Physical investments for innovation and modernization of agricultural enterprises

Under the Rural Development Program POP3 Brabant 2014-2020, concerning measure:
A system for targeted low-emission application of liquid substantial fertilizers in the correct dosage without overlapping in the soil. Systems for measuring the nitrogen content of the applied manure with NIR if this is immediately translated into dosing.
In this way less fertilizer is applied per unit area of the soil and therefore less nitrate is flushed to the bottom layers of the soil and the ground and surface water.

By making soil maps we know the mineral composition of the soil. (Activity 1). By compiling this data, we can mark areas that may require less nitrogen. (Activity 2). Because we apply to manure and directly measure the nitrogen content with the NIRS (Activities 3 and 4), we can analyze at a later stage what the effect of the dosage was in combination with big data.

In this way we get to know the soil better to add less fertilizers and where the software indicates to apply more fertilizer. In this way less fertilizer is applied per unit area of ​​the soil and therefore less nitrate is flushed to the bottom layers of the soil and the ground and surface water. Furthermore, the application techniques are low-emission in the air.

We have chosen to apply variable fertilization to 5 test fields to investigate the effect of different interventions.

Test fields A-D are potatoes, test field E is corn. In total 60Ha.

Test field A Making sense 13Ha: fertilize strips with different dosages of cattle slurry. Measured with NIRS on NPK. Add 70L strips to legs with row fertilization liquid fertilizer.

Test field B For house against forest 12Ha: Whole plot fertilized with 40 cubic meters of cattle slurry, Nir measurements on N, P, K, OS per load. Then applied to legs with row fertilization in both low and high conductivity

Test field C vabor 13 Ha: Variable fertilization test exactly according to conductivity of soil maps. Applied to a strip (high conductivity = high yield potential = more fertilizer in the row

Test field D Van gompel herdersdreef 12Ha: Variable fertilization test with varying fertilization at the same conductivity. One strip applied (high conductivity = high yield potential = shorter planting distance = more fertilizer in the row) 2nd firing applied inversted (high conductivity = high yield potential = wider planting distance = less fertilizer in the row)

Test field E block barn against nut 10 Ha: Maize field, control on phosphate. This field was initially intended for sugar beet, but we eventually sowed corn on it. This makes no difference to the research. Controlled at 50 kg \ N per ha.

We already get positive results from the revenue maps.

The project has been completed and research into precision fertilization continues.
