“…Water quality problems have been reported in the provinces of Córdoba, Catamarca, Tucumán, and Mendoza. Vázquez et al (2006) carried out research on the sustainability of irrigated production systems at northwest/mideast sites in the Province of Buenos Aires. Furthermore, some results are found on the degradation of semi-arid rangelands in the Argentinean Pampa due to increasing grazing intensity (Noellemeyer et al, 2006), susceptibility to dispersion, effect on the soil water retention, and hydraulic properties of two irrigated soils, Typic Udipsament and Entic Hapludol, respectively, in the center-east and northwest of the Province of Buenos Aires, Argentina.…”
