Oekoeffiziente Duenger - Entwicklung zur Minimierung der Stickstoffemissionen in Wasser und Luft Schlussbericht

Feeding the world's population today is due to the use of mineral fertilizers in agriculture. Usually, mineral fertilizers supply nitrogen in form of nitrates which can be leached into the ground water or (after reduction) get lost into the atmosphere as gaseous nitrogen compounds (e.g. N_2O). These losses are on the one hand of ecological concern and on the other hand cause reduced agricultural yields. The development of ecoefficient fertilizers aims at an increase of fertilizer use efficiency and at the same time at a reduction of the ecological problems of nitrogen fertilization. Within the scope of this research and development project new nitrification inhibitors, slow release fertilizers and biodegradable materials as fertilizer coatings were investigated with regard to their chemical, technical and agricultural potential. A new nitrification inhibitor has been developed and already introduced into the market. New slow release fertilizer and coating materials show promising perspectives for a further generation of ecoefficient fertilizers.
