ABSTRACT:
An apparatus and method for cultivating soil by forcing a burst of pressurized fluid into the soil. The apparatus is provided with a horizontal hollow shaft, rotatably mounted on a frame member, and having a plurality of hollow rods extending radially therefrom, and arranged in longitudinal rows. Each rod is tipped with a conically shaped soil piercing nozzle, and a burst of pressurized fluid is provided to the nozzles via a tank and valve arrangement. When the apparatus is pulled by a tractor, the longitudinal rows of rods are sequentially embedded in the soil under the force of the weight of the apparatus and a burst of pressurized fluid is vented through the embedded nozzles to break up the soil into small pieces. The fluid can be either air, water, or liquid fertilizer.
