A sub-soil injection device (100) injects a soil additive, such as a pesticide, as included in a foam below the surface (102) of the soil (104). It concurrently distributes the foam into the soil (104) as the foam is injected resulting in an improved uniformity of distribution of soil additive in soil (104). The device comprises a tubular structure (106) which mounts into the soil (104) from a vehicle (108). It has first (106) and second (114) portions, leading (116) and trailing (118) portions, a lumen (120) along its length, lateral portions (122, 124) and a plurality of spaced apart ports (126). Each port (126) communicates the lumen (120) with the trailing portion (118). Foam flowing out the ports (126) moves backwardly. A shank structure (132) precedes and shields the leading portion (116) of the member (106). The shank structure (132) has a forward facing portion (134) adapted to cut through the soil (104). The shank structure (132) and member (106) are motivated by the vehicle (108) in a forward direction through the soil (104).

Un dispositif (100) d'injection dans le sous-sol injecte un additif dans le sol, tel qu'un pesticide, lequel est contenu dans une mousse injectée sous la surface (102) du sol (104). Il répartit simultanément la mousse dans le sol (104) à mesure que celle-ci est injectée, ce qui améliore l'uniformité de répartition de l'additif dans le sol (104). Le dispositif comprend une structure tubulaire (106) introduite dans le sol (104) à partir d'un véhicule (108). Il comporte des première (106) et seconde (114) parties, des parties avant (116) et arrière (118), une lumière (120) sur sa longueur, des parties latérales (122, 124) ainsi qu'une pluralité d'orifices (126) espacés. Chaque orifice (126) permet la communication entre la lumière (120) et la partie arrière (118). La mousse s'écoulant hors des orifices (126) se déplace vers l'arrière. Une structure (132) de tige précède et protège la partie avant (116) de l'élément (106). Ladite structure (132) de tige présente une partie frontale avant (134) adaptée pour fendre le sol (104). La structure (132) de tige ainsi que l'élément (106) sont mûs par le véhicule (108) vers l'avant dans le sol (104).
