Laboratory and field testing of an automated tension infiltrometer

Popis výsledku v původním jazyce

Three identical newly developed automated tension infiltrometers (Špongrová et al., 2009) were tested in the laboratory and in the field. In the laboratory, the infiltrometers were used on a uniform sandy loam profile prepared in a large soil tank. The measured steadystate data were used to determine the hydraulic conductivity near saturation, K(h), at 8 tensions ranging from 1 to 13 cm using the analytical method proposed by Reynolds and Elrick (1991). In addition, transient cumulative flow data were used to determine the soil hydraulic functions via inverse modelling using the numerical model HYDRUS-2D. Analysis of variance showed that the analytical and numerical methods did not differ from each other within the tension range used in this study. Thetension infiltrometers were subsequently used in the field on a sandy loam soil to characterise five different tillage treatments (conventional plough (CP), shallow plough (SP), minimum tillage (MT), direct drill (DD), and no-treatment (
