The soil moisture content start and stop points (the irrigation trigger points), for rotationally grazed pasture are often ambiguous and imprecise. 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.
