The research conducted in this project underpins rice crop nitrogen management in south east Australia. Insufficient or excess nitrogen can reduce rice grain yields and profitability. The NIR Tissue Test service is a critical tool used by rice growers to determine mid-season nitrogen topdressing rates. Rice growers benefit from this research through improved nitrogen management of their rice crops which leads to increased grain yield, water use efficiency and profitability which all result in a competitive rice industry in Australia.

Investigations into predicting the nitrogen status of rice crops from remotely sensed data are encouraging. If this can be achieved with a suitable level of accuracy, reliance on physical sampling of rice crops to provide accurate nitrogen topdressing recommendations is reduced.
