Much of the new land being developed in Glenn County is comprised of Tehama and Kimball series soils, which, because of their structure and other profile characteristics, are often considered problem soils. Alfalfa hay yields on these soils range from less than 4 tons to 8½ tons per acre, depending on management. The alfalfa is generally rooted in less than 2 feet of soil; in summer, primary feeder roots are in a zone usually below 2 inches and above 12 inches.
