Watering and Irrigation
Tree Canopy Watering Calculator
Tree Canopy Watering requires one defined scenario. Estimate tree irrigation volume from canopy area and a depth-equivalent rate. Use canopy area and water depth from the Tree Canopy Watering record.
Enter values for water per event
Keep Tree Canopy Watering units with their measurements.
Measurements for Tree Canopy Watering
Prepare Canopy area and Water depth for Tree Canopy Watering. Keep unrelated records separate.
Canopy area. Default in Tree Canopy Watering: 180 sq ft.
Water depth. Default in Tree Canopy Watering: 0.12 gal/sq ft.
Applying the water per event result
Save the weather date with water per event. Temperature, wind, humidity, and plant size can change the next schedule.
Sensitivity of the Tree Canopy Watering result
Run another case with Water depth changed and the other inputs held constant. The difference in water per event then shows the effect of that assumption within this formula.
Tree Canopy Watering beyond the formula
New trees may need water focused over a smaller root-ball area.
Tree Canopy Watering in practical terms
Tree Canopy Watering focuses on Water per event and combines Canopy area and Water depth.
Use water per event to estimate tree irrigation volume from canopy area and a depth-equivalent rate, then inspect canopy area in the field.
Arithmetic used for Tree Canopy Watering
Tree Canopy Watering multiplies factors from Canopy area and Water depth to produce water per event.
Canopy area at 180 sq ft, water depth at 0.12 gal/sq ft produces 21.60 gal in the demonstration case.
Test Tree Canopy Watering with Canopy area at 198 sq ft rather than 180 sq ft. The displayed water per event becomes 23.76 gal instead of 21.60 gal.
The test holds water depth constant.
Test a measured range for canopy area when it may alter the decision.
Using the Tree Canopy Watering result
Read Water per event as the answer to “Estimate tree irrigation volume from canopy area and a depth-equivalent rate.” Keep the Tree Canopy Watering units attached.
Documenting water per event
Write down Canopy area and Water depth before acting on Water per event. After this result, Irrigation Frequency Calculator can estimate irrigation interval from stored water and daily use.
The Tree Canopy Watering note should distinguish direct observations from rates, forecasts, targets, and other assumptions.
Once an actual outcome is available, enter it separately using the same definition as water per event.
Water per event questions
How does “New trees may need water focused over a smaller root-ball area.” affect water per event?
Tree Canopy Watering uses the entered numbers only. Let canopy area reflect that condition before calculating.
Does Tree Canopy Watering adjust itself as crop demand changes?
No. Recalculate water per event after meaningful changes in weather, canopy size, root depth, or irrigated area.
