The rational and efficient management of land resources, in the frame of a sustainable agriculture and environment protection, have to be based on the operational, and at the same time, more detailed and accurate knowledge of soil resources. This knowledge is based on soil information obtained by carrying out soil surveys and field research, and by laboratory measurements of main soil physical and chemical parameters. Thus, the basic soil information, consisting primarily of data on soil profiles representative of the study areas is obtained. The objective of this paper is to develop several applications for coupling georeferenced data from Geographic Information System of Soil Resources SIGSTAR-200 with the information of soil profiles from the Soil Quality Monitoring Network 8 km x 8 km. The spatial distribution of existing soil profiles, as well as the distribution of soil types have been studied, and their representativeness is determined. IT applications have been developed to highlight the number of profiles consistent with the polygons containing them, or with the neighbouring polygons. The soil areas that are described by a profile from the soil profiles database (having a profile which is located inside the polygon) are also established.
