Available Incentive Programs

USDA Advancing Markets for Producers (AMP)

Covers the full cost of the first 10 acres at $375/acre, then an additional $100/acre credit for up to 100 more acres. Applies to perennial cover crop establishment as a climate-smart practice.

Up to $13,750

California Soil Restoration Project (CSRP)

$100/acre recurring annual payment for each year the perennial cover is maintained in place. Stackable with AMP (verify program requirements before combining).

$100/acre/yr

Estimated Agronomic Benefits

These estimates are calculated automatically based on your crop type and county, using data from UC Davis Cost & Return Studies, UC ANR Cooperative Extension, and Oakville Bluegrass Cooperative field research. They reflect conservative mid-range values for established perennial cover crops and do not assume a legume species.

Yield improvement is not included in automatic estimates as it varies widely by operation and soil baseline. You can add a yield benefit percentage in the results section if desired.

Additional co-benefits not captured above: Perennial cover crops improve soil water retention, reduce erosion, support beneficial insects and pollinators, and can improve wine grape quality through reduced vine stress. Carbon sequestration may unlock future carbon credit opportunities through programs like the California Healthy Soils Program.

Data sources: Costs and yields based on UC Davis Agricultural Issues Center / UCCE Cost & Return Studies for California almonds and wine grapes (2019–2024). Cover crop cost of $375/acre for perennial establishment. Program incentives as described by the USDA AMP program and California Soil Restoration Project. Agronomic benefit estimates are indicative only and will vary by operation. This tool is intended as a planning guide — consult your farm advisor and program administrators before making investment decisions.
