Comprehensive analysis of nitrates, sulphates and agrochemicals in leachates from an intensive agriculture area - A case study in Croatia
To better understand the impact of conventional agricultural practices on soil and water resources, two main objectives were established in this study: to measure nitrate (NO3-) and sulphate (SO42-) concentrations in lysimeters and drainpipes leachates in response to different nitrogen fertilization levels and soil amendments and to identify organic contaminants that could have originated from the long-term use of agrochemicals in historically intensive agricultural area in Croatia. During the two-year study period leachate samples were collected from lysimeters and drainpipes. Research results indicate NO3- content in both lysimeters and drainpipes increased with rising doses of N fertilizer. The highest concentration of SO42- was recorded in the treatment with added phosphogypsum, while in all other treatments the concentrations were low. Over 40% of the 287 target substances were detected at least once during the two-year study period but only two substances (IPC/propham and carbosulfan) were found to have concentrations above 0.5 μg/L. Additionally, three priority substances were continuously present in the leachate samples: atrazine, simazine and isoproturon.
