EVALUATION OF THE QUALITY AND AVAILABILITY FOR IRRIGATION OF WATER FROM DIFFERENT SOURCES FROM SOUTHERN OLTENIA

Abstract

The researches were carried out under the conditions of 2019 and aimed at assessing the quality and availability for irrigation of groundwater and surface water from different sources located on the territory of Dabuleni Research Development Station for Plant Culture on Sands (Dabuleni RDSPCS). The results regarding the quality of the water showed different values according to the source and climatic conditions. The average values regarding the fixed mineral residue, pH, nitrate content and ammonium ions, determined in 9 working points, show that the analyzed sources cannot be used as drinking water, but can be used for irrigation of agricultural crops. The obtained results showed the following water quality indicators: mineral residue = 475 -1350 mg / dm³; pH = 7.05 - 8.43; nitrates = 10.23 - 28.08 mg / dm³, ammonium (NH4 +) = 1.73 - 8.82 mg/dm³
