General Information Sources

ATTRA (Appropriate Technology Transfer for Rural Areas), the sustainable farming information center funded by the U.S. Department of Agriculture, provides assistance, publications and resources, including sustainable soil management, cover crops and green manures, farm-scale composting, and nutrient cycling in pastures, free of charge. P.O. Box 3657, Fayetteville, AR 72702; (800) 346-9140; www.attra.org

How to Conduct Research on Your Farm or Ranch, an informational bulletin from the Sustainable Agriculture Network (SAN), provides practical tips for laying out a research trial. On-farm research can help you evaluate new practices such as fertilizer rates or cover crop species. Available at: www.sare.org/publications/research.htm

Most state Cooperative Extension offices publish leaflets and booklets on manures, soil fertility, cover crops, and other subjects described in this book. Request a list of publications from your county extension office. A number of states also have sustainable agriculture centers that publish newsletters.

USDA’s Sustainable Agriculture Research and Education (SARE) program studies and spreads information about sustainable agriculture via a nationwide grants program. SARE funds publications through its Sustainable Agriculture Network (SAN), and maintains a database of more than 1,600 projects. For information about publications, funded projects and how to apply for a grant, call (301) 405-3186 or visit www.sare.org.
