Abstract
The purpose of this paper is to identify the effects of applying fertilizer on water quality in a drainage basin. A lab-scale experimental catchment was set up. Then a nitrogen-base fertilizer was applied, followed by assessment of nitrates and nitrites concentrations in soil and groundwater. The values recorded for the nitrates and nitrites are far higher than the maximum allowable values of these compounds in the drinking water. In this context, the water quality problem is quite serious, the values of nitrates and nitrites being exceeded 8.4 times and 11.5 time respectively.
