Evaluación de la calidad química del suelo y aguas de riego en la UEB de cultivos protegidos La Siguaraya.

The work accomplished in the UEB Protected Cultivations “La Siguaraya” at Vazquez's town for the sake of evaluating the chemical quality of the ground and waters of irrigation in the protected cultivations, tomato, pepper, and cucumber. The quality of soils were evaluated with different techniques to evaluate the quality of the ground like the determination of the movable forms of phosphorous and potassium, of the pH anions, cations in water, salinity, the soluble partial salts and % of the soluble total salts. The chemical analyses of the water for irrigation demonstrated good values in pH, Conductivity Electric, anions (CO32-, HCO3- , Cl- , SO42-), cations(Ca2+, Mg2+, Na+, K+)  and all the aspects evaluated for salinity, account with the quality required for the watering use. The main problem establishes the handling of the ground where they detected high values in pH, Conductivity Electric K20, P2O5, in all the in-depth levels, proving to be significant of 0-10 cm, what the accumulation of salts provoked by the contribution of the irrigation and to a bad washed of salts in the ground.
