5.7.3 Irrigation Requirement 2006/07 (Ir(06/07))<br />
The Irrigation Requirement (Ir) for the current period is<br />
calculated in the same way as the BIr, except current ETo<br />
and rainfall data is used. Current data can be accessed from<br />
the BoM on the following website:<br />
www.bom.gov.au/anon2/home/sa/DATA/evapotrans/<br />
Appendix No 1 – IPOS - Irrigation Requirement Model provides<br />
a model for the calculation <strong>of</strong> the Irrigation Requirement (Ir)<br />
Table No 5 details Ir (06/07) for each <strong>of</strong> the turf classifications.<br />
In regional areas, site specific climatic data can be sourced<br />
from the Bureau <strong>of</strong> Meteorology website or private weather<br />
stations in regional areas and other factors remain the same.<br />
The methodology and factors used for calculating the<br />
Irrigation Requirement for landscapes other than turf can be<br />
found in the Certified Landscape Irrigation Auditor Resource<br />
Manual 2004 available from the Irrigation Australia Limited.<br />
