URBAN FORESTS AND THE NEEDS OF VISITORS: A CASE STUDY OF KOŠUTNJAK PARK FOREST, SERBIA
Environmental Engineering and Management JournalVol. 16Nr. 10
Urban forests contribute to social, aesthetic and economic benefits within cities. In urban forest management, these aspects are often not incorporated, especially in the countries of South East Europe (e.g. Serbia), where the management of urban forests is still dominated by classical forestry aims (i.e. timber production). This paper analyzes the Košutnjak urban forest in Belgrade, with a special emphasis on the needs of its visitors and the importance of its use. We aim to raise awaren...

ANTIFUNGAL EFFECT OF NATURAL EXTRACTS ON ENVIRONMENTAL BIODETERIOGENS AFFECTING THE ARTIFACTS
Environmental Engineering and Management JournalVol. 16Nr. 11
The artifacts, as part of our cultural heritage, are exposed to fungal attack. Fungi can cause irreversible damage to the artifacts, resulting in economic, aesthetic and historical loss. The use of chemicals for the elimination of fungal biodeteriogens is currently a controversial subject, due to the potential toxic effect on human health and environment. The aim of this paper is to study the potential antifungal effect (on “environmental moulds”) of a series of extracts from nati...

MONITORING OF MOBILIZATION AND UPTAKE OF NUTRIENTS IN RESPONSE TO EDTA ADDITIONS TO A CONTAMINATED AGRICULTURAL SOIL
Environmental Engineering and Management JournalVol. 16Nr. 11
Mobilization of micro- and macronutrients and their uptake by Zea mays L. and Triticum aestivum L. in response to EDTA additions to risk metal contaminated agricultural soil was monitored over a three year period on the field scale. EDTA addition effectively increased the mobility of total water-soluble micronutrients (Cu, Fe, Mn) and macronutrients (Ca, Mg, P) in soil extracts. Mobilization was highest in the first year and decreased strongly over time. Elements with a high affinity for EDTA (C...

EFFECT OF ROCK PHOSPHATE AND SUPERPHOSPHATE APPLICATION ON MOBILITY OF ELEMENTS (Cd, Zn, Pb, As, Fe, Mn) IN CONTAMINATED SOILS
Environmental Engineering and Management JournalVol. 16Nr. 12
Weakly acidic Litavka and alkaline Malín soils are some of the most contaminated soils by multiple risk elements in the Czech Republic. The aim of this paper was to determine the effect of P sources (rock phosphate, superphosphate), each applied at three rates on the mobility of risk elements (Cd, Zn, Pb, As) and micronutrients (Fe, Mn) in soils and to compare their effectiveness with lime and dolomite tested in our previous study. In 7, 14, 28, and 42 days, we determined CaCl2-extractabl...
