Research has indicated that managing manure as a fertilizer resource for crop production can increase the return to the producer, minimize the pollution potential of animal waste, and enhance the overall production efficiency of a livestock/crop operation. The principal objective of this project was to develop and demonstrate a GPS-equipped liquid manure application system that could become a component of a precision manure management system. A manure spreading device was modified utilizing computer hardware and software (GPS/GIS) to control (on/off) the placement of manure according to predefined environmentally sensitive areas (e.g., wells, streams, setback areas, etc.), and to record and document location (latitude/longitude), date/time, and quantity (volume per unit area) of liquid manure that has been applied to any given area. |
