Soil Sampling for Precision Management of Crop Production
(B 1208)
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.
Water Use and Irrigation Management for Vegetables in Georgia: Watermelon (Citrullis lanatus)
(C 1183)
This circular contains the fundamentals of watermelon irrigation scheduling using the crop water demand method. Decisions regarding the timing, frequency, and amount of water required for a crop are some of the most critical factors in vegetable production. There are numerous irrigation scheduling strategies employed by growers, but the crop water demand method of irrigation management is one of the most reliable and precise ways to schedule irrigation. This method adjusts irrigation events using the crop evapotranspiration, or ETc.
