Physical properties and organic matter of Fluvisols under forest, grassland, and 100 years of conventional tillage
(Elsevier Science Bv, Amsterdam, 2013)
Although a large number of papers deal with effects of land-use change on soil properties, less attention is directed to the long-term effects of different land-use types on soil physical properties and organic matter in ...
Differences in symbiotic N2 fixation of alfalfa, medicago sativa L. cultivars and Sinorhizobium spp. strains in field conditions
(Romanian Biotechnological Letters, 2013)
In a two-year field trial, four alfalfa cultivars grown in all combinations with five strains of Sinorhizobium spp. were assessed for N2-fixing potential and compatibility of symbionts with the aim to co-select plant and ...
Influence of the chemical structure of poly(urea-urethane-siloxane)s on their morphological, surface and thermal properties
(Springer, New York, 2013)
Segmented poly(urethane-urea-siloxane)s (PUUS) were synthesized using 4,4'-methylenediphenyl diisocyanate (MDI) and ethylene diamine (ED) as the hard segment components and hydroxypropyl-terminated poly(dimethylsiloxane) ...
Trace element distribution in surface soils from a coal burning power production area: A case study from the largest power plant site in Serbia
(Elsevier Science Bv, Amsterdam, 2013)
The content of trace elements (As, Cd, Co, Cr, Cu, Hg, Mn, Ni, Pb and Zn) in surface soils in the area surrounding the largest coal-fired power plant in Serbia was determined to assess the contribution of emissions to ...
