Soil Sampling for Precision Management of Crop Production
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.
GPS Guidance Options for Forage Systems
Some of the most widely adopted precision agriculture technologies include guidance systems that utilize a Global Positioning System (GPS). Although these technologies are most commonly utilized in row-crop agricultural systems, they also have many potential benefits in forage-based production systems. With so many different options to choose from, it can be a daunting task to determine which technologies are the best fit for a specific farming application and budget. When coupled with a differential GPS system (which are available in various levels of correction accuracy), the accuracy of these guidance systems can be greatly improved. The main goal of this bulletin is to cover the currently available GPS guidance options for forage production systems.
Using SpotOn® Digital Meter for Boom Sprayer Calibration
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.
