Nitrogen is one of a number of essential elements for plant growth. Soil nitrogen supply limits crop yield in many situations. Managing nitrogen inputs to optimise crop yield, quality and nitrogen use efficiency (NUE) while minimising nitrogen loss is often an important part of crop & pasture management.
The best management guides below provide a summary of management practices for a range of industries to help manage nitrous oxide emissions and improved NUE:

Nitrous oxide is a naturally occurring, powerful greenhouse gas emitted from agricultural soils. The industry sector nitrous oxide science reviews below will being you up to date with the most recent Australian science outlining the key processes and evaluation of management practices that relate to BMPs.

Safeguage
Safeguage can help you develop nutrient management strategies to reduce the risk of off-site nutrient movement. It is a model with simple inputs which provides a relative risk indicator of different nutrient loss pathways. Safeguage is available for sugarcane, dairy pasture and high rainfall zone grain growing.
