The VS uses the following technical equipment:
Two ripper placed before the back labor body work the soil to a depth of 80 cm. Rise at the crescent and descend between the crescents. Thus to attain, in the stretch of land between the crescent, a collection bag which receives water from the crescents itself. This water is protected against evaporation and remains available to plant roots and groundwater. The two rippers are staggered so as to move any surface stone.
Weight of the plow: approx 2.000kg.
The costs are always to be established with the manufacturers.
In order to ensure continuity of work is needed to order spare parts for an amount equal to about 10% of the cost of the plow and 5% of the cost of the tractor.
This equipment set, including the integrative instrumentation, which varies according to the terrain worked to increase productivity and reduce the workload for the individual, constitute the UMSV (mechanized unit of the Vallerani System).
Older equipment (no longer in production)
Even with very low rainfall (200-500mm/anno) each micro-basin can collect up to 1000 liters of water, including runoff.
