Summary in the original language of the document
Experiments showed higher N efficiencies for stored human urine, digestates and sewage sludge than compost. Additionally, higher contents of ammonium-nitrogen (NH4+-N) and a lower C/N ratio increase the nitrogen efficiency of recycled fertilisers.
Summary translation
Versuche zeigten, dass gelagerter menschlicher Urin, Gärreste und Klärschlamm eine höhere N-Effizienz aufweisen als Kompost. Außerdem erhöhen ein höherer Gehalt an Ammonium-Stickstoff (NH4+-N) und ein niedrigeres C/N-Verhältnis die Stickstoffeffizienz von Recyclingdüngern.

| Teaser: | Improving nitrogen efficiency of organic fertilizers. |
| What problem does the tool address?: | A high share of the nitrogen (N) in recycled and other organic fertilisers is not in a form available to plants and needs to be mineralized before plant uptake. This makes the effect on yields less predictable. |
| What solution does the tool offer?: | Evaluating recycled fertilisers regarding their nitrogen efficiency compared to mineral fertilisers can help estimate the amount of N they supply to the plants and, therefore, their effect on yields. |
