Patent ID: 7918627

Claim:
A method of treating soils, comprising: digging in the soil, to a given depth, several parallel trenches simultaneously each comprising a vertical furrow having a first width (L 1 ) and at the said given depth a horizontal furrow forming a tunnel having a second width (L 2 ) greater than the first, the horizontal furrows of the adjoining trenches being at least laterally adjacent, so that no dead space any longer exists between two adjoining trenches, depositing in said tunnels of all the horizontal furrows of the trenches a continuous stream of a liquid soil treatment, and stabilizing the soil by a homogeneous lateral distribution of the liquid soil treatment over the entire width of the horizontal furrows of the trenches, and by sinking of the soil that covers the stream of liquid soil treatment deposited in said tunnels of the horizontal furrows as the result of uniform plowing of this liquid soil treatment into the soil to be treated.
