The Paxton soil series was established in Worcester County, Massachusetts in 1922, and is named for the town of Paxton where it was first described and mapped. ==Taxonomic classification== Coarse-loamy, mixed, active, mesic Oxyaquic Dystrudepts. Paxton soils are in the Inceptisol soil order of soil taxonomy. The term "coarse-loamy" indicates that the soil has less than 18% clay and at least 15% or more particles that are fine sand or coarser. The term "mixed" indicates no single mineral is over 40 percent. The term "active" represents a ratio of the cation-exchange capacity to clay of the pedon. The term "mesic" indicates the soil developed in a temperature between 8 and 15 degrees C. The "Typic Dystrudepts" are typical profiles () with low pH () with an udic soil moisture regime and are within the Inceptisol order (). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Paxton (soil)」の詳細全文を読む スポンサード リンク
