These features occur in patterns of soil type distribution, forming in response to differences in soil forming factors. [1] Pedogenesis is studied as a branch of pedology, the study of soil in its natural environment. Other branches of pedology are the study of soil morphology and soil classification.
A soil scientist examining horizons within a soil profile. Soil science is the study of soil as a natural resource on the surface of the Earth including soil formation, classification and mapping; physical, chemical, biological, and fertility properties of soils; and these properties in relation to the use and management of soils.
A soil scientist is a contributor to soil science. Soil scientists include agrologists , pedologists and soil classifiers . The following is a list of notable soil scientists .
Soil Profile on Chalk at Seven Sisters Country Park, England. Pedology (from Greek: πέδον, pedon, "soil"; and λόγος, logos, "study") is a discipline within soil science which focuses on understanding and characterizing soil formation, evolution, and the theoretical frameworks for modeling soil bodies, often in the context of the natural environment.

The history of edaphology is not simple, as the two main alternative terms for soil science—pedology and edaphology—were initially poorly distinguished. [10] Friedrich Albert Fallou originally conceived pedology in the 19th century as a fundamental science separate from the applied science of agrology, [11] a predecessor term for edaphology, [12] a distinction retained in the current ...
In his two books First Principles of Soil Science (1857, 2nd ed. 1865) and Pedology or General and Special Soil Science (1862) Friedrich Albert Fallou developed his collected field observations of soil into a systematic approach. He explained why soil formation was worthy of study and appealed for recognition of soil science as a discipline. In ...
Soil piping is a particular form of soil erosion that occurs below the soil surface. [237] It causes levee and dam failure, as well as sink hole formation. Turbulent flow removes soil starting at the mouth of the seep flow and the subsoil erosion advances up-gradient. [ 238 ]
A soil profile is one face of a pedon, or an imaginary three-dimensional unit of soil that would display the full range of properties characteristic of a particular soil. Pedons generally occupy between 1 and 10 m 2 of surface land area and are the fundamental unit of field-based soil study. [9]
