Herstellung von Lysimetern mit Böden in natürlicher Lagerung (Monolith ‐ Lysimeter) als Durchlauf‐, Unterdruck‐ oder Grundwasserlysimeter

Preparation of Polyester Jacketed Soil Columns as Penetration, Suction Plate and Groundwater Lysimeters A simple and cheap preparation technique for long soil monolith lysimeters consists in forming columns of undisturbed soil out from the walls of soil pits by means of a steel cylinder, encasing the column with glasfiber mat and infiltrating this coat with polyester resin. Casing is also possible by simultaneous application of resin compounds and glasfiber as a mix spray. Imbedding of steel slats in the polyester walls facilitates the transport. Descriptions are given how to make use of such columns as simple penetration lysimeters, suction plate, and groundwater lysimeter sets for studies of water and bio‐element balances of the soil.
