Soils form the foundation for agriculture and are changed by farming through active management unintentionally. Soil change from ranges wholesale transformation to ephemeral subtle modification. The archaeological record of early agricultural systems holds information about soil on centurial millennial scales, with important implications long-term condition land use sustainability. Knowledge can also be inferred soils, including strategies in dynamic, challenging environments. This paper...
Abstract Research on soil fertility is presented in the context of runoff agriculture, a venerable farming system that has been used for millennia arid to semiarid regions, where water major limiting resource crop production. The agroecology was studied with Zuni evaluate nutrient and hydrologic processes, management, maize productivity, quality some oldest recognized fields United States. This ancient Southwest agriculture functioned without conventional irrigation or fertilization by...
Abstract Farmers in the Zuni area of semiarid American Southwest have successfully cultivated maize and other crops for over three millennia without using artificial fertilizers. agricultural fields are among oldest, more or less continuously areas United States. Traditional agriculture is based on runoff farming, a system whereby organic‐rich sediment generated small watersheds captured directed onto crop use. We conducted study to compare soil properties associated with paired unpaired...
Abstract A series of laboratory experiments were conducted in an effort to understand why magnetic field gradient survey techniques failed detect hearths at a prehistoric archaeological site southern California. The study used various methods environmental magnetism examine the effects exposing soil samples temperature 650°C over period 26 h. Results indicate that failure was associated with reduction susceptibility below background levels within hearth soils. This due high‐temperature...
ABSTRACT To mitigate saltwater flooding, the waterfront and downtown areas of Port Angeles, Washington were built‐up with up to 8 m anthropogenic fill beginning in 1913. Shoreline modification continued into present as this important natural deep‐water harbour along Strait Juan de Fuca was developed for maritime industries. This other historical activities obscured at least two historically occupied villages burial sites indigenous Coast Salish Klallam people. Since these archaeological...
Maize has sustained the Zuni and other people in arid American Southwest for many generations. In traditional dryland agricultural system, fields are carefully placed on valley-edge landforms to tap into watershed hydrologic ecosystem processes. these geomorphic positions, field soils managed receive supplemental water nutrients crops by retaining storm runoff transported from adjoining uplands. Crop experiments were conducted examine effects of maize (Zea mays) productivity. Productivity a...
Over twenty years of archaeological research in the Ballona wetlands, California, USA, has provided opportunity to reconstruct how settlement responded landscape change this dynamic environment over last 8000 years. Analyses stratigraphy, radiocarbon dates, and paleoecological indicators (foraminifera, ostracods, molluscs, diatoms, silicoflagellates, pollen) from core samples indicate that sea level rise caused shift a bay at mouth Los Angeles River lagoon by about 7500 cal BP. As gradually...
