Discrepancy in climatic zoning of the current soil productivity evaluation system

Popis výsledku v původním jazyce

Pedologic-ecological estimation in the Czech Republic (Central Europe) meansdetermination of land agronomic productivity and its economical pricing and is expressedas a five position numeral code and mapped as iso-lines. The first position of the code isthe climatic region representing approximately the same conditions for agricultural plantgrowth and development. This climatic regionalization was based on the climatic datafrom 1901-1950. Currently, there is the need to update their existing zoning due to thetechnological progress of measurement and development of climate models including estimationof future climate. The aim of the paper is (i) to apply actual climatic datato climatic regionalization and (ii) to estimate what climatic conditions are relevant foractually valid climatic regions. The original methodology currently enables us to unequivocallyclassify only 17% of the entire territory of the Czech Republic (and 18% of Czechagricultural land). A substantial part of the territory does not fit neatly into individualclimatic regions. Subsequently the actually valid ranges of climatic characteristics of individualclimatic regions were determined. The GIS layers of individual climatic variablescomputed with data from 1961-2010 were one by one covered by GIS layers of individualclimatic regions based on data from 1901-1950. Interval ranges of climatic region variablesdetermined in this way are valid for the period 1961-2010. The upper limit of airtemperature sum above 10oC and annual air temperature in most of the climatic regionswas significantly shifted up in 1961-2010. An increase in precipitation is noticeable in wetclimatic regions. Moisture certainty in vegetation season and probability of dry vegetationare the most problematic in terms of Estimated Pedologic-Ecological Units (EPEU)climatic zoning. This should be taken into account when fixing the official soil price
