The results of research project REDUCE (FKZ: 28RZ372030; 28RF372031) clearly prove the significant reduction of ammonia emissions (NH₃ emissions) by 40 to 60 % caused by regular applying urease inhibitor (UI) under practically relevant conditions in naturally ventilated dairy barns. Additional outcome of the project is a usable UI formulation. Based on this the project Prax-REDUCE should accomplish the prerequisites, which are finally necessary to transfer and establish UI usage in broad agricultural practice (cattle farming). Thereby, a feasible, manageable, good controllable and documentable NH₃ mitigation measure should made ready for the market, easily applicable in various types of (dairy) barns. The intended end-to-end solution consisting of UI formulation + doser + mixing and filling unit + application technique is a worldwide new, innovative approach with large reduction capability. This could make an essential contribution to achieve and satisfy German obligations under Directive (EU) 2016/2284 on the reduction of national emissions of certain atmospheric pollutions (ammonia emissions: by 5 % for any year from 2020 to 2029, by 29 % from 2030).
A feasible technique will be development for automatically daily dosage and mixing of the UI formulation with water and subsequently, filing of the application devices and evenly application of UI water mixture on stable floors. Two concepts for application will be pursued robotic manure scraper and flexible hose drop system. Qualified proof of safe usage will be performed based on exposure scenarios and exposure data ascertained under barn conditions. Proving of technique and of whole treatment system will be carried out in practical barns. Subsequently, gained experiences and knowledge will be transferred into practice via application recommendations and user instructions. Exposition data for human (workers), animals (cows) and product (milk) for the risk assessment of urease inhibitor for the application in cattle-sheds are collected.
