Integrative Precision Agriculture Resources

RevisedSome 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.

RevisedBoom 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.

The lack of proper planter setup and maintenance results in common planting mistakes that affects crop stand and yield every year. Growers can easily avoid these mistakes by following a few simple steps at the beginning of the planting season to ensure proper planter setup for maximized field performance. This simple and easy-to-follow checklist provides tips on how to properly set up different planter components to achieve a high and uniform stand establishment across the field. The checklist also includes a visual to identify the components available on a typical row-crop planter.

RevisedThis publication provides information on pulse width modulation (PWM) technology including its working principle, components, benefits, and best management practices for its optimal utilization on agricultural sprayers. Pulse width modulation technology was developed to overcome pressure variation issues, as the flow rate is varied by changing the cycle of the electronically actuated solenoid valves while the system pressure remains constant throughout the boom.

Applicators used in granular applications should be calibrated to ensure uniformity and accuracy. An accurate and uniform application can reduce the quantity of an active ingredient required for a given degree of control.

This report provides research and extension results for trials conducted by the University of Georgia Vegetable Team and its collaborators in the 2024-2025 growing season. Management of diseases is necessary to protect crops against disease pathogens and reduce their spread in vegetable fields. This study aims to detect Phytophthora blight severity, a major disease affecting pepper plants, using drone technologies. Contributing authors include county and regional faculty as well as specialists from UGA’s horticulture, plant pathology, crop and soil sciences, and entomology departments. All research has been supported by the Georgia Commodity Commission for Vegetables.
