Summary A tension table may be constructed from a Perspex tray ⅝ in. thick, approximately 12 in. wide and 19 in. long with 21 drainage channels. With a filter paper membrane, which gives rapid transmission of water and can be readily changed when contaminated it may be used to equilibrate 3–4 kg of moist soil overnight at suctions up to 100 cm of water. Several small samples may be handled at once by using small filter‐paper trays.
