A low cost hydraulically weighed lysimeter has been constructed from the material readily available in the market. The lysimeter which costs nearly four hundred rupees consists of a locally fabricated hydraulic load cell as the weighing device, a coconut oil drum as the inner tank filled with soil and a read out system with a provision to read weight changes in six lysimelers. The lysimeter is sensitive to 100 g (equivalent to 0.04 mm of water). The linear deflection in the water manometer recorded for the lysimeter is 20 ± 1 mm per kilogram.
