Soils <br /> a. The dominant soils are deep or moderately deep with medium <br />' textured profiles. Moisture intake is moderate. Field <br /> capacity for storing moisture is high, but depth of penetra- <br />' tion and ability to give up moisture to plants is not as <br />great as in the sandier soils. Short grasses are adapted to <br /> these soils because of their fibrous and relatively shallow <br /> root systems and their ability to go dormant during dry <br />' ' spells. Mid grasses are scattered throughout the site. There <br /> is high production in good moisture years. <br />1 ~ I ~ ' <br /> <br />' . , - •~~~ <br /> <br /> ', <br />• ~ .. <br /> <br /> - - <br />
