Sažetak
In order to implement regulations from The Nitrate Directive in Croatian rural sector, sets of three lysimeters were installed at three agricultural plots in Varaždin County (April 2011). Since main aim is to estimate the impact of agricultural practice on soil and water pollution, each selected plot is characterized by different soil type and different type of production: from typical field crops to predominate vegetable production. The nitrates (NO3-N) are main agricultural groundwater pollutant and the only parameter which maximum allowed concentration (MAC) of 10 mg/l in aquifers is prescribed by The Nitrate Directive, hence its concentration is the most relevant analysis result. The average value of NO3-N in samples from Hrastovsko is 7, 5 mg/l, from Greda 36 mg/l and from Donja Voća 41 mg/l. According to the presented results, it can be concluded that NO3-N concentrations on two of three research locations are exceeding MAC. Stated conclusions suggest there is necessity for more precise and less abundant fertilization procedures in this area which can be adjusted according to regular soil and water nutrient content analysis.
