The methodology for detennining production potential of agricultural and wooded lands in the land cadastre land capability evalvation

摘要

This diploma thesis thoroughly presents the methodology for determining production potential of agricultural and wooded lands - land capability evaluation - in the land cadastre. Land capability evaluation began to be introduced in the 1970's, with Slovenia taking the Austrian and the German system as an example. For better understanding of the topic, the diploma thesis also puts great emphasis, beside the characteristics of the soul, on soil types, which can be found in Slovenia. In the continuation, a presentation on how land ratings in the land cadastre were established in Slovenia, and are nowadays administered and determined. In the practical part, a land capability evaluation for the three chosen field study examples (the Mengeš field) was conducted, based on the current methodology for land rating in the land cadastre. For the chosen study fields, the land ratings points from the land cadastre were compared with the land ratings determined on the basis of field study inspection and soil analysis. We reached an interesting conclusion. Although we had a limited sampling, it was obvious, that the land ratings determined in the fields highly differ from the land cadastre data in the cases, where the land has been object of use change in the nera past (in our case from forest to field). This is logic due to methodology of introduction of land quality ratings in the land cadastre based on the old land cadastral classification data.
