Interpretive Summary:

Technical Abstract: Precision agriculture can be viewed as a cyclic process, involving data collection, development of management plans, implementing those plans in the field, and evaluation of the effort. Implementation of precision management plans generally involves some sort of variable-rate application (VRA) technology, where fertilizer or crop protection chemicals are applied differentially according to spatially-variable need across the field. This chapter provides information on the basic concepts and implementation of VRA technology, including the alternative approaches available for both liquid and dry product application. It also provides two case-study examples of operating VRA systems, summarizes the current status of VRA technology and explores possible future trends in the field.
