The device is intended to break open a cultivated soil with a probe through which compressed air may be suddenly introduced into the soil by means of a fast closing valve (3), as well as a substrate by means of an injection valve (55). The fast closing valve (3) and the injection valve (55) are arranged in the upper part, respectively the lower part of an intermediate container (1) for the substrate. An injection pipe (12) with a compressed air outlet (15) is adjoined to the fast closing valve (3). The injection pipe (12) may be lifted up upon the opening of the fast closing valve (3) with a temporary delay of an injection valve seat (16) of the intermediate container (1) to release the injection valve (65). |
