VR Lime Application Based on Soil pH Data

Create a variable-rate lime Rx prescription map from soil pH scans, validate economics, then export as SHP/ISOXML or send to a machine via integrations.

Create a variable-rate (VRA) lime Rx prescription map from soil pH

Turn soil pH data into a machine-ready lime application map (Rx prescription). Use it to apply lime only where ROI is positive.

Economics example (VR vs flat 7,000 lb/ac)

This example compares variable-rate lime against a single flat rate across the field. Use it as a quick sanity check before exporting the Rx.

Item	Value
Field area	33.91 ha
Avg applied rate	6,348.2 lb/ac
Lime price	$0.02 / lb (~$40/t)
Total lime (calc)	523,853 lb
Material cost (field)	$10,477
Material cost (per ha)	~$309/ha
Savings vs 7,000 lb/ac (total)	$441.9
Savings vs 7,000 lb/ac (per ha)	~$13.0/ha
