Decomposed vegetal and animal remains, referred to as humus, add to the fertility of such as phosphorus and potassium, necessary for plants .It contains organic matter that is the structure of soil. Soil fertility can be improved by fertilizer to the soil to make up for the nutrients.all soils are formed in situ, that is, they formed in their original position by the break up of parent rocks. They include black the soil and humus silica clay soil, laterite soil, desert soil, etc.
