Anthropogenic Soil Change in Ancient and Traditional Agricultural Fields in Arid to Semiarid Regions of the Americas
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, with important implications for long-term soil condition and land use sustainability. Knowledge of earl…
A Maize Experiment in a Traditional Zuni Agroecosystem
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 and nutrients for crops by retaining storm runoff transported from adjoining uplands. Crop experiments…

Living in the Ballona Wetlands of the Southern California Coast: Paleoenvironmental Reconstruction and Human Settlement
Over twenty years of archaeological research in the Ballona wetlands, California, USA, has provided the opportunity to reconstruct how settlement responded to landscape change in this dynamic environment over the last 8000 years. Analyses of stratigraphy, radiocarbon dates, and paleoecological indicators (foraminifera, ostracods, molluscs, diatoms, silicoflagellates, and pollen) from core samples indicate that sea level rise caused the Ballona to…
Assessing Coastal Landscape Change for Archaeological Purposes: Integrating Shallow Geophysics, Historical Archives and Geomorphology at Port Angeles, Washington, USA
To mitigate saltwater flooding, the waterfront and downtown areas of Port Angeles, Washington were built‐up with up to 8 m of anthropogenic fill beginning in 1913. Shoreline modification continued into the present as this important natural deep‐water harbour along the Strait of Juan de Fuca was developed for maritime industries. This and other historical activities obscured at least two historically occupied villages and burial sites of the indig…
Biogeochemical studies of a Native American runoff agroecosystem
Research on soil fertility is presented in the context of runoff agriculture, a venerable farming system that has been used for millennia in arid to semiarid regions, where water is a major limiting resource for crop production. The agroecology of runoff farming was studied with the Zuni to evaluate nutrient and hydrologic processes, management, maize productivity, and soil quality in some of the oldest recognized fields in the United States. Thi…
Thermally activated mineralogical transformations in archaeological hearths: Inversion from maghemite γFe 2 O 4 phase to haematite αFe 2 O 4 form
A series of laboratory experiments were conducted in an effort to understand why magnetic field gradient survey techniques failed to detect hearths at a prehistoric archaeological site in southern California. The study used various methods of environmental magnetism to examine the effects of exposing soil samples to a temperature of 650°C over a period 26 h. Results of the study indicate that the failure was associated with a reduction in soil ma…
Amazonian dark earths: Origins, properties, management
Anthropogenic influences on Zuni agricultural soils
Farmers in the Zuni area of the semiarid American Southwest have successfully cultivated maize and other crops for over three millennia without using artificial fertilizers. Zuni agricultural fields are among the oldest, more or less continuously cultivated areas in the United States. Traditional Zuni agriculture is based on runoff farming, a system whereby runoff and organic‐rich sediment generated in small watersheds are captured and directed o…
