Available soil moisture and low soil salinity are difficult to maintain in clay soils of arid regions due to the clay's low permeability. However, a simple procedure has been developed for estimating the duration of flood irrigation needed to saturate the cracked profile in these soils, while improving water conservation through limiting excess runoff. Using a worksheet, the irrigator makes a few measurements, then calculates how long to irrigate each border.
