Grain grown per millimetre of growing-season rainfall (less an evaporation allowance) — the truest single measure of how well a season was converted into grain, independent of how wet or dry it was. Barley is inherently more water-efficient than wheat.
The French-Schultz benchmark puts water-limited wheat at about 20 kg grain/ha per mm of growing-season water; modern varieties and agronomy push the achievable ceiling to 22–24 kg/ha/mm.
GRDC Water Use Efficiency ↗A gap between your WUE and the French-Schultz line is the yield you left in the paddock to weeds, poor nutrition, disease or a late sowing — the levers you can actually pull, as opposed to the rain you can’t.
Silo pulls each of these from the sources the operation already uses, and keeps the figure current automatically.
Sow on time into stored moisture to maximise transpiration, not evaporation.
Remove the yield-robbers — weeds, root disease and nutrient shortfalls.
Retain stubble to cut evaporation and hold summer fallow moisture.
