This script makes it possible to calculate the application rate of liquidmanure, manure, fertilizer, lime, liquid fertilizer and
herbicide to the worked hectare. The application rate is regulated depending on the speed.
This means, no matter what speed is applied, the application rate is always adjusted.
The script installs itself in all vehicles that have the specialization "sprayer", so in all
Slurry spreading devices, syringes, fertilizer spreaders and manure spreaders.
The following application rates are possible:
Liquid fertilizer / herbicide 100 to 800 liters / hectare
Fertilizer / lime 1000 to 9000 liters / hectare
Solid manure 12,000 to 30,000 liters / hectare or 12 to 30 m³ / hectare
Manure 10000 to 45000 liters / hectare or 10 to 45 m³ / hectare
