Article
Interest in understanding America’s soils goes back to prehistory with the Native Americans. Following European settlement, notable individuals such as Thomas Jefferson and Lewis and Clark made observations of the soil resource. Moving into the 1800s, state geological surveys became involved in soil work and E.W. Hilgard started to formulate ideas...

Soils form the foundation for agriculture and are changed by farming through active management and unintentionally. Soil change from agriculture ranges from wholesale transformation to ephemeral and subtle modification. The archaeological record of early agricultural systems holds information about soil change on centurial to millennial scales, wit...
Chapter
Civilization is tied to soil through our reliance on agriculture. As early civilizations rapidly developed new agricultural strategies, their knowledge of soil and soil management expanded as well. Major innovations that appeared over the first few thousand years of agricultural production included irrigation, terracing, plows, contour tillage, and...

The LSU Campus Mounds (16EBR6) are a two-mound group situated in the heart of the Louisiana State University campus in Baton Rouge. Mound A is about 5.3 m tall and 39.6 m in diameter, and Mound B is about 5.2 m tall and 36.5 m in diameter. Investigations by Neuman (1992), Homburg (1992, 1993), Mann (2009, 2012), and Saunders and Ellwood (2018) were...

Maize has sustained the Zuni and other peoples of the arid American Southwest for more than four millennia. In Zuni dryland agriculture, fields on alluvial fans and other valley-edge landforms are managed to receive supplemental water and nutrients by retaining storm runoff and associated sediment and organic material transported from adjoining upl...

Project Location: The project area is located in the former Ballona Lagoon, a prehistoric wetland complex in west Los Angeles that is known collectively as the Ballona. This area is today bound roughly by Playa del Rey to the west, Marina del Rey to the north, the Ballona Escarpment (a high bluff ) and Del Rey Hills/Westchester Bluffs to the south,...

Our study examines the combined effects of future climate change and the construction of a reservoir for gold mining operations on the carrying capacity of agricultural lands in the Sabodala-Tamboucanda region of southeastern Senegal. Analysis of physical and chemical soil properties of agricultural fields in southeastern Senegal was completed to a...

Maize has sustained the Zuni and other people in the arid American Southwest for many generations. In the traditional Zuni dryland agricultural system, fields are carefully placed on valley-edge landforms to tap into watershed hydrologic and ecosystem processes. In these geomorphic positions, field soils are managed to receive supplemental water an...

Pedoarchaeological studies were conducted at the Las Capas and Sunset Road sites in the Tucson Basin of Arizona in order to document and evaluate soil productivity and hydraulic soil properties of ancient agricultural irrigation systems. These ancient irrigated fields are on the margin of the Santa Cruz River floodplain, between two allu-vial fans...

The beginning of the 20th century through the 1970s were good times for soil science in the USA, with relatively strong funding and overall growth in the profession. However, the soil science discipline in the USA hit hard times in the 1980s and 1990s. Federal funding for soil survey work began to decline as did student numbers in university progra...

The USA has had arguably the strongest and certainly the most extensive soil mapping program in the world. Yet many of the developments in digital soil mapping (DSM) occurred outside the USA from the late 1970s through the 1990s. This presentation attempts to explore why the USA has differed from many of the international trends in DSM. Much of the...

In September 2016, a geoarchaeological investigation was conducted by LSA to determine if buried cultural deposits of the prehistoric/ethnohistoric village site of La Rinconada de Jamo (La Rinconada), CA-SDI-5017, or any other archaeological sites are present within the proposed project area for Sewer Group 786 and Sewer and Water Group 955. The pr...

The purpose of this chapter is to describe the geologic and geomorphic setting of the Mescal Wash site. The Arizona Geological Survey (AZGS) recently completed 1:24,000-scale geologic mapping in the area encompassing the site. Therefore, it seemed appropriate that the AZGS and SRI collaborate on the geoarchaeological investigations of the Mescal Wa...

The geoarchaeological record holds key information about past land use and its impact on soils and environment. Among agents of anthropogenic soil change, agriculture’s impact on soil is immense in magnitude, spatial extent, and duration. Agriculture has profoundly altered soil properties, processes, and formation pathways world-wide since its ince...

Around the world, archaeological predictive models are increasingly important to heritage management by estimating where sites are likely to be located, particularly in un-surveyed areas. Northern Mongolia is well known for its archaeological resources, particularly Bronze Age and Early Iron Age sites, but vast areas remain to be surveyed. This pos...
Presentation
Full-text available
It is importance to study long-term anthropogenic soil change because soil is a critical resource that is basically non-renewable. We are in a time of accelerated human soil-landscape change. Data from ancient agricultural sites provide truly long-term perspectives on anthropogenic soil change.

Small pockets of land suitable for runoff agriculture exist along the US 491 corridor, but the best farm land is located along the flanks of the Chuska Mountains to the west. This finding supports Benson’s contention that most of the Southern Chuska Valley is less suited for agriculture than land at the immediate base of the Chuska Valley. Relative...
