ETo – Last Week Totals
Tip: To convert mm to megalitres/ha, divide by 100. Eg. 50mm = 0.5ML /ha.
MID average daily pasture water use over the last week was 5.2 mm/day.
The approximate MID flood irrigation interval based on last week’s daily pasture water use rate was 8 days. (This figure assumes that 30 mm of readily available water is held in the pasture root zone divided by the 5.2 mm/day = 6 days and then add an extra two days to account for waterlogging). This does not take into account any rain your farm may have got during the week which will extend the interval.
Spray irrigators in the MID needed to have applied on average 36 mm of irrigation water for the week to meet pasture water use (5.2 x 7). This irrigation figure does not take into account any rainfall on your farm, which must be subtracted from the required irrigation figure, and assumes that the spray irrigation system is applying water at 100% uniformity. This figure may be greater depending on the specific spray irrigation system uniformity.
