In the Mátra, there are brown forest soils, adequate with the bedrock, formed on andesite. On areas at the foot of the mountains, chernozem-brown soil alternates with brown earth. At higher altitudes, these are succeeded by clay-inwashed brown forest soil that can become podsolised to varying degrees. On the loess layer that covers the western side of the mountain range, chernozem-brown forest soil can be found.
