Jack R. Harlan conceived the prevailing concepts of how the activities of human societies have shaped the evolution of crops used for food, feed, and fiber. Harlan collected and introduced over 12,000 accessions of plants into the United States. The world food supply now depends largely on only 12 to 15 plant species. Erosion of diverse gene sources from ancient landraces continues and more effective use needs to be made of germplasm collections in our gene banks.Also available:Stubble Over the Soil: The Vital Role of Plant Residue in Soil Management to Improve Soil Quality - ISBN 0891181318 North American Agroforestry: An Integrated Science and Practice - ISBN 0891181423The American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America are prominent international scientific societies headquartered in Madison, Wisconsin.

Sunflower is an excellent example of the success story of the 20th Century agricultural research system. By concerted and coordinated efforts of breeders, farmers, commercial enterprises, plant physiologists, entomologists, and agronomists, this crop has increased in acreage, usefulness, and economic importance during this century more than at any other time in history.These successes have resulted from efforts in many nations and by many different disciplines. There have been significant improvements in cultivars available for use, in the development of adapted cultivars for new areas, and in selection for specific properties needed for different end uses. The drought tolerance and deep-rooted habit of this species have enabled farmers in arid areas to have an economically viable alternate crop to incorporate into rotations that improve management options. Sunflower's popularity as a source of food and cooking oil have maintained and diversified the market for its products, especially in recent years.It is appropriate that our new knowledge of this species be integrated with previous knowledge and brought together in one place to provide a landmark in the forward progress of this important crop. This volume provides just such a landmark for sunflower researchers and the sunflower industry both in this country and abroad.

An in-depth look at no-till applications through the eyes of Chilean farmer, Carlos Crovetto. Mr. Crovetto was able to renovate his soils and obtain high wheat and corn yields using no-till and adequate fertilizers. The soil not only recuperated, but became far more productive than the original soil. This book combines a thorough treatment of the science of soil management with many personal experiences. An enjoyable read or great for the classroom, it also includes many color photographs and a glossary.

Stubble Over the Soil: The Vital Role of Plant Residue in Soil Management to Improve Soil Quality

Carlos Corvetto Lamarca

Because of the environmental consequences of past agricultural and forestry practices that focused exclusively on the economic bottom line, the public now demands greater accountability and the application of more ecologically and socially friendly management approaches. Introductory chapters focus on the ecological foundations and the current status of agroforestry. Additional chapters cover technical aspects of major agroforestry practices: windbreaks, silvopastures, alley cropping, riparian forest buffers, and forest farming. The book concludes with several chapters that evaluate these systems, integrate related socioeconomic factors, and explore the future.

Land reclamation, particularly of land disturbed by mining, is a major environmental issue throughout the world. Thirty-eight chapters explore the vast complexities involved in reclamation after large-scale disturbances and provide a broad range of perspectives and examples of reclamation efforts. Readers will find specifics, from mapping minesoil to policy-making, from geochemistry to large-scale topography, from the papermill to oil shale, and emerge with an overall understanding of reclamation strategies and challenges.

Reclamation of Drastically Disturbed Lands (Agronomy, No. 41)

From large-scale installations of riparian buffers to family-scale forest farming, agroforestry is a technology that has truly 'come of age.' Creating consumer markets for forest-grown products, reducing nonpoint source pollution, protecting waterfowl habitat, diversifying small farm operations-these are just a few of the ways agroforestry is moving to the forefront. Agroforestry provides many opportunities to meet the needs of landowners and natural resource professionals while keeping the family farm viable and the environment in which we live healthy. 
The second edition of North American Agroforestry: An Integrated Science and Practice adds to the excitement and builds upon the science. Readers will learn the fundamentals of the main agroforestry practices, with detailed case studies and examples, as well as strategies for addressing the financial viability of new practices and navigating policy. In addition to updating the original topics, this edition includes a discussion of tree-crop interactions, agroforestry product markets and marketing, and wildlife benefits. Each chapter includes a set of study questions. Taken together, these chapters, contributed by recognized authorities in their fields, demonstrate that agroforestry has the potential to advance North America's land stewardship by converting degraded lands, protecting sensitive lands, and diversifying farm and forest production systems.
