Abstract: An apparatus for solarization of a volume of soil includes a support structure in the form of a frame having a first opening extending therethrough. The apparatus comprises a lid positionable over the frame, a plurality of walls extending under and away from the frame, and an assembly that redirects solar energy attached over the support structure. The lid and walls form a second opening. During operation the support structure is placed on a section of ground and adjusted for solar energy to be directed toward and through the lid. When placed on the ground, the frame, the lid, the walls and the adjoining ground form an enclosed volume that prevents thermal energy from escaping the enclosed volume while directing the solar energy into the volume via the second opening to heat underlying soil.
