Homemade Organic Vegetable Fertilizer

A former history teacher for the last 40 years, Steve Solomon has built his reputation around gardening. The author of "Growing Vegetables West of the Cascades" and "Gardening When It Counts," as well as other books, Solomon's advice for how to care for your vegetable patch is so sound that Cornell University Cooperative Extension offers his recipe for homemade organic vegetable fertilizer as one of its fact sheets for home growers. His concoction is the result of more than 30 years of research and personal experience growing vegetables to feed his family.
