Rice usually requires 800 mm to 1,200 mm of water with extremes between 520 mm and 2,550 mm during the growing season. Daily crop water requirements are usually between 6 to 10 mm, however excessive percolation losses in sandy soils can greatly increase water consumption and also increase fertilizer requirements.

How much water does a rice plant need?
Traditional farming needs 3,000 to 5,000 liters of water to produce a kilo of rice. The crop requires flooded soil for its growth as it suppresses weed growth and increases the uptake of nutrients from the soil for better yield.
