The idea had already been explored by the Canadians of I-Cubed, for the direct sowing of corn, but apparently without follow-up. AquaTill brings the subject back to the table, with American equipment tested in Australia by farmers from SANTFA. The principle: a very fine water jet, 2 or 3 tenths of a millimeter, and under very high pressure, 3,500 bars. he can slice a thick layer of plant debris for effortlessly let the disc or tooth pass tillage or sowing equipment. What upset the field of direct sowing.

Tested in Australia for direct seeding
This technique presented by AquaTill plays with soil conditions, dry or wet. It avoids the pinching phenomenon of the straw strands in the furrow. “Hair pinningIn Anglo-Saxon literature. All you need is a continuous, non-blown vegetal mat. Hence the presence of a pad or a wheel to give the water jet all its cutting efficiency. The water thus propelled into the soil also has a loosening effect. Finally it is possible to add a fertilizer or a phyto product for certain specific applications. For example the destruction of cotton regrowth.

AquaTill: a kit to be installed on existing equipment
In the documents published by AquaTill, the designers evoke a reasonable water consumption. Of the order of 120 to 450l / ha in a plot displaying 35 t / ha of plant residues. The implementation of the method uses a pump and a network of pipes and nozzles to be installed on existing equipment. When will a demonstration be in Europe?
