Nitrogen management key driver of WUE

The rate of nitrogen (N) fertiliser applied is the stand-out variable influencing water use efficiency (WUE) in wheat crops. This was the main finding in a four-year research trial in western Victoria. Ten variables accounted for a third of the WUE variation between sites.

Looking for better yields from sandy soils

Sandy soils can show poor water use by crops. There are around 5 million hectares of sandy soils in Australia’s low-medium rainfall southern region. Growers see poor crop performance even with residual subsoil water at harvest.
To date, options to improve sandy soils are either:

Mitigation: lower-cost, annual activities.  Techniques include […]
