Influence of drainage systems on contamination water and soil

This study was aimed: at determining the concentration and leaching of nitrate, atrazine and heavy metals in drainage water and at determining the concentration of atrazine and heavy metals (Pb, Zn and Cd) in hydroameliorated soil. The study was conduced on reclamation test field, during of four years. The crop corn was grown. The weed protection was primextra. Nitrogen fertilization rate was 145 kg.ha-1 to 175 kg.ha-1 Based on the results, it may be concluded that concentrations of atrazine and NO3 – N in drainage waters exceeded the allowable values (0.1 μ g.dm-3) and (10 μ g.dm-3), while the concentrations of heavy metals were below from limited values, like and concentrations of atrazine and heavy metals in soil. Since the concentrations of atrazine and NO3 – N in drainage water exceeded the allowable values they need to be monitored and the actions need to be taken for their reduction.
