Based on the investigation of the agricultural-geological background conditions in the Weifang area the authors have classified the parental materials of soils in the area into three types of near source tele-source and mixed source accotding to the types of source materials and further classified the last type into several subtypes according to the genetic types of the accumulation materials.This classification is in well agreement with that for the Soil subtypes classified by the Weifang soil and Fertilizer Station but is quite different from its soil category classified Loess and the profound influence of the loessy parental materials on the soils in the area are discussed as well.The results of the investigation have shown that there is a wide area for the cooperation(combination)between the geological and agricultural sectors.
