The Texas Land Survey System is often measured in Spanish Customary Units. The most important of these is the vara, which, while ambiguous in the past, was legally established to be exactly 33 + 1 ⁄ 3 inches (846.67 mm) long in June 1919. [2] The subdivision levels in Texas are as follows: [3]
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]
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 ...
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 property abstract is a summary of the legal documents that chronicle transactions associated with a particular parcel of land. Generally included are references to deeds , mortgages , wills , probate records, court litigations , and tax sales —basically, any legal document that affects the property.
Pedodiversity is introduced to pedology to analyze soil spatial patterns, soil geography, and test the pedogenetic theories. Thus, pedodiversity is not only concerned with analysis of the pedotaxa number in a given area or region, but it should tackle also with the pedological structures, spatial pedotaxa and soilscapes structure.
Two historical events during the nineteenth century had a great effect on the further development of physical geography. The first was the European colonial expansion in Asia, Africa, Australia and even America in search of raw materials required by industries during the Industrial Revolution. This fostered the creation of geography departments ...
