Abstract
An improved lysimeter is described for collecting soil water which is truly representative of the soil water contained in the soil at selected locations. The lysimeter contains a chamber and a filter section which is a rigid, porous fluoroplastic and through which moisture from the soil surrounding the lysimeter may pass into the chamber. The invention also includes a process for using the lysimeter to recover soil moisture in the lysimeter chamber.
