Smart blending of enhanced efficiency fertilisers to maximise sugarcane profitability : final technical report RRDP1718

Abstract

Jointly funded by the Department of Agriculture, Water and the Environment, Sugar Research Australia, Queensland Government, and industry and research partners, this project aimed to: (1) characterise PCU N release dynamics in relation to crop N uptake and identify the most desirable PCU formulation for enhanced synchronisation between N supply and crop N uptake; (2) assess the potential benefits of blending PCU with conventional urea as a means to improve N use efficiency and profitability; (3) investigate if use of NI+U or PCU blend could decrease nitrate leaching; and (4) develop a decision support tool to assist with product selection and use.
