Title Optimal use of recycled fertiliser in organic farming: impact on yields and nitrogen efficiency
Title Original Optimaler Einsatz von Recyclingdüngern im Biolandbau: Ertragswirkung und Stickstoffeffizienz
Official Acronym Recycle4Bio
FiBL project number 10107
Abstract

The production and use of recycled fertiliser from biogas plants are increasing. However, a lot of questions remain unanswered concerning the fertilisers’ medium-term effects on yields, nitrogen efficiency and losses as well as on soil quality.

In this project, an exact trial over several years testing various recycled fertilisers with and without biochar is created to answer the following questions:

  • Can the use of recycled fertilizer help reduce the yield gap in organic farming without affecting soil quality, product quality and the environment?
  • Can the nitrogen efficiency on organic farms be sustainably improved by using recycled fertilisers, especially fermentation products?
  • Can nitrogen losses be reduced by adding biochar without risking any negative effects on soil quality and the environment?
