Research need from Focus Group: Study the transition from raw bulk products containing nutrients in variable concentrations and ratios towards tailor-made fertilisers with desired and well-known formulated compositions

This need for research has been identified in FG 19 on “Nutrient recycling”. If you want to know more about it, check the final report of the Focus Group.

Composition of biobased fertilisers are determined by the original streams from which they are produced. Rarely to never the composition of such products will represent an optimal concentration and ratio between N-P-K and other nutrients in relation of the targeted crop requirements. Because of this, there will always be a ‘limiting element’ which determines how much you can supply as based on fertiliser regulations. This in turn will require the other nutrients to be additionally amended. If biobased fertilisers could be adaptable to serve variable crop requirements more directly at the source, being able to supply several nutrients at once in desired ratio, they would become more valuable to end-users who would otherwise need to blend and amend products to meet their specific crop requirements.
