Soil organisms play a vital role in maintaining the soil. They carry out the important process of decomposition which adds valuable organic matter to the soil. This not only helps help the soil in maintaining its nutritional balance but also its texture and water holding capacity. The movement of organisms also helps to create air spaces which helps the roots to breathe. Thus the organisms help in tilling the soil in the soil preparation stage.
