What counts as full fertilisation

Ordinary arable crops normally accept two fertiliser stages, and there must be a crop growth stage between the two applications. Grass is normally a one-stage exception. Manure/slurry equipment may offer double application rate, trading working speed for reaching full fertilisation in one pass.

Choose the nutrient source

Solid fertiliser uses a spreader; liquid fertiliser/herbicide-capable equipment uses a sprayer. Manure, slurry and digestate use their dedicated applicators. Oilseed radish can supply a fertiliser stage when it is grown and cultivated into the soil.

Avoid wasting product

Check the fertilisation map/field info before every pass. Do not cover already fully fertilised ground. If crop destruction is enabled and the crop has emerged, use a suitable narrow-tyre tractor where possible.

Procedure

1. Check current fertilisation state.
2. Choose solid, liquid, manure, slurry/digestate or an oilseed-radish route.
3. Fill the correct applicator.
4. Set an appropriate working width/rate if the machine supports it.
5. Apply the first stage evenly across the field.
6. Wait for at least one growth-stage change before the second ordinary fertiliser pass.
7. Apply the second stage only to areas that still need it.
8. Confirm the field is fully fertilised before harvest.
