What are soil mapping methods?

Soil mapping involves locating and identifying the different soils that occur, collecting information about their location, nature, properties and potential use, and recording this information on maps and in supporting documents to show the spatial distribution of every soil.

What are soil mapping units?

A soil map unit is a collection of areas that are relatively homogeneous in soil constitution or miscellaneous areas that constitute different soil components or both. From: Reference Module in Earth Systems and Environmental Sciences, 2021.

What are the importance of soil classification in today’s environment?

The purpose of soil classification is to help farmers, gardeners, engineers, stormwater management experts, community planners, and many other professionals and hobbyists plan what to grow, what to build, and where to build. Soil classifications tell you a soil’s texture and the ability of water to penetrate it.

Which components are typically used in a soil map unit name?

Soil surveys use four kinds of map units to distinguish the different relationships: consociations, complexes, associations, and undifferentiated groups. In a consociation, delineated areas use a single name from the dominant component in the map unit.

How are map units identified?

A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils.

What is TIFF soil?

The Tiff series consists of very deep, well drained, moderately permeable soils that formed clayey residuum on uplands. These soils are on nearly level to moderately steep areas that have been truncated by mining operations. Slopes range from 1 to 20 percent.
