How to use this tool

  1. Enter watered area, period crop water use, observed rainfall, effective rainfall fraction, and irrigation delivery efficiency in the displayed units.
  2. Calculate and use each labeled result for garden water deficit balance. Compare the result with a measured sample before committing materials.

Try this example

{
  "area": 40,
  "use": 25,
  "rain": 12,
  "effective": 80,
  "efficiency": 90
}

Accuracy and scope

Water-budget scenario only; crop use, rainfall effectiveness and irrigation efficiency are inputs, not local recommendations. Soil storage is excluded.
