Abstract

The design of a soil sample storage room that has been in operation since 1954 is described. The room provides a storage environment with a constant temperature of 55 °F and relative humidities of 90 – 97 percent. It is of wood frame construction, lined with copper sheeting, forming a watertight interior. The desired temperature and humidities are obtained by running water down the walls of the room and circulating it through a heat exchanger. The preparation of samples for storage and the effect of storage times on soils are discussed.
