Summary

Phosphorus is an essential, non-substitutable nutrient for all living organisms, and global resources are getting depleted. Cycling of nutrients is a main principle in organic farming, which can make P fertilizers recycled from sewage sludge a suitable alternative. Several Recycling P fertilizers from sewage sludge processing, combined with two different Bioeffector products, were investigated for their P availability in pot experiments with red clover and maize. No significant effects could be shown due to Bioeffector applications. Promising effects of Recycling P-fertilizers could be shown concerning dry matter and plant P-uptake for both maize and red clover. Treatments with struvite reached values comparable with the superphosphate control while sewage sludge ash and the pyrolysis-coal performed in the lower range of the unfertilized and Phosphate Rock (PR) control. Remaining products lied in between. Further research on Recycling P-fertilizers is a promising approach in search of an alternative P supply of crops in the future.
