Irrigation Volume Guide (Quick: Crop, Soil, Heat)
Shows a per-event watering range based on crop category, soil type, heat, mulch, and irrigation method.
Needs vary widely by region, wind, solar radiation, and growth stage. Use as a guide and adjust by checking soil moisture (5–10 cm depth).
Quick irrigation calculator: watering volume estimate per event (range).
Even for the same crop, requirements vary by region, wind, solar radiation, growth stage, bed shape, and drainage.
Adjust by checking soil moisture (5–10 cm depth).
Calculate irrigation range (How many liters per watering?)
Minimal inputs. We show a range so you can adjust in the field.
- Wilting even in the morning → increase
- Always wet and smells → decrease / improve drainage
- Wilts only midday and recovers by evening → no sudden increase (watch)
How soil (sand/loam/clay) changes watering
Sandy soils dry quickly so increase frequency. Clay holds water and can get waterlogged, so fewer events are often better.
Watering guide on hot days (high temperature)
High temperature, strong sun, and dry wind increase evapotranspiration. Even if you aim at the upper range, always verify soil moisture.
Hoe te gebruiken (3 stappen)
- Select conditions
- Check the range
- Fine-tune by soil moisture and crop condition
Simple logic (transparency)
This prioritizes practical ranges over strict ET calculations.
- Leafy greens: 0.3–0.8 L/plant
- Fruit vegetables: 1.0–2.5 L/plant
- Root vegetables: 0.6–1.8 L/plant
- Beans: 0.6–1.6 L/plant
- Fruit trees (young): 10–25 L/tree
- Fruit trees (mature): 30–80 L/tree
- Soil: sand ×1.10 / loam ×1.00 / clay ×0.90
- Mulch: yes ×0.85 / no ×1.00
- Heat: low ×0.80 / medium ×1.00 / high ×1.25
- Method: drip ×0.90 / sprinkler ×1.00
- Up to ~5 L: 0.1 L steps
- 5–30 L: 0.5 L steps
- 30+ L: 1 L steps
FAQ (ET calculation, units, dry fields)
How do I do accurate ET calculation?
This tool is a quick guideline. For higher accuracy, estimate ET from weather data (temperature, solar radiation, wind, humidity) and multiply by crop coefficients. If needed, we can provide a weather-linked ET version separately.
What units are supported?
Base is L/plant. Enter area and plant count to switch to L/m² or mm. Note: 1 mm = 1 L/m².
My field dries out easily.
We adjust by soil type (sand/loam/clay). If it still dries quickly, a smaller amount with higher frequency can be more stable (especially for sandy soils).
注意事項（免責）
- Results are estimates. Required water varies widely by region, weather, wind, solar radiation, growth stage, drainage, mulch type, bed shape, and fertilization.
- Always check soil moisture (5–10 cm depth) and crop condition, and adjust if you see waterlogging or drought signs.
