Influence Of Water Supply On Farm Productivity In The North-Eastern Wheatbelt, E J. Hauck

Resource management technical reports

In the area with reliable reticulated water supplies, average what yield, average wool production and average number of sheep per pastured hectare showed a positive correlation with annual rainfall in all but one year. By contrast, in the area served by on-farm water supplies only, average wheat yield and annual rainfall were strongly correlated, whereas average wool production and average number of sheep per pastured hectare showed a weaker correlation with annual rainfall. These correlations suggest tt on farms with a reliable water supply, livestock numbers have been adjusted annually to ensure optimum utilisation of available feed in all seasons.
