Photograph of two acre Bermuda grass pasture strip developed from a badly gullied draw. The draw was sloped and sodded in 1938 and now provides grazing at the rate of 1 unit per acre and serves as an outlet channel for 70 acres of terraced and cultivated land. Mr. Fred Bunch states that this pasture strip furnishes better grazing than any of his 28 acres of native pasture on this 160 acre farm. He also states that his soil conservation practices have increased by $1,000 the value of this farm. Terraces were built with the assistance of the old Sentinel Civilian Conservation Corps [CCC] Camp. OK-8467. Meadow development. In the spring of 1940 this 60 acre abandoned, cultivated field was planted to sericea lespedeza. There was formerly a shoulder deep gully where the man I standing and numerous smaller ones covered the area. This year Mr. George Stainer has made one cutting for hay that yielded a ton per acre. It has been heavily grazed since then and another hay crop could be cut immediately (the estimated yield is 1 ton per acre). OK-8628.
