Photograph of after feed crops failed, these 1200 acres were seeded in 1942 to blue and sideoats grama and buffalo grass, with sprinkling of little bluestem. This is usef for fall and winter grazing at rate of 15 or 16 acres a head. Mixed upland site in good, approaching excellent condition. In picture is SCS Tech, Z.V. Gordon checks growth.

Photograph of bindweed area at the edge of a wheat field. This area is uncontrolled and is in excellent condition. It is in a low spot where it received enough moisture to encourage growth. If not contolled it will spread rapidly into the ajoining wheat field and cause much damage to the wheat. It is resistant to poisons and can be controlled only by constant tillage. It will kill out other vegetation as it increases.
