Agricultural suitability of rendzinas in Poland
Smreczak Bożena | Jadczyszyn Jan | Kabała Cezary
The agricultural value of rendzina soils depends on many factors, including type of parent rock, texture of arable layer, admixture of post-glacial materials and occurrence of coarse fragments. Over 97% of rendzinas in Poland are arable soils, and less than 3% are under permanent meadows and permanent pastures. Rendzinas are soil of high production potential for agriculture. Almost 75% of them were included in the wheat complexes (from 1 to 3) while about 10% are weak and very weak rye soils (complex 6 and 7) in Polish land suitability system. Groups of rendzinas identified for agricultural purposes and the principles of their identification were established on 1950s and 1960s when bonitation maps and soil-agricultural maps were prepared. These principles have not changed so far, therefore the purpose of the work was to describe the divisions of these soils and the characteristics of their properties on the example of arable soils based on the available data.
