿

Pollinators & Habitat

Flowering cover crop species can add bloom periods and habitat value while contributing to broader soil and cropping-system objectives.

Build a Mix Around the Field

A custom mix should solve a specific problem. Weaver Seed can develop formulations around crop type, planting conditions, management objectives and operational requirements when a standard formulation is not the right fit.

✓
Crop-Specific Programs Vineyard, orchard, tree nut and field-crop applications.
✓
Goal-Based Formulations Build around nitrogen, biomass, soil cover, rooting, erosion, grazing or habitat.
✓
Operational Fit Consider planting method, moisture, termination timing and other field-management constraints.
