These soils are on very gently to gently sloping plains. Slope ranges from 0 to 5 percent. The mean annual precipitation is 457 mm (18 in) and the mean annual temperature is 16 degrees C (61 degrees F).
Depth to well-drained caliche rock varies across the Rowland Taylor property ranging from 33 inches to rock in shallower areas and greater than 60 inches to rock in areas with deeper soil.
