Lysimeter Station Wagna
Installing lysimeters in summer 2004

Figure 6: Field after being ploughed
  • Both fields are ploughed down to a depth of 25 cm.

A tractor must not drive over the lysimeter, only the plough may move over the vessel.

As the soil is not homogeneous (see figure 6), the topsoil around the lysimeter container has to be exchanged manually.

• Fields are harrowed and catch-crop (sunflower, vetch and clover) is sown.

• Position of the vessel has to be determined.

• The mobile ring is put on the inner cylinder and surrounding soil is dug away to remove the wooden ring between the outer and inner cylinders.
