Photograph of bindweed control. Jim Gassoway, U.S. Borax & Chemical Corporation, demonstrates the use of a light weight shoulder-sling hand spreader for use of granular weed killers. This type of spreader is commercially available and easy to operate. Turning the crank and walking at a normal pace will accurately cover a 6-foot swath. The spreader is especially recommended for the use of Benzabor weed killer in the treatment of small areas less than ½ of an acre. Rate 1 to 1 ½ pounds per square rod. OK-1094-11.

Photograph of Bill Sharpe standing between two fields, which the right side received five tons per acre of applied gypsum, while the left side did not receive any gypsum. This field is near Will Rogers Air Port in Oklahoma City. The back of the photograph proclaims, "Gypsum Application. Bill Sharpe in photo. Portion of land to left of Bill did not have Gypsum applied. One on right had nearly 5 tons per acre. Before the application this portion of field would not grow anything. The portion where gypsum was not applied was not that bad."
