ABSTRACT:
An implement and process for implanting successive reservoirs, each including a "pit" and an adjacent "dam" in the ground surface along row crops for the purpose of retaining water and avoiding water runoff. The implement includes several spider wheels having radial blades spaced along a common shaft. The wheels are fixed to the shaft for common rotation. Blades of each spider wheel are angularly staggered from blades on other spider wheels of the same shaft. Weight of the spider wheels and shaft may therefore be carried by a minimum number of ground engaging blades to maximize soil penetration and minimize individual spider wheel weight. The present process involves formation of a pit in the soil surface and deposition of soil directly adjacent to the pit by rotating a radial blade surface about an axis while simultaneously moving the axis horizontally along the ground.
