In the north of the province of Santa Fe, especially in the forest wedge, Lower Submeridionals and Occidental Domo, there are more than three million head of cattle, where one of the main determinants of production is the irregular quality of groundwater For the watering of the hacienda. The fluctuation between dry and wet hydrological scenarios has a direct impact on production, where not only the free water table, which is the only available water, varies, but also the chemical quality of the water. In collaboration with the INA, the Government of Santa Fe and UNL Research Centers, INTA has developed research and transfer demonstration units in the fields of producers and experimental units of the Institution, designing and proposing different technologies that are consensual with the Producers in the management of rainwater supplemented with the underground. 3 water systems were implemented with different ways of using rainwater with groundwater, systematizing terrain to guarantee access and recharge of the free aquifer, with pumping mechanisms using renewable energy and with suction systems that do it in the part Surface of the aquifer, where all converge to a central mixing tank, to ensure that all animals take water with the same chemical quality, whatever the place of grazing. Since 2011 the variables of interest are monitored, where the premise is to have controlled the salinity of the water in the central mixing tank and that its variations throughout the year are gradual, since this maximizes livestock production. This is visualized in each of the three systems and, fundamentally in the central mixing tank, where the quantity, quality and opportunity during the year clearly show very positive results in the place studied.
