Field experiments carried out successfully

The first season of field trials within ReNu2Farm was successfully completed in the autumn of 2019. Field trials were carried out in the Netherlands, Ireland, France and Belgium to investigate the fertilizer value and environmental effects of recycling-derived fertilizers. Teagasc (Ireland, grassland) and Arvalis (France, spring barley) conducted field trials researching the phosphorus fertiliser value of ash and struvite. Inagro (Belgium, maize) researched the nitrogen value at short-term of recovered liquid nitrogen products (e.g. digestate, ammonium nitrate and ammonium sulphate). The trial in Belgium is also part of the European Commission's SAFEMANURE campaign. NMI (Netherlands) carried out a field trial with maize at two different locations on sandy soil. The effect of household waste compost, roadside grass cuttings and cattle manure on yield, organic matter content of the soil and nitrate leaching was compared.

The project partners intend to repeat the trials in 2020 to increase the reliability of the results.
