To investigate the pollutants of the Kor River, water samples were collected during the rice-growing season in 2014. The first fertilizer was diammonium phosphate ((NH4)2HPO4). After first irrigation, supplemented with fertilizer usage, in the upper layers of soil causes an increase of NO3− concentrations to reach from 7.3 to 25.7 mgl-1 at the agricultural lands […]
Abstract The use of chemical fertilizers in agricultural sector leads to increase of nitrate concentrations in surface and groundwater. The present study determined the vast impacts of agriculture in Ardabil Plain in the northwest of Iran. The study surveyed and measured the amount of nitrate concentration in groundwater sources of 46 wells in the region. […]
Increasing population growth and civilization have caused great impacts on water quality. Among these, changes and excessive exploitation of land use have led to changes in the surface water quality to provide human needs. Therefore, the present study investigated the effects of land use on water quality using a spatial-statistical approach. To this end, the […]
