WebInfiltration is the process of water entry into the soil. The rate of this process, relative to the rate of water supply, determines how much water will enter the unsaturated soil zone, and how much, if any, will runoff (Hillel, 1982).It is usually measured by the depth (in mm) of the water layer that can enter the soil in 1 h.The infiltration rate decreases as the soil … Web10 jan. 2024 · In the group of carbonate soils, Leptosols (38%) were also the most numerous, followed by Cambisols (33%) and Phaeozems (21%). In addition, this group included Histosols (5%), Gleysols (2%) and Stagnosols (1%). Thus, the Leptosols (65%) dominated among all the studied soils, of which 2/3 were Lithic Leptosols.
