FACTSHEET: Nitrogen cycling and accounting for increased nitrogen use efficiency

MAY 2025 This factsheet aims to help growers improve nitrogen use efficiency (NUE) by understanding how nitrogen cycles through the soil-plant system. It outlines practical strategies to reduce nitrogen losses, highlights the role of cover crops and organic matter, and provides step-by-step guidance on calculating nutrient requirements and crop removal. With rising fertiliser costs and environmental pressures, this resource supports growers in making informed, sustainable nutrient management decisions.
