ANALYSIS OF CHANGES IN OFFICIAL AGRICULTURAL LAND PRICES IN THE CR IN YEARS 2009-2017

Annotation: The main objective of the paper is to evaluate quality changes of land resources on re-evaluated/updated areas of the CR in chosen time period. The main goal was divided into partial goals: a) To find out the change average official land price /OLP/(economic indicator of agriculture soil quality) per cadastral areas and to verify statistical significance of impact of quantitative and qualitative agriculture land changes on land price rate. b) to identify the main reasons for the degradation of agricultural land. The research uses primary data from Czech Office for Surveying, Mapping and Cadastre (2008-2016), OLP per cadastral area in Decree of the Ministry of Finance on determining land prices (2009-2017) and secondary data from Ministry of Agriculture. The data were processed using comparison methods, regression and correlation analysis, and weighted means method, resulting in a proposal of quantitative degradation factor. There was OLP Index of updating cadastral areas in five regions in the interval (0. 99; 0. 54) between years 2009-2014. The main causes of the decline of cadastral OLP by more than 10 % (35.76 % of all negative changes in five analysed regions) were: Erosion processes with loss of fertility loess soils, economic activity on the slopes (42.9 % of cases), more detailed soil evaluation exploration (38.6 %), increasing the slope of agricultural land due to building modifications (8.6 %), inappropriate agro-technical practices and inadequate crops structure on the agricultural land in combination with land profile (7.1 %). It can be stated, that excessive decreases of quality agriculture land and loss of land quality due to anthropological processes in production important areas have a significant influence on the change of land quality. Based on the soil evaluation exploration results: There was a decrease of regional OLP (region OLP index < 1) in four regions in 2009-2014. During the period 2016 to 2017 the OLP declined already in nine regions.
