OG RENURE: Field application of manure-derived ammonium salts as RENURE fertilisers

RENURE aims to prepare the agricultural sector for the use of ammonium salt fertilisers (ammonium nitrate and ammonium sulphate) by making the transition from research-based field trials to a practical evaluation at the farmer's premises. Five field trials were set up in 2022 and one in 2023 to evaluate ammonium nitrate recovered from animal manure through stripping and scrubbing process. Results showed that: • The ammonium nitrate recovered from animal manure performs as well as artificial fertilisers in terms of effectiveness and fertilising value. • Applying ammonium nitrate with a row tiller or with injection is preferred as a low-emission method over application with a spray boom • The status of animal manure in the current regulations is limited for ammonium nitrate application
