"This book, written by soil scientists with decades of practical experience, shows the importance of organic matter in maintaining crop production. The addition of organic matter to soil is covered in great detail. Sustainable Soils: The Place of Organic Matter in Sustaining Soils and Their Productivity discusses what materials can be added, proper handling, how much is enough (and how much is too much!), the nutritive value of various forms of organic matter, and the benefits that can be expected."@en . . . . . . . . . . . . . . . . . .
