Lysimeter Station Wagna
Installing lysimeters in summer 2004

Figure 3: Cylinder is put
on the ground
  • The lysimeter cylinder filled with soil is then lifted from the hole, turned round and put on the ground near the pit with the upside down, see figure 3.

• The bottom plate and about 12 cm of the natural soil are removed. 7 suction cups (of different sizes) for collecting seepage water are installed. Soil is replaced by different sizes of filter sand and gravel from top to bottom. This ensures an undisturbed water flow (in case that drainage water occurs despite of water being collected by the suction cups).

• The bottom of the lysimeter is covered with a fleece and a stainless steel bottom plate is welt to the container.At the same time, soil samples of all horizons are taken to be analyzed for different parameters.
