Agroecological regionalization on the basis of suitability for crop cultivation: example of Komárom county 1. [antikvár]

In Hungary the century-old, outdated 'Goldkrone' land evaluation, based on cadastral net income, is now being replaced by a new system. The new evaLuation system is launched by a government act and being introduced in two phases. In the first phase the qualities of the habitat limiting possible ecological yield are evaluated which are relatively constant components of the value of habitat. The result of this agricultural habitat evaluation is the score value of habitat going to replace the old land value index expressed in net income in the land registry. The other, relatively fast changing, component of the score value of habitat is to be calculated through economic land evaluation. However, there is no established method for such evaluation yet. Although promising experiments of elaborating complex land evaluation methods (BENET, I. - GÓCZÁN, L. 1973, a,b; NÉMET, L. 1970; SZŰCS, I. 1980a; FEKETE, F. 1984) taking into consideration the ecological differences in habitats (unlike the previous methods), have been made in the last two decades, they do not meet all the requirements of a modern land evaluation, since they do not include the land value component derived from the location-dependent land rent. Calculating this location-dependent rent is ráther difficult in Hungary. On the one hand, state purchase prices do not include transport expenses, on the other hand there is no appropriate agroecological régiónálization in the country which could render this calculation possible. The lack of agroecological regionalization has a disadvantage to the central planning of agriculture, viz. the elaboration of a rational land use model of the country required by a government decree. 2. CONCEPTS FOR DEUMITING AGRICULTURAL MICROREGIONS Research workers undertook to set up an up-to-date agroecological microregionalization methodology, which is presented in tnis report and applied to one of the counties of Hungary. István LÁNG, the secretary generál of the Hungárián Academy of Sciences conducted a significant research project ("The agroecological potential of Hungárián agriculture by the turn of the millennium" 1979-82 - LÁNG, I. et. al. 1983) containing an agroecological régiónálization of Hungary (GÓCZÁN, L. NEMERKÉNYI, A., 1980), but it was actually the adjustment of the boundaries of the new physical geographical mesoregions (PÉCSI, M. - SOMOGYI, S. 1980) to the administrative divisions. True agroecological boundaries were only dominant in the case of very prominent ecological contrasts. Naturally, physical geographical regions cannot be identified with agroecological regions. The former represent more or less 'homogeneous' areas to the totálity of physical geographical factors;
