CONSERVING OF THE RESOURCES
The aim of the research was to compare the impact of organic and conventional farming systems on soil quality with respect to trace elements (TEs) status. A study was carried out on seven pilot farms located in Vojvodina, the northern part of Serbia. The investigation was conducted at three representative farms certified for organic production and four conventional farms, in total on 96 production fields with different history of farming practices. Total and plant-available concentrations of TEs (DTPA) were determined in soil samples taken from 0-30 cm depth. The concentration of TEs was measured by atomic absorption spectrometer (AAS).
