The soils collected for the lysimeters were under pastoral agriculture land use and were as follows.
Containers (lysimeters) with capacity of 12 L were utilized in the experiment, filled with 10 [dm.sup.3] of soil of the respective treatment, presenting in the base no zero gravel layer (1 kg) and a sand layer.
Six suction lysimeters were installed at increasing distances downslope of the baits, at 2 m, 10 and 18 m (see Figure 2).
First, concrete lysimeters were constructed and used to measure ET for alfalfa.
Across the study area, two types of soil water collectors (lysimeters) were installed below the majority of the rooting zone (0.36 [+ or -] 0.01 meters [14.17 [+ or -] 0.39 inches]) and directly under vines.
Yang et al [8] quantified water fluxes in large weighing lysimeters, with a fluctuating groundwater table between 1.6 and 2.4 m during the wheat growth period and 0.7 and 2.3 m during the maize growth period, and found that, in a rotation system of wheat and maize, the cumulative capillary upward flux and the deep percolation were 89.6 and 55.9 mm, respectively.
To study undisturbed soil profiles, cube-shaped steel casings (60 cm on a side) were driven into the ground, excavated and used as lysimeters to evaluate the vertical transport of three estrogens.
Lysimeters were installed in nests in the unsaturated zone (above water table) at 90, 120, and 150 cm below the surface near background and drainfield piezometers (Figure 2).
