Biological Husbandry: A Scientific Approach to Organic Farming covers a proceeding of a symposium organized by International Institute of Biological Husbandry on August 26-30, 1980 at Wye College in London, United Kingdom. Said symposium aims to promote the scientific development of biological or organic agriculture. The text covers topics such as the assessment of conventional, biological, and integrated agriculture; soil use in temperate climates, organic matter cycles in tropical soils, and plant-microbial interactions; biological pest control, the importance of chemical agents and biotechnology in biological husbandry, and allelochemicals in the future of agriculture. The book is recommended for biologists and agriculturists who would like to know more about the studies in biological husbandry and its implications in the field.

Recent agri-food studies, including commodity systems, the political economy of agriculture, regional development, and wider examinations of the rural dimension in economic geography and rural sociology have been confronted by three challenges. These can be summarized as: ‘more than human’ approaches to economic life; a ‘post-structural political economy’ of food and agriculture; and calls for more ‘enactive’, performative research approaches. This volume describes the genealogy of such approaches, drawing on the reflective insights of more than five years of international engagement and research. It demonstrates the kinds of new work being generated under these approaches and provides a means for exploring how they should be all understood as part of the same broader need to review theory and methods in the study of food, agriculture, rural development and economic geography. This radical collective approach is elaborated as the Biological Economies approach. The authors break out from traditional categories of analysis, reconceptualising materialities, and reframing economic assemblages as biological economies, based on the notion of all research being enactive or performative.

Sustainable agriculture is a rapidly growing field aiming at producing food and energy in a sustainable way for humans and their children. Sustainable agriculture is a discipline that addresses current issues such as climate change, increasing food and fuel prices, poor-nation starvation, rich-nation obesity, water pollution, soil erosion, fertility loss, pest control, and biodiversity depletion. Novel, environmentally-friendly solutions are proposed based on integrated knowledge from sciences as diverse as agronomy, soil science, molecular biology, chemistry, toxicology, ecology, economy, and social sciences. Indeed, sustainable agriculture decipher mechanisms of processes that occur from the molecular level to the farming system to the global level at time scales ranging from seconds to centuries. For that, scientists use the system approach that involves studying components and interactions of a whole system to address scientific, economic and social issues. In that respect, sustainable agriculture is not a classical, narrow science. Instead of solving problems using the classical painkiller approach that treats only negative impacts, sustainable agriculture treats problem sources. Because most actual society issues are now intertwined, global, and fast-developing, sustainable agriculture will bring solutions to build a safer world. This book series gathers review articles that analyze current agricultural issues and knowledge, then propose alternative solutions. It will therefore help all scientists, decision-makers, professors, farmers and politicians who wish to build a safe agriculture, energy and food system for future generations.

It has long been recognized that soil organic matter is the key to soil fertility. As a nutrient store it gradually provides essential elements which the soil cannot retain for long in inorganic form. It buffers growing plants against sudden changes in their chemical environment and preserves moisture in times of drought. It keeps the soil in a friable, easily penetrated physical condition, well-aerated and free draining, providing young seedlings with an excellent medium for growth. But it has another property, the nature and extent of which have been the subject of argu ment and controversy ever since scientists began to study the soil, and that is its ability to affect growth directly, other than by providing nutrient elements. Any one wishing to learn about these effects has been faced with a daunting mass of literature, some confusing, often contradictory, and spread through a multitude of journals. Individual aspects have been covered from time to time in reviews but there has obviously been a need for a modern authoritative text book dealing with the many facets of this subject, so the publication of this volume is timely. The editors and authors are all specialists in their fields, fully familiar with the com plex nature of soil organic matter and with the particular difficulties arising in any study of its properties. Where controversies exist they have presented all sides of the argument and have highlighted areas where further work is badly needed.
