Save everything entered on all tabs, plus the results, to a CSV file on your computer. Load it later to fill the tool back in and recalculate.
24 containers with the same known opening (over 150 mm; 9 litre buckets work well) in a row along the machine: 8 evenly under the first span or two, 8 in the middle of the machine, and 6 under the last span or two. If there is an end gun, put the last 2 between the end wheel track and the edge of significant wetting; otherwise put them under the last span. Avoid the wheel tracks.
Set Out Collectors fills in suggested distances. Replace them with the actual distances if they differ. Record each volume against the correct position.
Put two flags along the line of travel near the wheel track of the machine centre tower, at least 5 m either side of the collector line and easily visible. Time the machine between the flags, including any stops.
What is calculated
- Irrigator speed and time for each run
- Applied depth, overall and under the first, middle and last spans and end gun
- Distribution uniformity and the excess water use factor
- Application intensity, and flow worked out from the collectors
- The speed or timer setting to apply your target depth to 7/8 of the area
