Effect of different N timings through the growing season on Canola and the subsequent impact on flowering, yield and oil content.

A long-term trial to assess how wheat responds to N and P fertilizer applications after gypsum and lime application with and without incorporation

The aim was to compare and contrast the effects of liquid fertilisers (UAN & MAXamFLO) on growth and yield over a three year rotation of Barley (2014) Barley (2015) and Canola (2016).

The aim was to investigate responses to phosphorus, nitrogen and potassium in wheat at Muntadgin

The aim is to test and calibrate the extension of nitrogen-rich strips (N Gauges), Normalised Difference Vegetation Index (NDVI) measurement and the In-Season Nitrogen Calculator N-CALC) to assist in mid-season nitrogen decisions and maximise nitrogen efficiency and returns.
