Use of real-time in situ nitrogen sensors

Aims & Objectives
To demonstrate how the application of new technologies can enable practical management of nitrogen on livestock farms. The objective is to develop a system using field based sensors to monitor soluble N in real time, to allow active management of fertiliser and organic waste applications.

Expected Outcomes
Validation of the use of real time NO3 sensors on pasture under-going contrasting fertilizer regimes.
Validation of the use of real time NO3 for fertilizer management in fodder crop systems.
