Patent ID: 7487731

Claim:
An apparatus for applying a liquid or a liquid-solid dispersion to soil when passed over said soil, comprising: a substantially linear elongate conduit having a distal and a proximal end, adapted at said distal end for releasable coupling to a supply hose for receiving said liquid or liquid-solid dispersion, and having at said proximal end an aperture; first valve means, situate proximate said proximal end of said elongate conduit, adapted to permit egress of a pig member via said aperture when said first valve means is opened; an outwardly-extending conduit, one end thereof in fluid communication with and fluidly coupled to said elongate conduit intermediate said proximal and distal end thereof; and at another end in fluid communication with a manifold member; a plurality of supply tubes, each in fluid communication at one end thereof with said manifold member and at another end thereof adapted to supply said liquid or liquid-solid dispersion to soil; and wherein said first valve means may be opened to permit passage of said pig member through said elongate conduit from said distal end to said proximal end and egress via said aperture, and wherein said first valve means may thereafter be closed to permit said liquid or liquid-solid dispersion to be supplied from said elongate conduit to said outwardly-extending conduit and thereafter to said manifold member for delivery to said soil when said apparatus is passed over said soil.
