We are all working from home but are still contactable by mobile phone and email.
-
- Flood irrigation interval for the last week was 11 days
- Spray irrigation amount was 23 mm of irrigation water for the last week
- The predicted weekly pasture water use for Bairnsdale is 21 mm, MID 21 mm, Orbost 22 mm and Yarram 22 mm
- Glenmaggie is at 48.4%
* These figures are approximate and do not take into account rainfall on farm*

Extension staff are now working from home until it is deemed safe for us to return to work. We are still available for phone calls & are also brainstorming how to support irrigators through this difficult time. If you have any ideas, or things you would like to know about, let us know.
ETo – Last Week Totals
| Location | ETo (mm) | Effective Rain * mm (R) | Dairy pasture coefficient | Required Irrigation mm (ETo – R) |
| Boisdale | 22 | 0 | 1 | 22 |
| Cowwarr | 21 | 0 | 1 | 21 |
| East Sale | 27 | 0 | 1 | 27 |
| Nambrok | 25 | 0 | 1 | 25 |
| Tinamba | 19 | 0 | 1 | 19 |
| Location | ETo (mm) | Effective Rain * mm (R) | Dairy pasture coefficient | Required Irrigation mm (ETo – R) |
| Bairnsdale | 28 | 0 | 1 | 28 |
| Latrobe Valley Airport | 22 | 0 | 1 | 22 |
| Orbost | 20 | 0 | 1 | 20 |
| Yarram | 25 | 0 | 1 | 25 |
* Effective rainfall = daily rainfall minus 2mm.
ETₒ and the “crop coefficient” (conversion factor) of 1.0 applies to a healthy productive pasture 12 cm high.
** This data is not included when doing any of the below calculations
The approximate MID flood irrigation interval based on last week’s daily pasture water use rate was 11 days. (This figure assumes that 30 mm of readily available water is held in the pasture root zone divided by the 3.3 mm/day = 9 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.

| MID | 21 | 0.21 | 3.0 |
| Orbost | 22 | 0.22 | 3.1 |
