Why is soil important. Soil plays a vital role in the survival of living beings on the earth. Its importance can be listed as. 1. Soil fertility: Fertile soil supports growth of plants. In-turn these plants produce vital needs to humans like food, clothing, furniture, medicine etc. Even other animals, insects receive food by grazing on plants. 2. Soil microbiology: It provides support for survival of many bacteria, algae, fungi etc..
Soil fertility is greatly influenced by the factors of soil formation. As soils form, nutrients are being continually removed from and added to the soil with time. The conditions that are present during soil formation ultimately determine how much and what kind of nutrients the soil can naturally supply and hold.he type of parent material and how the soil is formed will greatly influence the properties of the soil. There are two general rules that we may state about the influence of parent material on soil formation: 1  Finely textured parent materials tend to weather into finely textured soils.
