The behaviour of some different fertiliser-N materials - Initial field experiments - NT2603

This project will compare alternative N fertiliser materials (calcium ammonium nitrate, urea, urea+urease inhibitor Agrotain, urea ammonium nitrate solution, urea ammonium sulphate and ammonium sulphate) with ammonium nitrate in a wide range of cropping, soil type and climatic situations within the UK. UK manufactured ammonium nitrate will be included in the comparison. The monitoring programme will include measurement of nitrogen release patterns, nitrogen loss pathways (ammonia and nitrous oxide emissions, spring leaching) and agronomic performance (crop yield and quality). The research output will be used to assess the performance of these alternative N fertiliser materials, to validate ammonia emission factors and to provide practical information for farmers.
