Assessment of irrigation water quality at the territory of Vojvodina Province (Serbia)

Intensive crop cultivation systems require continuous monitoring of irrigation water quality as well the control physical and chemical soil properties. In view ongoing climate change a dramatic decrease in organic matter content, use low its adverse effects on soil, cultivated plants equipment must not be overlooked. The aim this paper was to evaluate general from different intake sources Vojvodina Province. presents results quality, collected during 2018 2019. research included 140 samples obtained three structures which collect wells, canals or reservoirs. Water assessed using following parameters: pH value, electrical conductivity (EC), total dissolved solids (TDS), ionic balance, sodium adsorption ratio (SAR) residual carbonate (RSC) value. diagram given by US Salinity Laboratory (USSL) FAO guidelines for interpretation used. Additionally, Nejgebauer classification water, developed specifically area Vojvodina, used third classification. Based mineralization values observed parameters were determined: average analyzed 7.89, ranged 7.14 9.01, while 0.10 3.50 dS/m, with an 0.85 dS/m. TDS analysis resulted wide range values, 112 mg/l 2,384 mg/l, 529,22 mg/l. SAR varied between 0.04-16.52 satisfactory 1.97. USSL produced similar RSC index <0, indicating that 57% investigating are without concerns use, whereas Nejgebauers 0-1.25 show over 75% suitable safe Since significantly affects plant productivity, it determines properties agricultural land, is high importance.
