Soil Water Holding Capacities for Selected Arizona Counties (ACIS)

Soil Water Holding Capacities for Selected Arizona Counties

Following is a compilation of the most common irrigated soils and their water holding capacities by county. The units for the water holding capacity is in inches of available water for plants per foot of soil depth. For example, a Grabe Loam in Cochise county holds 1.7 inches of available water for plants in the first foot of soil. This soil holds more water than this but not all of it is available to plants.

The data for these soils was obtained from the published Soil Surveys of the Soil Conservation Service (SCS). The water holding capacities are average. Soil type and texture varies greatly and many times no one soil defines a field. The user can contact their local Cooperative Extension Agricultural Agent or the local SCS office for help in determining the type and textures of the soils in their particular fields.
