The present disclosure provides a method and apparatus for sterilization of soil in the field by pressure comprising grinding up soil using a rototilling mechanism, creating a pulverized soil conveying the pulverized soil to a two-part holding container and, transferring the pulverized soil from a lower section of the two-part holder container to a middle container which is operably linked to a pressurization mechanism, thereby allowing for the pulverized soil to be treated and sterilized with high pressure in the middle container resulting in a treated soil. The treated soil is then transferred to a transfer container being configured to shape a growing bed to a desired configuration using the treated soil which is deposited there.
