Sustainable Soils: The Place of Organic Matter in Sustaining Soils and Their Productivity
Find the right balance of organic matter, tillage, and chemical additives to increase the quality and quantity of crops!
This book shows the importance of organic matter in maintaining crop production. The addition of organic matter to soil is covered in great detail. This book is unique in that it draws on practical farming operations to illustrate many of the points discussed. The senior author has had almost 60 years of experience in solving production problems—many of which have been related to insufficient organic matter.
In addition, Sustainable Soils: The Place of Organic Matter in Sustaining Soils and Their Productivity stresses the necessity of combining the addition of organic matter with reduced tillage and added chemicals. Photographs, tables, and figures, as well as appendixes containing common and botanical names of plants, symbols and abbreviations found in the text, and useful conversion factors and data help bring the information into focus quickly and efficiently. An extensive bibliography points the way to other useful material on this subject.
