The soil classification system is important in determining the number of building and landscaping limitations on any particular piece of land. All soils react to changes in moisture, therefore the soil on which you build your foundations must offer sufficient support.

Why do we need to identify the classification of soil?

The main purpose of the systems for soil classification is to group different types of soil into classes having similar characteristics to thereby provide a systematic method to describe the soil.

This system also provides a common language for scientists.

What was the purpose of the soil classification system?
