Strawberry Water Requirement Calculator
Work out the seasonal and per-irrigation water requirement of strawberry (FAO-56 ETc = ET₀ × Kc, peak Kc 0.85) for your field, climate, soil and irrigation method.
Drip under plastic mulch is standard — it keeps the shallow roots evenly moist and the crown/fruit dry against rot. Never let strawberry wilt during fruiting; never wet the foliage.
Indicative planning figures based on published research averages. Local soil tests, varieties and weather change actual requirements — confirm with your agronomist or extension officer.

About Strawberry Water Requirement Calculator
Shallow-rooted strawberry needs 400–600 mm of very steady drip moisture; it is intolerant of both drought and wet crowns. This calculator uses the FAO-56 method — crop evapotranspiration ETc = ET₀ × Kc — with strawberry's own crop coefficients (Kc 0.4 initial, 0.85 mid-season, 0.7 late) across a 120-day season. Pick your climate band (which sets reference ET₀), irrigation method (drip, sprinkler, pivot or surface — each with its own efficiency) and soil texture, and it returns the seasonal water need in cubic metres, the peak daily demand, the net depth per irrigation and how many days to wait between irrigations.
How to use Strawberry Water Requirement Calculator
- 1Enter your field area and choose the climate band matching your season.
- 2Select your irrigation method and soil texture.
- 3Read the seasonal water volume, peak daily demand and irrigation interval, then follow the scheduling note.
Why use Strawberry Water Requirement Calculator?
- ✓Uses strawberry's real FAO-56 Kc curve, not a flat factor
- ✓Accounts for drip / sprinkler / pivot / surface efficiency
- ✓Gives seasonal volume, peak daily need and an irrigation interval
- ✓Free, instant and fully in-browser — works offline in the field
Frequently asked questions
How much water does strawberry need?+
Shallow-rooted strawberry needs 400–600 mm of very steady drip moisture; it is intolerant of both drought and wet crowns. The exact figure depends on climate and season length; this tool sums ET₀ × Kc across the crop's 120-day growth stages for your conditions.
Why is drip irrigation essential for strawberry?+
Its shallow roots can't buffer dry spells, and overhead water rots crowns and fruit. Drip under plastic mulch keeps moisture steady at the roots while keeping the canopy dry.
How much water does strawberry need?+
About 400–600 mm over the season, with steady demand through fruiting. Frequent small drip doses suit the shallow root system best.
What is ET₀ and Kc?+
ET₀ (reference evapotranspiration) is how fast a standard grass surface loses water in your climate. Kc (crop coefficient) scales it to a specific crop and growth stage. Crop water use ETc = ET₀ × Kc — the basis of FAO-56 irrigation scheduling.
Is this calculator free and private?+
Yes — free, no sign-up, and all calculation runs in your browser, so it works offline in the field and your data never leaves the device.
