abstract = "Increased concentrations of heavy metals in some agricultural areas, primarily as a result of human
influence, threaten, among other things, the production of high-quality feed. Medicago sativa Lis
(alfalfa) is a perennial legume, which is regarded as the leading and most important forage crop for the
production of quality feed and used in fresh and canned condition as hay, haylage, silage, meal, pellets
and paste. The aim of this study was to determine the levels of mercury in soil and plants Medicago
sativa L.. to obtain information on safety of this nutrient. The examination was conducted in Hrtkovei,
in the Republic of Serbia. Examined soil belongs to the automorphic soils, humus-accumulative class,
type of chernozem, subtypes on loess and loess-like sediments and variety gleyic chernozem, with
profile Ajno-AC-C. Soil has a good physical and chemical properties and is suitable for the production
of alfalfa, if contamination with heavy metals would not be a limiting factor. The study involved eight
localities. Sampling of soil and plant material was carried out in May 2011., in the second production
year of alfalfa. Soil samples were taken in a disrupted state with agrochemical probe, at a depth of 0-30
cm. Mercury content was determined by cold vapor technique, using atomic absorption
spectrophotometer. The mercury content in soil samples of examined localities was below the 0.001
mg/kg, which was not exceeded maximum level of 2.0 mg/kg, according to the Regulations on
permitted amounts of hazardous and harmful substances in soil and water for irrigation and methods of
their analysis (Slu%beni glasnik RS, no. 23/1994). The content of mercury in Medicago sativa L. was
below 0.001 mg/kg, which is below the maximum permitted concentration, according to the
Regulations on the quality of the feed (Sluzbeni glasnik RS, no. 4/2010) is 0.1 mg/kg. On the basis of
these results it can be concluded that the examined samples of alfalfa are suitable for feeding animals
and do not threaten the food chain, as well as safe food production.",
