Kuti L., Kerék B. and Tóth T. 2005. Agrogeological characterization of the plain and hilly regions of Hungary. (Hung.) Tájökológiai Lapok. 3:83-97. In order to create the prerequisites of modern land-use, to identify the most appropriate agricultural activities for a given area, and to develop convenient conditions for supporting the agriculture, adequate knowledge of the agrogeological values of the given area is required. It is also important to study and characterize the agrogeological position of the regional units in question. The agrogeological qualification of the plain and hilly regions of Hungary has been perfomed relying on the data and maps of the geological surveying that was carried out during the past decades, by means of agrogeological re-evaluation of the geological data. The lithological map of the surface and near-surface formations was plotted first, followed by the maps showing the depth, the cemical type, and the total dissolved salt content of the groundwater, respectively. These having been completed, further maps were derived from them: irrigability of the area, risk of inland water, and erosion vulnerability. These maps have provided us with the possibility of qualifying and assessing the regions of study. This was done by ranking on a 0-5 scale, the various agrogeological factors occurring in the area, taking into account their positive or negative effect, respectively. The outcome was that the weak and strong points of the regions studied have been unambiguosly established. This facilitates the selection of those plant species, which are the most convenient for the given region, and of the most adequate agrotechnical activities.
