O článku:
The article presents spatial and temporal variability of soil moisture of the upper organic soil horizon of a mountain forest soil. The measurements were carried out at two sites in the Jalovecký creek catchment, the Western Tatra Mts. in vegetation season 2013. Depth of the soil profile indicated by geophysical measurements (electrical resistivity and induced polarization tomography) is approximately up to 0.7–1 m. Volumetric soil moisture was measured by the Delta T Devices Wet-2 sensor device in the uppermost soil layer up to 7 cm soil depth. The largest values were measured at the end of May, the smallest ones during extremely dry summer period in August. Spatial soil moisture variability was higher than its temporal variability. At the site Červenec-forest the highest spatial variation of soil moisture was measured on the 31st of May in the range of 0.139–0.612 cm3⋅cm-3.The variability was smaller at the second site Pod Lyscom where the data series was shorter. It varied in the range of 0.073–0.343 cm3⋅cm-3 on the 24th of July. Increasing soil moisture lead also to increase of spatial variability on research plots expressed by standard deviation. Spatial correlation among individual points (mostly up to 4 meters) was detected only for the Červenec-forest site. Laboratory analyses indicate that maximum measured soil moisture of about 0.6 cm3⋅cm-3 is realistic and increase of spatial variability during wetter periods is caused by faster wetting and drying of the organic layer.
