6000 Soil Sampling for Precision Management of Crop Production | UGA Cooperative Extension

While site-specific soil sampling can improve field management, it must be accompanied by the conscientious collection and analysis of data. The new technologies that have elevated precision agriculture into the forefront of farm management cannot offset poor data collection and soil-testing techniques. Inaccurate data on soil properties will inevitably lead to improper management decisions. This bulletin addresses three primary factors that can affect the precision management of soil fertility: 1) collecting proper soil-sample cores and the consequences of improper soil sampling, 2) breaking the field into smaller management areas, and 3) differences in test results and recommended application rates between soil-test laboratories. A step-by-step procedure is then presented on how to use variabl e yield goals to develop field maps showing variable application rates o f fertilizers and lime.
