The previous paper dealt with the broad fundamentals underlying the moisture requirement of pastures. In making my contribution to this symposium I will attempt to consider the implications of these principles in determining a practical irrigation schedule and to discuss the management of irrigated pastures. Firstly the irrigation schedule: Mr Rickard has indicated that the rate of water use by pastures is between 0.1 and 0.2 per day and that growth begins to be affected when the amount lost from the soil is of the order of 1 to I in., that is, when a deficit of 1 to 14 in. is built up.
