Abstract Many factors affect the quality of crops during their growing, and the chief factor the authors are concerned about is the soil and its influence on the rice quality. Based on an analysis of the nutrition composition of rice, the authors infer that there exist a set of characteristic elements that affect the rice quality, thus converting the agriculture problem to a geochemical problem. At the same time, according to the distribution features of the characteristic elements in soil, the authors deduce the distribution of rice quality, which can serve agricultural planning and further processing.
