A major challenge of the twenty-first century will be to ensure sufficient global food production to cope with the burgeoning world population. Soils, Land and Food is a short text aimed at undergraduates, graduates, agricultural scientists and policy makers which describes how the use of technology in soil management can increase and sustain agricultural production. The book leads the reader through the development of techniques of land management and discusses reasons why some agricultural projects have succeeded while others have failed. It shows how surveying and protecting soils before new land is brought into cultivation, raising soil fertility, increasing inputs and improving economic conditions can all help to increase food production. Particular emphasis is placed on the need for both economic change and technological intervention in developing countries where, in many cases, food production will need to more than double in the next fifty years.

Unbiased in approach, this book discusses the physical and chemical land and soil requirements needed to produce food and how economic, social, and political environments influence agricultural productivity. Presenting an array of soil and land properties and farming methods-ranging from slash and burn to highly technical practices-the author draws on his 40 years of worldwide experience to give readers a glimpse at the historical developments, natural resource concerns, and farming practices impacting human food production today.Presents the basics of how soils and land function and examines the impact of water, temperature and chemical elements on food production using minimal scientific terminology. Moves beyond explaining the physical and chemical requirements of human food production to encompass the economic, social and political factors that impact farming practices and overall productivity. Covers current farming methods being used in other countries, from the recent advances in farming on the poorest soils to the slash and burn farming in tropical jungles. Presents historical data to show how modern practices have reduced the cost of food and the amount of land needed to feed a growing population. Provides a strong foundation and makes later chapters on leaching, ground water contamination, floods and erosion easier to understand. Emphasizes the delicate balance of essential elements from the air and in the soil and presents the basic physical and chemical dynamics of the human food chain.Those looking for an easy to understand introduction to how and why various types of soil and land are used for human food production.

As we enter the last decades of the twentieth century, many persistent and perplexing problems continue to afflict humankind. Thus it is appropriate to address, in a new group of books, two of the monumental issues that haunt people throughout the world. Soils and the Environment by Professor Gerald W. Olson is the first book in this new publish ing program on Environment, Energy, and Society. The purpose of all these books will be to explore the many interrelated facets of these topics and to provide guidance for deal ing with problems and offering ideas for their solutions. Environment and energy are twin problems that occupy what many believe to be opposite sides of a two-headed coin. They are often viewed as being antithetical and incompatible. The various books in this program will try to place in perspective the options that are available to those who design policy and plan and manage societal matters. Typical of books being developed currently are ones on coal resources, environmental geoscience, environmental pollution, land-use planning, nuclear energy, mineral resources, and water resources. However, because soils are at the very heart of civilization and provide the building block for human sustenance, it is fitting to inaugurate this series with Dr. Olson's timely analysis of soils. Unfortu nately, these most vital resources seen. to have low priority in many farming enterprises, urbanization projects, deforestation schemes, and mining and developmental terrain changes.

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. Sustainable Soils discusses: what materials can be added techniques for proper handling of organic matter how much is enough (and how much is too much!) the nutritive value of various forms of organic matter the benefits that can be expected from properly handling and adding organic matter to soil From the Editors: “Sustainable agriculture is not possible without a sustainable soil science, which in turn is largely dependent on organic matter. It is necessary to return large amounts of organic matter to the soil in order to maintain satisfactory crop production. It can be derived from crop residues, cover crops, sods, or various wastes, such as manures, sludges, and composts. This book details the benefits of various forms, and how each should be handled for maximum returns.”
