Productivity of Huntington, Waynesboro, and Dickson soils for corn

The objectives of the study were outlined to the local agricultural workers before any farmers were contacted. Names of possible cooperators were obtained. When this system proved unfruitful, fields were located by driving through the county. When one of the soil types that had been in corn in 1957 or that might be planted in corn in 1958 was observed the farmer was contacted and his cooperation was solicited
