Abstract: Through analyzing spatial distribution of soil trace elements (Fe, Mn, Cu, Zn, B) of topsoil in farmland in Ganzhou District, the author took a research on the content of soil trace elements in the whole region from both horizontal and vertical directions, and drew a conclusion about the sufficiency and deficiency situation of the content of soil trace elements in this area by comparing them to the national soil trace element standards. The main conclusions were as follows: in the horizontal direction of 0-5, 5-10, 10-20 cm soil layer, the distribution characteristics of soil trace elements were quite different, the main characteristics showed that there was a decreasing trend of soil trace elements distribution from northwest to southeast and low in the middle and high on all sides. From the vertical direction, the average content of soil available Fe and Zn showed a slow upward trend with the increase of soil depth; the distribution of the average content of soil available Cu and B decreased with the soil depth increase; soil available Mn was high in both top and bottom layer and low in middle layer; the vertical distribution characteristics of trace elements in some towns were different from the whole region. The contents of soil available Fe, Mn, Cu, Zn in most of the towns were at moderate level, soil available B belonged to deficiency level. The author suggested that B fertilizer should be applied in this area for future planting.
