Local Soil Name: Fekete Nyirok

Note: Fekete means black; Nyirok means moist, humid. Fekete Nyirok is the traditional name for soils with very high clay content and the adjective "fekete" before "nyirok" refers to the quality of the clay (smectite), and to the strong process of humus formation in the soil. In the Hungarian classification the soil belongs to Fekete Nyirok, which are formed on volcanic/eruptive parent materials and are characterised by strong humus formation and weak leaching processes (STEFANOVITS, 1992).
