The lysimeter consists of three 300mm diameter containers in which may be placed any soil type and a variety of crop types grown. Each container can then in turn be placed on a hydraulically mounted plate which is used to monitor system weight changes arising from evapotranspiration. Despite its simplicity, the apparatus has a high degree of sensitivity and may be used for student project work as well as for demonstration purposes.
