Unintentional Overfertilizing
As the nutrients (N, P2O5 and K2O) contained in the manure has been underestimated, too much nitrogen is applied on the field.
The respective cost of overapplied fertilizer can be saved!
Target rate for Nitrogen:
kg/ha
The saving per hectare if fertiliser is not overapplied
Lost crop yield from underfertilizing
As the nitrogen content in the manure has been over estimated, not enough nitrogen has been applied in the field.
As a result, not enough nitrogen is available to crops, which leads to a reduced yield potential.

25% Overfertilisation:Your savings in the first section of the field:
Calculated for 100% of the area / volume applied (theoretical value)
Calculated for 25% of the area / volume applied (realistic value)
50% Fertilisation on target
25% Potential crop yield loss: Your potential crop yield loss in the third section of the field:
Calculated for 100% of the area / volume applied (theoretical value)
Calculated for 25% of the area / volume applied (realistic value)
Total benefit = Mineral fertilizer savings + Increased Crop yield
When you apply one or more tankers on a field you’ll always have both scenarios of over- and underfertilisation. They occur not at the same point of time, but in different spots of the field. Below table sums up your total savings over the course of a hectare.

Exact N-application according to target rate
Volume applied (m3/ha)
N applied (kg/ha)
Both values (nitrogen applied in kg/ha and volume applied in m3/ha) are measured simultaneously at the same pass over the field. The target rate for nitrogen was set to 40 kg/ha (right hand side). In order to achieve this with the inhomogeneous manure the volume applied had to be adjusted significantly to achieve the constant N application (left hand side).
