Prescription map
A digital file that provides instructions to agricultural equipment to automatically adjust application rates for seeds, fertilizers, or chemicals across a field.
Также говорят: VRA map, variable rate application map, task map
A prescription map is a foundational element of precision farming. It translates agronomic data, such as soil maps or yield history, into machine-readable instructions that command variable rate application (VRA) controllers in real-time.
By applying inputs at variable rates, farmers can optimize crop input costs and boost yield potential while reducing environmental impact. The map ensures that nutrient-deficient areas receive adequate support without over-applying in high-fertility zones.
Common errors include the use of low-resolution data, failure to verify compatibility between the mapping software and machine consoles, and neglecting to perform a field test to ensure correct task execution.
