The low soil fertility in semi-arid land requires effective soil improvement measures. To elucidate a possible relationship between dominant minerals and organic materials that improves soil fertility in semi-arid land, several experiments is carried out using kaolinite and urea. The reaction rate of urea-kaolinite complex is determined using XPS and XRD. It is confirmed that the intercalated urea is easily released from the structure of urea-kaolinite complex after dissolution experiments. Soil-forming minerals and native organic polymer compounds which contain nitrogen distributes in semi-arid soil. We will carry out a study at semi-arid land whether complexes will be able to support more efficient agricultural productivity and to determine the applicability of the results obtained to low-fertility areas.
