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.

Merging coverage of two increasingly popular and quickly growing food trends, Organic Production and Use of Alternative Crops provides an overview of the basic principles of organic agriculture and highlights its multifunctionality with special emphasis on the conservation of rare crops and their uses. Considering more than 30 disregarded and negle

The tropics are the source of many of our familiar fruits, vegetables, oils, and spice, as well as such commodities as rubber and wood. Moreover, other tropical fruits and vegetables are being introduced into our markets to offer variety to our diet. Now, as tropical forests are increasingly threatened, we face a double-fold crisis: not only the loss of the plants but also rich pools of potentially useful genes. Wild populations of crop plants harbor genes that can improve the productivity and disease resistance of cultivated crops, many of which are vital to developing economies and to global commerce. Eight chapters of this book are devoted to a variety of tropical crops—beverages, fruit, starch, oil, resins, fuelwood, fodder, spices, timber, and nuts—the history of their domestication, their uses today, and the known extent of their gene pools, both domesticated and wild. Drawing on broad research, the authors also consider conservation strategies such as parks and reserves, corporate holdings, gene banks and tissue culture collections, and debt-for-nature swaps. They stress the need for a sensitive balance between conservation and the economic well-being of local populations. If economic growth is part of the conservation effort, local populations and governments will be more strongly motivated to save their natural resources. Distinctly practical and soundly informative, this book provides insight into the overwhelming abundance of tropical forests, an unsettling sense of what we may lose if they are destroyed, and a deep appreciation for the delicate relationships between tropical forest plants and people around the world.

This work powerfully asserts the idea that rather than using pesticides, the key to helping crops resist attacks from pests is to improve their strength through natural processes. Many of industrial agriculture's fundamental principles for fighting disease, in particular the reliance on pesticides and fertilizers, are explained and convincingly challenged and a new set of guiding principles for an ecological agricultural system are presented as a genuine alternative to the widespread use of chemicals.

This new edition of an established title examines the determination of grain crop yield from a unique perspective, by concentrating on the influence of the seed itself. As the food supply for an expanding world population is based on grain crops harvested for their seeds, understanding the process of seed growth and its regulation is crucial to our efforts to increase production and meet the needs of that population. Yield of grain crops is determined by their assimilatory processes such as photosynthesis and the biosynthetic processes in the seed, which are partly regulated within the seed itself. Substantially updated with new research and further developments of the practical applications of the concepts explored, this book is essential reading for those concerned with seed science and crop yield, including agronomists, crop physiologists, plant breeders, and extension workers. It is also a valuable source of information for lecturers and graduate students of agronomy and plant physiology.

Handy for commercial producers as well as backyard gardeners, this classic guide for growers and sellers of niche market produce provides detailed information about growing specialty crops that are growing in popularity among consumers. Includes 63 crop sheets-from arugula to radicchio, basil to thyme, prickly pear to tomatillos, variety and heirloom tomatoes. Includes market information, resources, and a glossary of Asian vegetable names.
