Boom sprayer calibration using conventional methods (catching flow for certain time or distance) for large (60-90 ft; 54-72 nozzles) boom sprayers can be a time-consuming process. This short publication outlines steps to take to verify nozzle output and calibrate a boom sprayer, including tables with useful information on flow rates at multiple speeds for two common nozzle spacings and an equation for calculating rates if needed.

Georgia ranks in the nation’s top 10 in cowpea (southern pea, Vigna unguiculata) production, with estimates of more than 4,900 acres grown in approximately 49 of 159 counties in the state in the 2014 production season. Colquitt County, located in southwest Georgia, leads the state in production with 1,900 acres. This cowpea crop profile is the first in the Southeast United States and will support cowpea growers, pest manager, and state research and Extension grant proposal applications.

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.

As farmers and farm advisers, you make many management choices during a growing season. For example, you may have to decide which cultivar to plant, which herbicide to use, how frequently to apply a fungicide, and what rate of nematicide to use. Often the information needed to make the best decision is available to you, but when it is not available you can frequently compare the options by conducting your own small experiments. Your experiments can be just as valid as any university study if you follow a few important principles of experimental design.
