| ABSTRACT |
| Samples of 21 soil profiles and 165 top soils from an area of approximate 1.5 km2 on red-earthy hill landscape were collected and analysed. The content of Ca, Mg, K, P, Fe, Mn, Zn and Cu in soils relate with the kind of parent material and the position of topography, however, there is great variation due to the local difference of the form of soil utilization. From the difference in spatial distribution of elements content, it is believed that eight kinds of elements are lost by chemical leaching and physical translocation, meanwhile some are added (such as Ca, P, K, Mg) and some mobilized (such as Fe, Mn, Zn, Cu and P) through cultivation, fertilization and irrigation in the soils on the landscape investigated. The sectional differentiation in abundance or deficiency of elements in top soils on the landscape investigated is distinct, which is important for carrying out agricultural management and reasonable fertilization according to local conditions. |
