The aim of this study was to examine the effects of soil type and forage crops on the content of manganese (Mn) in roughages, and forage quality regarding Mn content. The trial was carried out on chernozem and humogley under alfalfa and red clover. Samples for determination of Mn content in plant and total Mn content in soil were digested using the apparatus Milestone Ethos 1 and for Mn determination on ICP-OES Vista Pro-Axial Varian. Average total Mn content in soil of the tested sites was 473.1 mg/kg. Total Mn content in chernozem was higher than in humogley. Average Mn content in forage crops was 28.7 mg/kg. Dry matter Mn content was lower in crops grown on humogley. Mn content was significantly higher in red clover. Significant positive correlation was found between total Mn content in soil and Mn content in crops. Mn concentration in crops was below critical and toxic value. [ABSTRACT FROM AUTHOR]

Production of high-quality forage from alfalfa is influenced not only by the presence of nutrients, but also by the absence of harmful elements, such as heavy metals. Th e examination of the total heavy metals content (Ni, Cr, Pb and As) in gleyic chernozem soil of Srem loess terrace in Hrtkovci, under alfalfa (Medicago sativa L.) were carried out in 2011 in order to determine suitability for the production of safe forage. Th e total content of Pb, As and Cr was below the maximum permitted concentrations. Th e content of As, Cr and Ni was higher in the surface layer, unlike Pb, whose content was higher in the deeper layers of soil. A significant positive correlation was found between the total content of Ni, Cr and As. An increased concentration of Ni was found, which was above the maximum permitted concentration. It is necessary to further control its content and accessibility examination and extraction from plants, to prevent its entry into the food chain and provide safe food. [ABSTRACT FROM AUTHOR]
