What is the meaning of Soil Taxonomy?



Soil taxonomy is a morphogenetic soil classification system using diagnostic horizons and features to infer pathways of soil genesis and formation. It employs a unique mnemonic system based on Greek, Latin, or other root words for assigning names to taxonomic classes.

Why is Soil Taxonomy important?

Meaningful comparisons among studies on processes affected by soils require site-specific information; soil taxonomy is a critical piece of site metadata. Proper soils information is fundamental to the site description for ecosystem-scale research and should be expected in journal submissions.

Who developed the Soil Taxonomy?

Dr. Guy Smith

The first edition of Soil Taxonomy, published in 1975, was developed under the leadership of Dr. Guy Smith over a period of about 25 years. The magnitude and complexity of the information favored the use of a hierarchical system presented as a key for consistent application.

What is the highest level of Soil Taxonomy?

soil orders

The highest level is soil orders (similar to kingdoms in the Linnaeus system of classifying organisms). Each order is based on one important diagnostic feature with the key feature based on its significant effect on the land use or management of all soils in that order.

What is soil classification in agriculture?

Soil Classification concerns the grouping of soils with a similar range of properties (chemical, physical and biological) into units that can be geo-referenced and mapped. Soils are a very complex natural resource, much more so than air and water.
