ABSTRACT:
A process for treatment of turf by applying a turf treating material in a stream within a narrow slit formed in the turf below the turf growth zone. The slit is made to extend downwardly through the exposed leafy mat in a growth zone and at least part way through the thatch zone situated between the growth zone and a root/soil zone. The slit is formed by a coulter disk rolled in a forward direction of travel with a cutting edge aligned in relation to the forward path to minimize slit. A knife follows the disk to hold the slit open. Turf treating material is placed into the slit directly behind the knife. A skid is used, with the disk extending through slots formed therein to ride over the turf and prevent disruption of the leafy growth, thatch, roots and soil as the slit is being formed. The turf is allowed to close over the placed material thereby capturing the material at a selected depth for maximum effectiveness and to prevent runoff or evaporation of the material.
