Product Description

Intensive agriculture has adequately met food production needs in the United States, but not without some negative impacts.  Many soils in the United States have lost between 30 and 50 percent of the soil organic matter (SOM) present at the start of agricultural production.  An extreme case is the organic soils of south Florida, where drainage and intensive tillage have caused loss of SOM that has resulted in three meters of soil subsidence.

Written by soil scientists with decades of practical experience, Sustainable Soils: The Place of Organic Matter in Sustaining Soils and Their Productivity shows the importance of organic matter in maintaining crop production.  The addition of organic matter to soil is covered in great detail.  This book 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.

In addition, this book stresses the necessity of combining the addition of organic matter with reduced tillage and added chemicals.  Photographs, tables, and figures, as well as appendices containing common and botanical names of plants, symbols and abbreviations found in the text, and useful conversion factors and data help to bring the information into focus quickly and efficiently.

Contents:  Intensive agriculture & food production, Organic matter (OM), OM as a source of nutrients, Physical qualities, Biological effects of OM, Adding OM, Adding OM not grown in place, Placement of OM, Conservation tillage, Changes brought about by conservation tillage, Combining OM additions with conservation tillage, Summary, 3 Appendices: 1. Common & botanical names of plants, 2. Abbreviations & symbols used in this book, 3. Useful conversion factors & data, Bibliography.
