Inaccuracy in agricultural chemical application causes increased production costs and releases unnecessary pesticide and fertilizers into the environment. application control is primarily a manual operation and on-the-go adjustment of spray output for spray target or travel speed variation is rare.… More

Anhydrous ammonia (NH3), a heavily used nitrogen fertilizer, is a volatile gas which flashes at -40 F. It is handles as pressurized liquid and difficult to meter accurately and dispense. Its low cost, due to inexpensive energy, has encouraged wasteful over-application rather than investment in… More

This project addresses the increasing demands and need for precise control and reliability in agrochemical application. The ultimate goal of this project is a single-nozzle monitoring and control technology and device. The device will allow individual nozzle resolution on flow rate and spray droplet… More

NON-TECHNICAL SUMMARY: Agricultural spray equipment operators typically cannot monitor all nozzles along the boom. Clogged or malfunctioning nozzles produce undesirable spraying results. This project is designed to lead directly to a useful product, namely, a single-nozzle monitoring unit for… More

Application of agrochemicals is essential to U.S. production of food, fiber, biofuels and ornamentals. However, it can also create environmental contamination if pesticides reach non-target areas through airborne displacement of spray, i.e., "spray drift". Drift is a concern for agriculture,… More

Typical agrochemical sprayers use nozzles to atomize a liquid stream into droplets; these droplets then travel to the target. Nozzles may be selected to provide a range of droplet sizes, spray distribution patterns, and flow rates for a desired liquid material application. Spray distribution,… More
