Abstract

Apparatus for applying liquid-solid dispersions to soil. Valves are provided which permit cleaning. An elongate conduit, with an aperture at one end, and a first valve proximate such aperture may be opened to permit passage of a pig member. An upwardly extending conduit is 'T'ed' off the elongate conduit, and connects with a manifold and a plurality of supply tubes to direct the liquid-solid dispersions to the soil at various points along the frame of the applicator. A second valve may be provided on the upwardly extending conduit, which may be closed to prevent initial supply of the liquid-solid dispersion to the apparatus and instead flow to the aperture to prevent plugging during initial operation. The second valve, when closed, further serves as an anti-siphoning valve to prohibit further supply of liquid solid dispersion to the manifold. A method for cleaning such apparatus is further disclosed.
