Abstract
In the soil pasteurizing apparatus disclosed herein, soil to be treated is placed within elongate canisters which are then inserted in an enclosure in the form of a shallow box having a transparent window constituting one of the broad faces thereof. The canisters are spaced from each other and from the walls of the enclosure. Reflective means are provided for directing, onto the canisters, solar radiation which impinges in regions of the enclosure not actually occupied by the canisters. Thermally-induced circulation around the canisters further facilitates overall heating. The elongate configuration of the canisters permits even the interior portion of a usable volume of soil to be heated to pasteurizing temperatures using only the solar energy available in a convenient time interval, e.g. 3 hours.
