What is a Pedologist?

A pedologist is someone who, by virtue of specialized higher education, training and experience with soils - that group of natural bodies occupying the unconsolidated portion of the earth's surface and having physical and chemical properties due to the combined effect of climate and living organisms, as modified by topography and time, upon parent material --is able to:

1. Identify soils as natural units on the landscape,
2. Differentiate soil types and landscape units, then document their location on aerial photographs or other suitable base map,
3. Describe their characteristics and properties, and recognize their limitations for various land uses, and
4. Promote their wise utilization. 

Pedology is one of the main branches of soil science, dealing with the formation, description, and classification of soils. Therefore, all pedologists are soil scientists.
