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. [1]
Paedology (also spelled pedology or paidology) is the study of children's behavior and development. It may be considered distinct from pedagogy , the art or science of teaching, and pediatrics , the field of medicine relating to children.
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.
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 ...
Soil formation, also known as pedogenesis, is the process of soil genesis as regulated by the effects of place, environment, and history. Biogeochemical processes act to both create and destroy order ( anisotropy ) within soils.
The meaning of the term "pedagogy" is often contested and a great variety of definitions has been suggested. [6] The most common approach is to define it as the study or science of teaching methods. [6] [7] In this sense, it is the methodology of education.
Paleopedology (palaeopedology in the United Kingdom) is the discipline that studies soils of past geological eras, from quite recent to the earliest periods of the Earth's history. Paleopedology can be seen either as a branch of soil science ( pedology ) or of paleontology , since the methods it uses are in many ways a well-defined combination ...
Since the origin of agriculture, humans have understood that soils contain different properties which affect their ability to grow crops. [4] However, soil science did not become its own scientific discipline until the 19th century, and even then early soil scientists were broadly grouped as either "agro-chemists" or "agro-geologists" due to the enduring strong ties of soil to agriculture.
