An assessment of controlled release fertilisers in the Australian sugar industry [Full subscriber]

Abstract Nutrient loss is a significant issue faced by the sugarcane industry in tropical Australia. Controlled release (CR) fertilisers may offer significant opportunities to reduce nutrient losses leading to potential improvements in nutrient efficiencies, productivity gains and improved environmental outcomes. This paper reviews the research undertaken in the Herbert, Burdekin and Mackay cane growing regions of Australia, comparing the Everris® Agrocote® controlled release urea against conventional urea products. Controlled release N significantly increased cane and sugar yield compared to similar rates of urea N in the Burdekin and Herbert. Significant yield responses were measured in seasons with both wet and…
