Soil Testing: Sampling, Correlation, Calibration, and Interpretation

A special symposium on soil test calibration was held at the August 1975 American Society of Agronomy meeting in Knoxville, TN. The proceedings of that symposium were published in 1977 as ASA Special Publication no. 29 entitled Soil Testing: Correlating and Interpreting the Analytical Results. The impact of the energy crisis of the 1970s, the grain embargo in response to USSR activities in Afghanistan, and other international and national activities all served to put a severe damper on export of U.S. agricultural products. This reduced the markets for agricultural products and the prices received. Environmental pressures have also mounted and there has been public concern for the protection of water quality and prevention of pollution from chemical fertilizers. The net result was a severe economic crisis in agriculture, which has placed increased emphasis on the efficient use of all agricultural inputs, including fertilizer. Soil testing plays a key role in the efficient use of fertilizer and its economic benefit.
