W. Shaw Reid
Professor Emeritus of Soil Fertility

803 Bradfield Hall (607) 255-1722 E-mail: wsr1@cornell.edu BS Mississippi State University 1959 MS Mississippi State University 1961 PhD Mississippi State University 1965 Shaw Reid joined the Cornell faculty in 1966 with responsibilities in extension and applied research in soil fertility. He has been the primary contact with the Fertilizer and Lime industry and has served as the Secretary-Treasurer of the Empire State Soil Fertility Association, an association to further education in soil fertility and management agriculture. He served for 11 years as the Departmental Extension Leader. He has spent a sabbatic leave in Hawaii working on lime requirements for tropical soils, and another sabbatic at Oregon State University working on alfalfa fertility and soil testing. In 1990, he accepted the responsibility of Director of the Cornell Nutrient Analysis Laboratories.

Research Program His research is primarily in the area of improving the efficiency of fertilizer and limes for agricultural production and environmental protection. The N contributions from green manures, such as alfalfa sods to subsequent corn crops in New York and in the tropics, has been eventful. For example, an alfalfa sod can supply adequate N to produce a 150 bu/a corn crop the year a sod is plowed. The N contribution decreases to 50-70 pounds/acre in the second year, and 20-40 pounds/acre in the third year. He is Director of the Cornell Nutrient Analysis laboratories, therefore, some research is on analytical methods and soil test correlations for New York and tropical soils. He has the major responsibility, in cooperation with other faculty and staff, for developing fertilizer and lime recommendations for field crops in New York State. He maintains contact and provides information to the Lime and Fertilizer industry. The Cornell Nutrient Analysis Laboratories has two major functions. First, it provides growers with soil testing analyses and nutrient recommendations for economic crop production. Second, the Laboratory provides analyses of soil, water and plant samples for research purposes. As director, considerable effort on methodology, quality control, and other activities is necessary.
