Spreading accuracy of solid urea fertilisers - NT2610

This project investigated the physical nature and spreading characteristics of solid ammonium nitrate fertilisers and compared these to solid urea alternatives. The market availability of urea products was identified and their qualities assessed by a series of laboratory tests. The results of these tests indicated suitable materials that were included in indoor test hall and field experiments. Three typical fertiliser spreaders, two twin spinning disc type and one oscillating spout, were selected and used with a wide range of products and settings to determine the relationship between, particle size, particle density and treatment width. Comparisons were made between indoor hall measurements and field tests. The influence of humidity and wind conditions were studied.
