NESP2.1.8 (Cane) Improved Water Quality Outcomes from On-Farm Nitrogen Management
A comprehensive review of N use in sugarcane identified widespread over-use of N fertiliser and recommended adopting production unit yield potential (PUYP) combined with enhanced efficiency fertilisers (EEFs) to reduce ’surplus N’ (where applied N >is greater than crop requirements). This project will utilise existing farm trials at identified N loss ‘hot spots’ to test PUYP as the basis for determining fertiliser N rates and compare EEFs with standard N fertilisers for minimising N losses, and to examine the water quality benefits that derive from such practice changes. Productivity, economic and environmental indicators will validate these strategies for reducing surplus N and provide recommendations for enhanced BMP’s.
