摘要：The paper reveals hydrologic conditions for growth of Norway spruce young stands on recent immission salvage clear-cut experimental catchment in the late 1980s using pattern of water balance. The pattern was created on the basis of two elementary runoff plots with different soil water conditions. Modelling was based on measurement of suction pressures and hydraulic heads on both plots. The elementary runoff plots were examined within the experimental catchment that was treated with reconstruction of drainage system and addition of sporadic open ditches in July 1996. The model of hydrology balance was presented and verified for 2007–2009 growing periods. The hydrology balance was based on measurements and budget calculations of capillary and semicapillary soil water and gravitation water in aeration zone. Results acquired after hydrological and silvicultural catchment stabilization proved that during dry periods young spruce stands were supplied with water from deeper moist soil horizons, and during wet periods the soil was well drained by soil macropore system without waterlogging.
