A water balance model, IrriCalc, was used to analyse the impacts of different soil moisture triggers upon the irrigation required and subsequent drainage losses over a long-term period to investigate optimal irrigation ranges within the soil water holding capacity.pp.1-9enirrigationdrainageIrriCalcthreshold soil moisture contentrotationally grazed pastureoptimal irrigation rangeNew ZealandConference Contribution - published
