Contributor South Australian No-till Farmers Association
Trial location(s) Wollongbar, NSW

Ultra high pressure injection of nitrogen (UAN) locations
Aims

To assess the potential to use Ultra High Pressure (UHP) liquid injection technology to apply an ultra low soil disturbance UAN sideband into cropping soils and test whether UHP injection of UAN is a viable alternative N application method for the future. 

Key messages

Field observation suggests the 50% UAN solution produced a better stubble cutting action than water alone.
