Abstract
Abstract Underground ditches with impermeable walls are created in deep sands of arid areas by means of a plough, adapted to dig a ditch. The walls of said ditch are sprayed with a material which makes it impermeable and deposits into said ditch irrigating conduits capable of supplying water or solutions of nutritious substances required for growing plants.

Independent Claim
149 words
A meliorating arrangement for reclaiming regions containing deep sands in arid areas on the principle of large area hydropony, comprising a meliorating plough having a front supporting frame part provided with supporting wheels, a rear frame part, said rear frame part pivotally linked to said front frame part, said rear frame part provided with a hydraulically controlled injection plough having a horizontally elongated plow blade extending transversely of the direction of travel of the plow, said blade being substantially trapezoidal in cross section adapted to form an opening in the sandy soil, means disposed along the rear of the plough blade for spraying a water impermeable substance into the thus created opening to form an impervious membrane thereon, an irrigation plough blade disposed behind rear part of said injection plough blade, said irrigatIon plough blade being provided with means for depositing a pliable irrigation pipe above said impervious membrane.
Claim 2
Dependent Claim

An arrangement as set forth in claim 1 said means for spraying substances to the walls of the opening comprising an exchangeable injection conduit with an outlet slot of adjustable width, making it possible to adjust the amount of supplied suspension and thus also the thickness of the impervious walls of the opening, a sliding plate with lowered rear part adapted to protect the outlet slot against contamination by the soil, said lower rear part reducing the height of falling of the sand or soil into the injected suspension after such sand or soil has been dug from the upper surfaces by the injection plough blade.
Claim 3
Dependent Claim
43 words
An arrangement as set forth in claim 1, said rear frame part supporting said injection plough blade and said irrigation plough blade being provided with means for adjusting the relative position of said rear frame part with respect to said front frame part.
Claim 4
Dependent Claim
46 words
An arrangement as set forth in claim 1, both said injection plough blade and said irrigation plough blade being supported pivotally by said rear frame part, and comprising means for simultaneously adjusting the position of both said plough blades with respect to the front frame part.
Claim 5
