Kalkulačka zavlažování zahrady odhaduje, kolik vody rostliny potřebují na základě velikosti květináče, typu rostliny a počasí. Přemokření je pro většinu rostlin stejně škodlivé jako podmáčení.

Calkulon makes complex calculations simple — built for students and everyday problem-solvers.

Vzorec

▾

f(x)Potřeba vody (L) = plocha (m²) × hloubka (cm) × 10 | Většina rostlin: 25–50 mm/týden nebo 1–2 palce

How to Plant Watering Calculator

▾

1Pot volume (L) × 10–20% = volume per watering
2Outdoor beds: ~20–25mm per week in dry weather
3Rain gauge: 1mm rainfall = 1 L/m² of garden
4Finger test: soil dry 2–5cm deep → time to water (most plants)

Worked Examples

▾

Example 1

Given:10L pot, watering when top 3cm dry

Výsledek:Add ~1–2L per watering; frequency increases in heat
