Rain Gauge Irrigation Credit Calculator
Credit measured effective rainfall against a weekly water target. The form keeps the source measurements beside the calculated remaining irrigation need.
Enter values for remaining irrigation need
Keep Rain Gauge Irrigation Credit units with their measurements.
Rain Gauge Irrigation Credit field limitation
Reset the rain gauge and irrigation week on the same schedule.
Weekly water target and the other inputs
Prepare Weekly water target and Measured effective rain for Rain Gauge Irrigation Credit. Keep unrelated records separate.
- Weekly water target
- The Rain Gauge Irrigation Credit target is 1.2 in in the starting case.
- Measured effective rain
- Rain Gauge Irrigation Credit currently demonstrates 0.45 in; substitute the observation being evaluated.
Collecting data for Rain Gauge Irrigation Credit
Measure delivery at normal operating pressure and note the zone being tested. Nominal flow is not a substitute for a catch-can or timed-volume check.
Worked remaining irrigation need example
Rain Gauge Irrigation Credit finds the difference using Weekly water target and Measured effective rain.
For the prefilled measurements—weekly water target at 1.2 in and measured effective rain at 0.45 in—the calculated answer is 0.75 in.
Using the Rain Gauge Irrigation Credit result
Remaining irrigation need belongs to the Rain Gauge Irrigation Credit scenario. Recalculate remaining irrigation need for another case.
Remaining need relative to rainfall supplements remaining irrigation need in Rain Gauge Irrigation Credit.
After calculating remaining irrigation need
For Rain Gauge Irrigation Credit, preserve Weekly water target and Measured effective rain and the resulting Remaining irrigation need. Continue with Evapotranspiration Irrigation Need Calculator to subtract effective rainfall from crop water use.
Mark weekly water target as observed or assumed and cite the product label, test, count, or measurement when applicable.
After use, record what happened in the garden on the same basis as remaining irrigation need.
A second Rain Gauge Irrigation Credit scenario
A ten-percent test change in Weekly water target replaces 1.2 in with 1.32 in. Under the remaining sample values, remaining irrigation need changes from 0.75 in to 0.87 in.
Only weekly water target changes in this Rain Gauge Irrigation Credit example, making its numerical effect visible.
Keep the original remaining irrigation need and the test result as separate scenarios.
Questions about Rain Gauge Irrigation Credit
How does “Reset the rain gauge and irrigation week on the same schedule.” affect remaining irrigation need?
The displayed result will not detect that condition. Check weekly water target against the actual site before using it.
How should rainfall be handled in Rain Gauge Irrigation Credit?
Use only the effective rainfall quantity named by Rain Gauge Irrigation Credit. Keep gross rainfall and irrigation delivery as separate records.
