    Maximising centre pivot efficiencies : Final report GGP051
    (Sugar Research Australia Limited, 2014) Fox, J
    Centre pivot irrigators are proven to be one of the most efficient irrigation systems. But in the cane industry with long ratoon cycles, and a six month harvest season, a pivot applying the same amount of water over the entire area (and length of pivot) becomes a management issue. With a pivot length of 700 metres, it is common for more than 1 block to be under the pivot at once. It is more than likely that these blocks require different irrigation amounts, while some blocks may not need water at all due to age of crop or blocks about to be harvested, or blocks planted to legume fallows which have different water requirements.
