Abstract:In 2015, the International Year of Soils(IYS), a historical review on soil chemistry research provides scientific basis for the long-term development of soil science in the new era. Based on the literature review of the characteristics, current status, and advances of recent studies in soil chemistry science. It also provides prospects on the future development trends in this area and priorities. The conclustion is that macro-monitoring on soil needs to be based on the understanding of soil microscopic mechanism. After the concept of"earth's critical zone"was raised, the great progress made in understanding in-situ observation at atom and molecular scale, lays the foundation for the rapid development in soil chemistry research in the most recent decade. The cross-disciplinary integration between soil science and biology, environmental science, chemistry, geology,etc., especially biology, further developed and expanded the academic field of traditional soil chemistry, facilitating the formation and development of new theories in the earth's critical zone.
