Cover crop calculator – Economics

This interactive calculator is a decision-support tool that estimates the costs and benefits of winter cover cropping in almond and processing tomato operations in California’s Central Valley. The tool estimates how much farmers can expect their profits to change after growing winter cover crops for a certain number of years. All values that are used in the calculator are flexible and can be adjusted to match the reality on your farm. The tool was designed for farmers who are interested in growing winter cover crops and who want to understand how long it will for that investment to break even. … Read the rest

Cover Crops Database – UCANR

In an effort to make information on specific cover crop species available and easily accessible, the UC Sustainable Agriculture Research and Education Program created the cover crop database, first released in 1999 (and it remains one of the most highly visited features of UC SAREP’s extensive website). The database contains detailed entries for over 40 commonly used cover crop species. For each crop, a summary of key factors is provided, including: Seed, seedling and mature plant descriptions and pictures Ideal temperature and geographic range Soil, water and nutrient considerations Management details including planting and termination dates, maintenance issues, mowing, … Read the rest
