The sericea was fertilized with 650 lbs. per acre of rock phosphate which was drilled into the soil. In 1962 the sericea was plowed up, 2 ½ tons of lime and 100 lbs. of 10-20-10 fertilizer per acre was applied and Greenfield Bermuda was planted. That fall the Bermuda was overseeded with vetch, rye and fescue and 125 lbs. of 10-20-10 fertilizer was applied. No fertilizer has been applied since that time. Estimated forage yield was 4 tons per acre in 1966."
