Photograph of Neal Stidham, SCS Technician, and Mack Keathley standing in a field oak trees and brush which 80% was killed via aerial spraying in 1956 and 1957. This improved said land going from poor condition land to good condition. People shown in photo go as followed from left to right: 1. Neal Stidham, 2. Mack Keathley. The back of the photograph proclaims, "Brush Control. Aerial spraying, oak timber sprayed late June 1956 and 1957. Two years after second application still 80% kill on oak trees and brush. Trees die the year following chemical application. Range condition class before treatment was Poor Condition. Now in Good Condition and being used. SCS Technician Neal Stidham and Mack Keathley in photo. See Ok-684-9."

The back of the photograph proclaims, "Rotation Hay and Pasture. 4 acre strip of weeping lovegrass used as wind-strip and rotation hay and pasture on 7x AB Pratt fine sandy loam soil. Reinhart harvests seed and pastures these strips in the winter with small grain and vetch. Seed harvested 6/20/59 yielded 800 lb. seed on the 4 acres. After 5 years the strips are plowed up and other strips are seeded to control wind erosion."

Photograph of 7X-AB Pratt Fine Sandy Loam soil. Reinhart using a rod weeder fastened to a chisel type instrument. Chisels loosens soil and rod rotates in reverse which lifts all vegetation up from 4 inch depth. On tighter or more loamy soils this machine is used after one-waying for the second operation.
