Investigations of microbial origin of karst corrosion of soils depending on different temperatures
Zambo L. , Horvath G. , Telbisz T. ,
Abstract:
The acids accumulating in soils and controlling the solution of carbonates including the predominant CO2, mostly derive from three processes: i) root respiration of higher plants; ii) decomposition of soil organic matter by microorganisms (microbiota) and iii) other decomposition processes not associated with microbial activities. The solution effect under rendzina soils is primarily used for the dissolution of the enclosed limestone fragments and thus here the solution of bedrock is of limited scale. Below karst soils of high clay content the corrosion of bedrock is more intensive than under rendzinas. On the whole, the amount of carbonates dissolved and transported Into the depths of the karst is smaller than below rendzinas. In each soil type studied the solution caused by microbial activities manifold exceeds the rate of solution resulting from temperature factor but there is a manifest dropping trend from rendzina to clays
