Project Title

Alternative phosphorus fertilizers (P-recyclates) to increase the yield of legumes and cereals in organic farming

Project description

Recycled fertilizers containing phosphorus could replace the controversial rock phosphates in organic farming. Some products from wastewater treatment (recycled P fertilizers) have already been tested for their effect, but not yet in practice in the field under organic farming conditions. The phosphorus must be available to plants during crop rotations common in organic farming. Plant availability is often not given with rock phosphates and is therefore a problem for sufficient yields. In this project, different methods for the application of such new recyclate P fertilizers under organic farming conditions are tested. The fertilizing effect will be investigated on three practice farms with different placements of the fertilizers. The aim is to establish the recyclate P fertilizers in an innovative overall concept that makes sense for ecological crop rotations. The innovative overall concept is to be tested for its effectiveness, economic efficiency and sustainability. The findings are intended to offer solutions to challenges in organic farming, especially with regard to efficiency per acreage. Project results will be communicated to farmers in special workshops and at field da
