内容 The soil desiccation method by the temperature within the scope from 100°to 110℃ by means of a thermostat is said to be the most standard one for the measurement of soil moisture content. The reason why the above method is generally considered to be most standard is chiefly based on the fact that the soil may be desiccated without making temperature rise over 110℃. The thermostat method is, however, quite inefficient for the propagation of heat to soil, because the air in the environment of soil is first heated, and then the heat is conducted to the soil by the air. The authors succeeded in devising such an equipment that soil is not heated over 110℃ by radiating the infra-red ray to the soil. By this method they tried to desiccate soil and obtained the following results: -1) The calorie per unit time the soil surface absorbed in case of the infra-red ray method was about twice as much as the case of the thermostat method. 2) The time required for the perfect desiccation of hygroscpic moisture of Kanto loam was about one half of the case of thermostat method.
