Soil Survey Of The Islands Of Aguijan Rota Saipan And Tinian Commonwealth Of The Northern Mariana Islands

This book provides an overview of the distribution, properties, and function of soils in the U.S., including Alaska, Hawaii, and its Caribbean territories. It discusses the history of soil surveys and pedological research in the U.S., and offers general descriptions of the country’s climate, geology and geomorphology. For each Land Resource Region (LRR) – a geographic/ecological region of the country characterized by its own climate, geology, landscapes, soils, and agricultural practices – there is a chapter with details of the climate, geology, geomorphology, pre-settlement and current vegetation, and land use, as well as the distribution and properties of major soils including their genesis, classification, and management challenges. The final chapters address topics such as soils and humans, and the future challenges for soil science and soil surveys in the U.S. Maps of soil distribution, pedon descriptions, profile images, and tables of properties are included throughout the text.

At the Unai Bapot Site of the Mariana Islands, new excavation has clarified the oldest known instance of a residential habitation prior to 1500 B.C. in the Remote Pacific, previously difficult to document in deeply buried layers that originally had comprised near-tidal to shallow subtidal zones.
