Abstract
An apparatus and method for heat treating soil with or without sunlight, and more particularly to killing weed pests by pasteurizing a top soil thereby rendering the top soil particularly suitable for planting a fresh crop therein. In one embodiment a top soil heat treatment apparatus for pasteurizing a top soil is provided, the apparatus comprises a housing, a soil heater, and a first soil mover, such as a helical screw, adapted to contact a top soil with the heat source to provide pasteurized stop soil. A method is also provided to produce a pasteurized top soil suitable for planting a crop. The method comprises the step of transferring heat energy from a soil heater to a top soil in order to produce the pasteurized top soil. The pasteurized top soil has a substantially reduced capability of growing weeds and an enhanced capability of growing a crop planted therein.
