| Popis: | The aim of this paper was to analyse water dynamics in the soil from tensiometer data in two different plots, one with bare soil and another with geotextiles and grass, correlating the information generated in the study concerning biotextile efficiency in soil moisture maintenance, which is essential to vegetation development and to the recovery from and control of erosion. Tensiometers were installed on the bare soil and grass plots at different depths (15, 30, 80 and 120 cm), and the respective readings were taken with a digital tensimeter. Water dynamics inside the soil can be demonstrated by matric potential data from pressure differences. A large difference between the bare soil and grass plots was demonstrated by matric potential medium values at depths of 15, 30, 80 and 120 cm during monitoring. |
