AB  - 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.

AB  - Mikroorganizmi su indikatori plodnosti zemljišta, ali i procesa njegove degradacije. Povećane količine teških metala u zemljištu ili u zemljišnom rastvoru mogu imati toksičan efekat na rast i razviće svih sistematskih i fizioloških grupa mikroorganizama u zemljištu.

Ukupan sadržaj Pb i Cru ispitivanim uzorcima ackarbonatnog fluvisola bio je iznad maksimalno dozvoljene količine, što znači da svi uzorci analiziranih lokaliteta pripadaju kategoriji kontaminiranog zemljišta. Konstatovana je značajna negativna korelaciona zavisnost između sadržaja olova i brojnosti amonifikatora. Ukupan broj mikroorganizama i aktivnost dehidrogenaze nisu se menjali pod uticajem povećanog sadržaja olova. Povećanjem sadrzaja hroma ukupan broj mikroorganizama i aktivnost dehidrogenaze su se smanjili, dok je broj amonifikatora bio u slaboj zavisnosti od sadržaja hroma.
AB  - Microorganisms are indicators of soil fertility and soil degradation. Increased amounts of heavy metals in soils and in the soil solution can have a toxic effect on the growth and development of systematic and physiological groups of microorganisms in the soil. The aim of this study was to determine the levels of lead and chromitim in fluvisol and its effect on the microbial activity in the soil under Trifolium pratense L. The total content of Pb and Cr in the samples of non-carbonate fluvisol was above the maximum allowable amount. which means that all samples analyzed sites belong to the category of contaminated soil. We found a significant negative correlation between lead content and the number of ammonitiors. The total number of microorganisms and dehydrogenase activity are not changed under the influence of increased lead content. Increasing chromium content of total microorganisms and dehydrogenase activity were decreased. while the number ammonifiers was in a weak dependence of the chromium content.
