... at Research Centre Foulum (56°30′ N, 9°34′ E) and in the field at Jyndevad Research Station (54°9′ N, 9°12′ E). The semi-field facilities consist of lysimeters (1 m 2 ) and basins (4.32 m 2 ), both 1.5 m in depth. Three different soils were used for the experiments at the semi-field facilities: Jyndevad soil...

..., and is therefore recommended for predicting variations in soil-gas diffusivity within the vadose zone. Undisturbed soil samples were collected at five soil profiles in Denmark: three large soil bins (lysimeters) at the Danish Institute of Agricultural Sciences at Research Centre Foulum with soil from...

... of colloid size and composition, respectively, on the correlations. Similarly, concentration–turbidity correlations were then developed for soil colloids prepared from a large number of soil samples (37 soils collected from the United States and Denmark). These samples were fractionated into different size...

..., and Jyndevad, and two agricultural fields, Gjorslev and Mammen. For convenience, we refer to the Rønhave, Foulum, and Jyndevad soils as lysimeter soils , and the Gjorslev and Mammen soils as field soils . Soil site locations in Denmark, basic soil characteristics including soil texture, and measurements...

... of that density. More specifically, the study investigated the effects of soil density and soil type on D p / D o and k a based on data from vadose zone profiles across Denmark, including soils from urban, agricultural, and forest sites as well as a final landfill cover soil. Density-corrected model...

... that erroneous measurement of the SWC can lead to highly inaccurate simulation of the soil water balance. Three sets of soil samples emanating from three geographical regions (Denmark, Sri Lanka, and the United States) were used to illustrate the applicability of the VSA. The first set comprised six...

As shown in Fig. 8 , the TRWR model predictions at high pF (lines for pF = 4.2 equal to the permanent wilting point and pF 6.0 approximately equal to the ambient air-dried condition) encompassed the measured potential WR, except for a sand...

.... Jensen and Mantoglou (1992) applied the theory of Mantoglou (1992) to predict the mean behavior and the variance of the matrix potential and soil moisture content determined at the Jyndevad field site (100 by 50 m). A total of 24 sampling points for each of the three soil layers was used to derive...
