Trace metals, such as nickel (Ni), are often found associated with ferrihydrite (Fh) in soil and sediment have been shown to redistribute during Fe(II)-catalyzed transformation of Fh. Fh, however, is inhibited when natural organic matter (NOM) To explore whether NOM affects the behavior Ni we tracked distribution, Fe atom exchange, mineral Fh coprecipitated Suwannee River (SRNOM-Fh). As expecte...

this research was carried out for the purpose of urea fertilizer, organic matter and pgpr bacteria effects on yield and some growth indices on winter wheat (triticum aestivum c.v alvand). this research was carried out with factorial experiment on completely randomized design with 4 replication in greenhouse. treatments included bacteria 4 levels, without bacteri, a. brasilense, a. chroococum, i...

Juvenile rainbow trout (Oncorhynchus mykiss, 3 g) were exposed for 74 h in ion-poor (soft) water to a mixed-metal solution in the presence of 4, 6, and 10 mg C/L natural organic matter (NOM). The metals were 0.2 microM Pb, 0.1 microM Hg, 0.1 microM Cd, 1.3 microM Cu, 0.05 microM Ag, and 3.5 microM Co, and the natural organic matter was isolated by reverse osmosis from three sources in southern ...

The research aims to study the content of organic matter in typical chernozem, its distribution soil profile under herbaceous and wooden phytocenoses. Organic plays a key role functioning soils their stable performance ecological functions, including – protection function. This is particularly relevant growing urbanization. analysis includes 40 full-profile sections migration-segregated chernoz...
