Soil is a naturally occurring substance forming the thin uppermost layer of the earth’s surface made by the accumulation of the weathered materials on which plants and animals live.
The following are the importance of soil:
- Soil is the medium in which most of the plant grow and thus soil is used to grow crops;
- Soil forms the foundation of engineering structures and sewage disposal;
- Soil enables the filtration of surface water. When surface water percolates through the soil, dust, chemicals, and other contaminants are filtered out making aquifer (underground water) one of the purest sources of water;
- Certain soil contains minerals that can be extracted commercially for example apatite minerals are extracted from the lateric soils and used as important raw materials for manufacturing phosphate fertilizers;
- In many parts of the world when people die they are buried in the soil.
