Anthropogenic Effects on Soil Quality of the Las Capas Irrigation System (2015)
DOCUMENT Citation Only Jeffrey Homburg. Fred Nials. James Vint.

A soil quality study was conducted at the Las Capas site to document and evaluate the soil productivity and hydraulic soil properties of this ancient agricultural irrigation complex. This site presents an unprecedented opportunity to study the complete configuration and evolution of the oldest irrigation system documented in the Southwest to date. Mechanical stripping permitted earthen berms around small field grids to be identified so that soil samples could be collected in relation to nearby...

Vanishing River Volume 4: Chapter 09: Environmental Variability and Agricultural Economics along the Lower Verde River, A.D. 750 - 1450 (1997)
DOCUMENT Full-Text Carla R. Van West. Jeffrey H. Altschul.

In Chapter 9, Van West and Altshcul examine late prehistoric period agriculture in the Transition Zone of central Arizona, and consider how agricultural production influenced population zone in this area. They begin with a description of the Transition Zone’s environmental context. They then present evidence for prehistoric agriculture in the LVAP project area. These authors use these data to model potential agricultural productivity in Horseshoe Basin. Next, they model the population sizes on...
