Determine the rainfall factor in soil formation
The movement of water is determined by the nature and amount of rainfall. Where the rainfall is excessive or intense, the constituents carried in solution are completely removed from parent material through percolation, leaching and runoff. On the other hand, if the rainfall is not so intense or is less in amount, the movement of water especially the downward movement, is restricted and the constituents are still retained in soil body. They are leached from upper layers to lower depth where they are re-deposited. When the soil moisture at the surface evaporates causing an upward movement of water, the soluble substances move with it and are translocated to upper layers or even brought to the surface. Rainfall thus brings about a redistribution of substances both soluble and those in suspension in the soil body.
