Soil and your health

"In "Soil and Your Health," eminent health writer and environmentalist Beatrice Trum Hunter discusses the natural resource that grows our fruits and vegetables. The quality of food depends on the quality of the soil in which it is grown. Is organically produced food superior to conventionally grown food? How do earthworms and trace minerals benefit the soil and the food and feed grown on it? How do intentionally applied fertilizers, pesticides, and sludge, as well as inadvertent contaminannt affect soil? Hunter responds to the mounting soil-quality crisis with hopeful answers and measures beginning in our own gardens and farms."--Publisher description.
