The amount of water a soil can absorb depends on: the amount of water already in the soil and the texture of the soil. In addition organic matter can increase soil water holding capacity. Clay soils can hold the greatest amount of water but they hold some of it too tightly for plants. In a clay, 30 cm depth of soil could absorb 10 cm of precipitation. Sand holds much less with 30 cm of sand holding only 3 cm of precipitation
