Saturated soil culture
In saturated soil culture (SSC), the soil is kept as near to
saturation as possible and it requires regular shallow irrigation (standing
water depth 1 cm) on daily basis or once in every two days.The best way of
using SSC is in raised
beds in which the soil can be kept around saturation effectively. The raised
beds are used for growing rice and shallow irrigation is applied in furrows.About 5-50% water can be saved if SSC is used scientifically. However,the
saving of water varies with soil type and groundwater table depth.On average, SSC can decrease water input by 23% from the continuously
flooded condition with non-significant yield reduction upto 5-10%.This
technology is a good alternative to flooded rice production in semi-arid
tropical environment.
