Possibilities of agricultural soils evaluation in the Czech Republic

In this study, the evaluation of soil quality was realised using the Analytic Hierarchy Process, and the obtained values were integrated with Evaluated Soil Ecological Units (BPEJs). Different maps of the Czech Republic were elaborated with BPEJs classified into five soil protection classes based on the obtained model values (with or without the values for production potential), the ratio of 80% (production potential values) to 20% (model values) or 60% (production potential values) to 40% (model values) and 40% (production potential values) to 60% (model values). The evaluation of BPEJs based on the mentioned criteria showed differences in their classification into individual soil protection classes and possibilities of their use or withdrawal from the agricultural land fund. Compared with the existing categorization of BPEJs into soil protection classes (according to Decree No. 48/2011 Coll.), the use of presented model (plus production potential) values, the ratio of 80 : 20%, 60 : 40% or 40 : 60% (production potential: model) caused the numbers of BPEJs increased in those soil protection classes where the withdrawal of soils from the agricultural land fund is possible only exceptionally or it is possible to use the soils for building purposes only under certain conditions.
