Book Description
Cover crops slow erosion, improve soil, smother weeds, enhance nutrient and moisture availability, help control many pests and bring a host of other benefits to your farm. At the same time, they can reduce costs, increase profits and even create new sources of income. You¿ll reap dividends on your cover crop investments for years, since their benefits accumulate over the long term. This book will help you find which ones are right for you. Captures farmer and other research results from the past ten years. The authors verified the info. from the 2nd ed., added new results and updated farmer profiles and research data, and added 2 chap. Includes maps and charts, detailed narratives about individual cover crop species, and chap. about aspects of cover cropping.

Book Description
The third edition of a standard resource, this book offers a state-of-the-art, multi-disciplinary presentation of plant roots. It examines structure and development, assemblage of root systems, metabolism and growth, stressful environments, and interactions at the rhizosphere. Reflecting the explosion of advances and emerging technologies in the field, the book presents developments in the study of root origin, composition, formation, and behavior for the production of novel pharmaceutical and medicinal compounds, agrochemicals, dyes, flavors, and pesticides. It details breakthroughs in genetics, molecular biology, growth substance physiology, biotechnology, and biomechanics.

Book Description
This book provides a global review of the mechanisms, incidence and control measures related to the problems of soil compaction in agriculture, forestry and other cropping systems. Among the disciplines which relate to this subject are soil physics, soil mechanics, vehicle mechanics, agricultural engineering, plant physiology, agronomy, pedology, climatology and economics.The volume will be of great value to soil scientists, agricultural engineers, and all those involved with irrigation, drainage and tillage. It will help to facilitate the exchange of information on current work throughout the world, as well as to promote scientific understanding and stimulate the development, evaluation and adoption of practical solutions to these widespread and urgent problems.

Book Description
In the past 10 years, there has been a resurgence in interest in soil management and conservation of the soil resource. With the knowledge we have accumulated in the past 100 years, there is the possibility of developing new and innovative ways of effectively managing the soil. The emphasis on sustainable agriculture requires that we understand how to utilize the soil as a viable living resource. To meet the world demand for food within the next 50 years requires a healthy and strong soil resource which can sustain production. With the dedication of the National Soil Tilth Laboratory in 1989, it was decided that one contribution the laboratory could make to agri cultural science would be to foster an exchange of information on soil management. The focus of that interchange centers on long-term soil management. If we are to fulfill the goals of sustainable agriculture, environmental quality, and feeding the world, there will have to be an increased understanding of how to effectively manage the soil. Long-term soil management requires integrated and interdisciplinary research to bring all of the information together in terms which would be applicable to all soils. To accomplish this goal a workshop is held each year, with the exchange of information focusing on a single topic within the framework of developing effective strategies for long-term soil management. With the forum to focus on an individual theme each year, the theme for the initial workshop was "Limitations to Plant Root Growth.

Book Description
Mr. Faulkner’s masterpiece is recognized as the most important challenge to agricultural orthodoxy that has been advanced in this century. Its new philosophy of the soil, based on proven principles and completely opposed to age-old concepts, has had a strong impact upon theories of cultivation around the world. It was on July 5, 1943, when Plowman’s Folly was first issued, that the author startled a lethargic public, long bemused by the apparently insoluble problem of soil depletion, by saying, simply, “The fact is that no one has ever advanced a scientific reason for plowing.” With the key sentence, he opened a new era.For generations, our reasoning about the management of the soil has rested upon the use of the moldboard plow. Mr. Faulkner proved rather conclusively that soil impoverishment, erosion, decreasing crop yields, and many of the adverse effects following droughts or periods of excessive rainfall could be traced directly to the practice of plowing natural fertilizers deep into the soil. Through his own test-plot and field-scale experiments, in which he prepared the soil with a disk harrow, in emulation of nature’s way on the forest floor and in the natural meadow, by incorporating green manures into its surface, he transformed ordinary, even inferior, soils into extremely productive, high-yield croplands.Time magazine called this concept “one of the most revolutionary ideas in agriculture history.” The volume is being made available again not only because farmers, ranchers, gardeners, and agriculturists demanded it, but also because it details the kind of “revolution” which will aid those searching for the fruits of the earth in the emerging nations.

Book Description
This book is a specialized monograph on soil physical conditions and root-system relations. It attempts to explain the importance of physical properties of soil by showing how they affect root growth and functions; and on the other hand, how roots themselves change their environment. Emphasis is placed on the interactive effects of soil physical factors. An attempt has been made to analyze the possibilities of the root system‘s modification by both soil and plant management.The book is addressed to research workers and advanced students in soil and plant sciences and may also be of interest to agronomists and related specialists.
