Soil provides medium for plant growth. There are different factors that affect plant growth such as the soil PH, the amount of organic matter and the level of nutrients.  

The microorganisms in the soil make use of the waste present in soil by converting it to manures. Some of the microorganisms found in the soil are solely responsible for the nutrient level. Examples are nematodes, protozoa and many more.

Soil comprises many different material and they develop slowly over a period of time. Soil is present on all the lands not covered by water. There are many types of soil and it is usually based on color, texture, profile and structure.
