Irrigation is entered to typical months it is applied. Typical means in an average year, not a drought year or high rainfall season. Most often this is October to April but there are regional variations.
It is also important water supply restrictions are considered when entering in irrigation months e.g., if the water supply is typically not available in February due to river flow restrictions this should be reflected.
The days that you are irrigating in the shoulder months need special attention to ensure the model is appropriately reflecting the management approach. When you select the months irrigation is used the model assumes irrigation occurs for the whole month. If this does not reflect what happens on your farm, it is recommended for the shoulder months you following the steps outlined below:
- Set irrigation schedule to based on Soil moisture sensors (probes or tapes)
- Chose Strategy to Trigger point and fixed depth applied or the most suitable option
- Set Management system definition to default
