Case study

Reduction of fertilizer costs by up to 25%

Yields of winter rape higher by 2% while reducing costs by 25%.

Winter wheat yields higher by 4.2% while reducing costs by 11%.

The optical difference between winter rapeseed fields fertilized variably and uniform fertilized fields consisted in the overall alignment of the stands and definitely in the saving of fertilizer, the amount of which was reduced by about 25% compared to the uniform plan.  In wheat, no significant difference is observed, a lower volume weight cannot be excluded due to the overall lower doses of nitrogen.
