BALMASEDA ESPINOSA, Carlos y GARCIA HIDALGO, Yoandris. Water quality for irrigation of the Naranjo river watershed, municipality Majibacoa, province Las Tunas. cultrop [online]. 2013, vol.34, n.4, pp. 68-73. ISSN 0258-5936.
The water quality is one of the studied elements when the watershed sustainability is valued. The objective of this research was to evaluate the water suitability for irrigation of the Naranjo river watershed. A sampling of six representative points of the watershed (three surfaces and three grounds) was carried out. The water quality was defined based on the guidelines of FAO and other specific indicators for irrigation. The ground waters are unsuitable for the irrigation of agricultural crops and the superficial ones have slight restrictions to moderate. Danger of alkalinization of soils product of the bicarbonate concentrations exists in the waters. On the other hand the sodium of the waters can pass to the soil solution and to substitute to the calcium and the magnesium causing the degradation of the soils.
