A characteristic feature of the mountain soils is the occurrence of a greater amount of the acidic and weakly decomposed organic matter (mor/moder). It usually forms deep humic horizons and greatly influences the formation of the alpine vegetation habitats as well as the direction of the soil forming process. A comparison of the organic matter properties of the mountain soils formed on various bedrock in the Carpathian Mts. (sandstones, Flysch slates - Bieszczady Mts.; limestones, granitoides - Tatra Mts.) and in the Massif Central (volcanic ashes, andezites, dolerites - Monts Dore) (Tab.l). Characteristic features of all the researched soils are as follows: depth of the humic horizons and similar properties of the organic matter (Tab. 2-3). The humic horizons are usually around 30 cm deep with the 30-50% amount of the organic matter in the ectohumic horizons and 10-20% in the endohumic horizons. In the ectohumus horizons fulvic acids prevail over the humic ones. The humification index for the ectohumic horizons is around 0.1-0.4 and it means a considerably small degree of changes of the accumulated organie matter what is characteristic for the humus of the mor/moder type formed in the mountain regions. The organic matter formed in the cool and humid mountain climatic conditions shows properties of the decreasing pace of the humification processes. Regardless the bedrock all the presented soils can be characterised with similar humic horizon properties. (original abstract)
