Measured Irrigation – from Dr. Bernie Omodei
Over the last few years we have been fascinated to see the many innovative, low-tech irrigation, low-cost controllers and systems that South Australian Engineer Dr. Bernie Omodei has invented and made available. All of Dr. Omodei’s irrigation control units use low-tech and widely available materials and devices. He also provides DIY instructions for some of his units. Perhaps the strongest theme of his devices are that they work with (typically low pressure) gravity fed water supplies and the water usage rates they control is directly proportional to the net evaporation rate (i.e. evaporation minus rainfall)—and the changes in canopy cover (shade) or positioning of the measured irrigation control units will dynamically adjust the irrigation provided (e.g. inside greenhouses/polytunnels). Dr. Omodei’s valve’s work in concert with rainwater tanks or other gravity water storages—another reason why we recommend their consideration for both small holders and for commercial market gardeners.
