   Soil micromorphological study was performed to demonstrate impact of soil plant cover on soil micromorphology and soil porous system that is reflected in a shape of soil hydraulic properties. Soil samples were collected from soil pits surviving nature-close beech forest and in production spruce forest, an also in area with dead forest with grass cover of soil. Despite of varying thickness of soil horizons, the soil hydraulic propeties were similar in different forests. In contrast, the soil hydraulic properties of soil horizons under the grass cover showed higher retention ability. Retention ability reflects soil micromorphology and soil porous system of studied horizons. Humic horizon under the forest show higher porosity and consequently lower retention ability. Humic horizon under the grass cover show more compact structure, lower porosity and higher retention ability.
