My Number One Resource for many years has been ATTRA, National Sustainable Agriculture Information Resource, www.attra.ncat.org. Solid useful info on a range of topics. Very helpful people. Toll-free hot-lines in English and Spanish. Hundreds of helpful publications. Newsletters. Look also on their site for SIFT, (Small-Scale Intensive Farm Training Program) for new farmers. Here’s ATTRA’s pest management page.
Fast becoming another favorite of mine is the newer and rapidly growing eOrganic, the Organic Agriculture part of the Cooperative Extension System.
Many state Extension Services have good websites. Some have particular strengths: Our own Virginia Tech has lots about vegetables and diseases and pests (not necessarily organic). For locally relevant information, start with your local Extension Office after the EOrganic one. Then prepare for global warming and try one south of you. Cornell is good on fruit and Cornell Plant Pathology runs the Vegetable MD online. North Carolina has good info for commercial growers of vegetables, fruits and flowers, including some publications specifically on organic methods. They also have publications geared more towards home gardeners. And they have another of my favorites: Debbie Roos’ site Growing Small Farms.
Southern Sustainable Agriculture Working Group has produced a series of Virtual Farm Tour DVDs. The series is called Natural Farming Systems in the South.
Sustainable Agriculture Research and Education (SARE) Grants and information, including free downloads of several really good books such as Managing Cover Crops Profitably. Click on the Learning Center tab.
