Smart Irrigation Calculator
Estimate daily & weekly water needs and get an optimized watering schedule to save water and improve yields.
Calculate Water Requirement
Fill required fields. The calculator uses reference evapotranspiration (ET0) approximations and crop coefficients (Kc) to estimate crop evapotranspiration (ETc).
About ET and irrigation planning
Reference evapotranspiration (ET0) reflects atmospheric demand and is influenced by sunshine, temperature, humidity and wind. Crop coefficient (Kc) adjusts ET0 for crop type and growth stage.
