Follow up mineral concentrates

The use of mineral concentrates (obtained from manure) instead of chemical fertilizers can relieve the pressure on the manure market. Additional research on the use of mineral concentrates is desirable.


The agronomic, economic and environmental impacts of the production of mineral concentrate and its use as mineral fertilizer were examined in a pilot in 2009 and 2010. In this pilot, the mineral concentrates were applied as fertilizer above the application standard for manure, but within the nitrogen application standard of the Nitrates Directive. The research data will serve for consultation with the European Commission on a possible permanent permission to use of mineral concentrates as replacement of mineral fertilizers. Probably the European Commission has question which needs research to be answered.
