It is common knowledge that food production has to be increased significantly the next decades to feed a still growing global population. The application of all essential nutrients in a sufficient amount, at the right time and the right way is key to produce food in an enough amount and to avoid negative environmental impacts such as leaching, gaseous losses or run-off. The target should be on one hand side the highest nutrient use efficiency possible and the other side safe products regarding organic and inorganic contaminants not only in mineral but also in organic fertilizers.
