At our last Rotary meeting, Glen Johnston gave a very interesting talk about the technology now used on their dairy farm.  The aghub computer system measures soil moisture in real time and also utilises a safety cutoff on the irrigator.  There is real-time mapping of nutrients going onto pasture and they have just purchased a new type of irrigator that allows the spread effluent at a much lower rate.  Technology is now an integral part of their farming business.
