System comparison: phosphate fertilisation from 2016 to 2019


The objective of this project is to develop an efficient, low-loss phosphate fertilising system on land requiring fertilisation using minimum soil tillage. The fertilising system based on mineral fertilisers containing phosphate is aimed at winter wheat and winter rapeseed crops, which are of high market relevance due to the percentage of land that they occupy.

Clarification of the following questions:

  • Is the 'Fertilisation from A/B to C' strategy still justified?
  • Can the efficiency of P fertilisation on P-impoverished soil be increased by precisely placing the fertiliser, thus reducing the amount of fertiliser needed for the optimum yield?
  • What influence does precision fertilisation have on root formation and soil fertility?
