1.Soil fertility: Fertile soil supports the growth of plants. In-turn these plants produce vital needs for humans like food, clothing, furniture, medicine, etc. Even other animals, insects receive food by grazing on plants.
Soil microbiology: It provides support for the survival of many bacteria, algae, fungi, etc.. These bacteria and microbes present in soil help in environmental balance like retaining of moisture, the decay of dead bodies of animals, plants, etc., scavenging of waste and other toxic chemicals including plastic.
3. Topsoil provides shelter for insects, reptiles, birds, and animals. Further topsoil is necessary for even other activities like nesting, reproduction, hatching of eggs, breeding, etc.
4. Soil organic matter contains essential minerals and elements like phosphates, sulfates, calcium, zinc, magnesium and many more. These elements are provided to plant during growth and from there to all the living forms. Hence they act as a source of essential minerals and elements needed for various enzyme and cell reactions.
5. Soil a source of minerals: Minerals and mines present in the soil is the source of many metals like iron, bauxite, zinc, etc. Many metal elements are mixed up with soil and hence extracted from soil by technical processes.
6. The soil is used for making utensils, tiles, etc. The utensils like cups, plates china clay, plaster of Paris, etc. Tiles used in home or building made of ceramic-like soil components.
7. Soil contents like gravel, clay, sand, etc. are widely used for the construction of homes, buildings, roads, etc
8. Soil a source of medicines: Soil gives us some important mineral medicines like calcium (bones), iron (hemoglobin) bentonite (laxative) and other substance like petroleum jelly, steatite for cosmetics, talcum powders, etc.
9. Soil keeps atmosphere cool: Soil absorbs water when there is rain and so when is there is heavy sun heat, this water from soil evaporates making the air cooler.
10. Home for animals, birds & insects: Soil is the natural dwelling place for many living beings. Animals like, rats, mice, guinea pigs, mongoose, squirrel, etc. live in the burrows made in the soil. Reptiles like snakes, lizards live in the soils. Even insects live and nest in the soil. Some birds also nest in the soil.
