soil morphology

The classification is based mainly on soil morphology as an expression pedogenesis.

The ability to assess cutans is a core skill in soil morphology and paleopedology.

In the 1960s, a different classification system began to emerge which focused on soil morphology instead of parental materials and soil-forming factors.

C1.1 Soil morphology and micromorphology.

Soil classification can be approached from both the perspective of pedogenesis and from soil morphology.

Pedology - study of soils in their natural environment that deals with pedogenesis, soil morphology, and soil classification.

Pedology mainly deals with pedogenesis, soil morphology, soil classification.

Burrowing animals and insects, and plant root systems create passageways for air and water movement, changing soil morphology.

Pedology deals with pedogenesis, soil morphology, and soil classification, while edaphology studies the way soils influence plants, fungi, and other living things.

In soil survey, as practiced in the United States, soil classification usually means criteria based on soil morphology in addition to characteristics developed during soil formation.

Soil morphology provides a firm basis on which to group the results of observation, experiments, and practical experience and to develop integrated principles that predict the behavior of the soils.

Soil morphology is the field observable attributes of the soil within the various soil horizons and the description of the kind and arrangement of the horizons.

C.F. Marbut championed reliance on soil morphology instead of on theories of pedogenesis for soil classification because theories of soil genesis are both ephemeral and dynamic.

For soil resources, experience has shown that a natural system approach to classification, i.e. grouping soils by their intrinsic property (soil morphology), behaviour, or genesis, results in classes that can be interpreted for many diverse uses.

Pedogenesis is though more a parent than a branch of pedology, whose other aspects include the soil morphology, classification (taxonomy) of soils, and their distribution in nature, present and past (soil geography and paleopedology).

Systems have developed, such as USDA soil taxonomy and the World Reference Base for Soil Resources, which use taxonomic criteria involving soil morphology and laboratory tests to inform and refine hierarchical classes.
