Abstract:
An apparatus for injecting gaseous material into soil, said apparatus adapted to be mounted on a frame adapted to travel along the ground, said apparatus comprising:a rotating furrow opening disc having an axis of rotation firstly inclined from a position perpendicular to the line of travel, such that a leading side of said disc moves soil to the leading side as it travels through the soil making a furrow, said axis of rotation secondly inclined from the horizontal such that said leading side is above a trailing side of said disc;means to introduce a gaseous material at a point adjacent to the bottom of the furrow formed by said disc;a wheel having a plurality of fingers radially extending from the axis of rotation of said wheel, said wheel adapted to roll along the ground on a path adjacent to the leading edge of said furrow;wherein the axis of rotation of said wheel is firstly inclined from a position perpendicular to the line of travel opposite the first inclination of said disc, and secondly inclined from the horizontal.
