A pump efficiency trial at Goondiwindi has highlighted the importance of testing individual pumping set-ups to identify the optimum operating point to achieve maximum efficiency. This case study features grower Hamish Johnstone of 'Macintyre Downs', Goondiwindi. 

An energy efficiency audit of the new overhead irrigation system on Adam McVeigh’s Darling Downs farm in southern Queensland has set him on the path to reducing emissions and making big savings in energy costs.

GUNNEDAH farmer Scott Morgan has slashed the amount of money he spends on electricity used to irrigate cotton on his property, “Kensal Green”, by investing in solar and by reducing the amount of energy he uses to pump water for his crops.

An energy expenditure that had been climbing by around 10 per cent per year coupled with concerns about climate change have prompted St George cotton irrigators Ian and Anne Brimblecombe, “Burgorah”, to install solar panels which generate 100kW of electricity.

Reducing pumping costs by $10 an hour with a diesel-gas mix has put money in the pocket and a smile on the face of irrigated cotton grower Warwick Wannan of 'Kurrawombi Downs', Baan Baa.
