Variable-rate application (VRA) allows for a prescribed amount of fertilizer based on soil test results, but is generally more expensive than uniform application. This publication explains how geographic data is connected to soil test results and how equipment, a prescription map, and agricultural GIS (geographic information system) software work together in VRA process. Included is a table of available GIS agriculture software.
