Soil Series
Soil series as established by the National Cooperative Soil Survey of the United States Department of Agriculture (USDA) Natural Resources Conservation Service are a level of classification in the USDA Soil Taxonomy classification system hierarchy. The actual object of classification is the so-called soil individual, or pedon. Soil series consist of pedons that are grouped together because of their similar pedogenesis, soil chemistry, and physical properties. More specifically, each series consists of pedons having soil horizons that are similar in soil color, soil texture, soil structure, soil pH, consistence, mineral and chemical composition, and arrangement in the soil profile. These result in soils which perform similarly for land use purposes. The soil series concept was originally introduced in 1903. Soil series were originally intended to consist of groups of soils which were thought to be the same in origin but different in texture. Soils were thought to be alike in orig ...

All these groups spoke related Arawakan languages. Name Early Spanish explorers and administrators used the terms ''Arawak'' and ''Caribs'' to distinguish the peoples of the Caribbean, with ''Carib'' reserved for indigenous groups that they considered hostile and ''Arawak'' for groups that they considered friendly. In 1871, ethnologist Daniel Garrison Brinton proposed calling the Caribbean populace "Island Arawak" due to their cultural and linguistic similarities with the mainland Arawak. Subsequent scholars shortened this convention to "Arawak", creating confusion between the island and mainland groups. In the 20th century, scholars such as Irving Rouse resumed using "Taíno" for t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
