The invention concerns a device for diffusing in the soil volatile treating products. The invention is essentially characterised in that it comprises, on a mount frame (14), means (22) for pumping the products contained in storage means (20), feeding circuits wherein are arranged the pumping means (22) and which connect the storage means (20) to a manifold, and diffusing means (24) borne by at least a coulter (68) and connected to the outlet of the manifold to diffuse in the soil, when the coulter is introduced therein, a gas stream derived from the reaction of the treating products.
