Book Description
"Nature works and has been working for a billion and a half years-ever since there were living things on earth. This is important. We talk of controlling nature, but any wise farmer or stockman knows that nature makes the rules for us to learn and follow, if we can. In short, the ecologist is in a position to furnish us, in many ways, models which we can follow in our own operations. Before the prairies were settled, plowed and fenced, wild herds moved back and forth across them, never staying in one place after the grass was cropped too short. These moving herds distributed minerals from their droppings and remains, for it is well-known that wild animals usually maintain a good mineral balance by visiting salt-licks and varying their pasture-grounds. Here in a nutshell is the model for proper use of grasslands. It takes a lot of common sense to get across the information we need. He has it and can put it out so we can all understand it."--Wheelers.co.nz.

Book Description
The contributions in this book describe the role soils play for plant, animal and human health. They show that soil- and human health are intricately connected, because healthy soils produce healthy crops, which in turn nourish humans and animals, allowing for their health and productivity. Soil quality directly influences the quality and quantity of food that can be produced, as soils provide essential macro- and micronutrients and attenuate environmental pollutants. On the other hand, these same pollutants, thus concentrated in soils, may cause soils to become toxic and degraded. Soils (and their crops) may also be responsible for exposure to pests and pathogens, while, at the same time, providing drug substances and may even suppress diseases. Soil quality is vital on a global scale, as more than 800 million people around the world are undernourished, implying that their intake of food is insufficient to meet their daily energy needs, and the deficiency of essential micronutrients is even more widespread. Nearly one third of the world's population is affected by zinc deficiency, while iron deficiency affects nearly 3 billion people. Climate change has been shown to affect animal and human health, and soils are intricately linked to the atmosphere by being both a source and sink of greenhouse gases. Soils are the largest active terrestrial reservoir of organic carbon and its sequestration in soils can be enhanced by improved management practices. The book summarizes the current state of research of these important issues and provides a comprehensive treatise of the global importance of soils to for humankind.

Book Description
During his years as a scientist working for the British government in India, Sir Albert Howard conceived of and refined the principles of organic agriculture. Howard’s The Soil and Health became a seminal and inspirational text in the organic movement soon after its publication in 1945. The Soil and Health argues that industrial agriculture, emergent in Howard’s era and dominant today, disrupts the delicate balance of nature and irrevocably robs the soil of its fertility. Howard’s classic treatise links the burgeoning health crises facing crops, livestock, and humanity to this radical degradation of the Earth’s soil. His message—that we must respect and restore the health of the soil for the benefit of future generations—still resonates among those who are concerned about the effects of chemically enhanced agriculture.

Book Description
Annotation. Successful agroforestry requires an understanding of the complex relationship between trees, crops and soils. This book provides a review of both economic and biophysical aspects of soil use and research in agroforestry, with an emphasis on nutrient-poor forest and savanna soils. Key topics covered include the economics of soil fertility management, cycling of water, nutrients and organic matter, soil structure, and soil biological processes. The book combines synthetic overviews of research results and a review of methods used in research.From the foreword: 2The book is written within a particular context - soil fertility development under agroforestry. At first this may seem very specific and thus limited in appeal and application. But over the last decade or so agroforestry research has been one of the most influential in developing new insights into soil biology and fertility and thus provides a very suitable framework for review of progress. Furthermore the influence of trees on soil is profound and of significance beyond agroforestry systems, so the book is likely to be of interest in the wider spheres of agriculture, forestry and ecological sciences.3 Mike Swift, TSBF, Nairobi, Kenya.

Book Description
This book gathers the latest insights into soil health and its sustainability, providing an up-to-date overview of the various aspects of soil quality and fertility management, e.g., plant-microbe interactions to maintain soil health; and the use of algal, fungal and bacterial fertilizers and earthworms for sustainable soil health and agricultural production. It first discusses the past, present, and future scenarios of soil health, and then explores factors influencing soil health, as well as the consequences of degradation of soil health for sustainable agriculture. Lastly it highlights solutions to improve and maintain soil health so as to achieve greater productivity and sustainability without damaging the soil system or the environment. Soil health is defined as the capacity of a soil to function within ecosystem frontiers, to sustain biological productivity, to maintain environmental quality and to promote plant, animal and human health. Soil health is established through the interactions of physical, chemical and biological properties, e.g., soil texture, soil structure, and soil organisms. Healthy soil provides adequate levels of macro- and micronutrients to plants and contains sufficient populations of soil microorganisms. As a result of the increasingly intensified agriculture over the past few decades, soils are now showing symptoms of exhaustion and stagnating or declining crop yields. Exploring these developments as well as possible solutions based on holistic and sustainable approaches, this book is a valuable resource for researchers in the area of soil and environmental science, agronomy, agriculture, as well as students in the field of botany, ecology and microbiology.

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.
