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.
