FAQ
How is irrigation volume calculated?
Water (L) = area (㎡) × depth (mm). 1mm is 1L per ㎡, so 100 pyeong (330.6㎡) at 10mm needs about 3,306L (3.3 tons).
How long does it take?
Time = water ÷ flow rate (L/h). Enter your drip or sprinkler flow for the time.
What depth (mm)?
It depends on crop, stage and weather; 5-20mm per event is common. Adjust to soil and climate.
