The population of nodulating R. leguminosarum bv. viciae in soil from a grass-covered valley area which had been used for bovine slurry deposition over a period of 5 years was analyzed. For these studies, a rapid and reproducible method based on enterobacterial repetitive intergenic consensus (ERIC)-PCR was applied to identify Rhizobium strains which had infected pea nodules. Soil samples were ...

Spectrophotometric determination of Cr (using 1.5–diphenyl carbazide), in aqueous, sediment and soil samples is reported. Different leaching reagents like 0.5M NaOH-0.28M Na2CO3 and 0.2 M H3PO4 were used for the isolation of Cr from sediment and soil samples. Determination of Cr by using 0.5M NaOH-0.28M Na2CO3 as leaching reagent followed by spectrophotometric measurements provided satisfied re...

ABSTRACT: Overall plant growth and microbial biomass can be effected by dust accumulation. The chloroform fumigation-extraction method was used to evaluating the effect of cement dust pollution emitted from Kurdistan cement factory on soil microbial biomass carbon. Chlorophyll content (a, b and total) of plants species was measured in different distance from cement factory. Mic...

Soil pollution and crop contamination by cadmium (Cd) and Arsenic (As) are widely-known and recognized as a global threat to sustainable life and the environment. Various factors contribute to soil pollution, including pollutants factor: sources of pollutants, pollutant pathways, the medium of pollution, and soil factor. Japanese agricultural soils in some region, have been heavily polluted wit...

Phytoremediation is a promising approach for cleaning up soils contaminated with heavy metals. Information is needed to understand growth response and uptake mechanisms of heavy metals by some plant species with exceptional capability in absorbing and superaccumulating metals from soils. Greenhouse study, field trial, and old mined area survey were conducted to evaluate growth response and Cu p...

The purpose of this study was to explore a possible relationship between the availability of metals in soil (Cd, Fe, Mn, Pb and Zn) and their concentrations in leaves of Vaccinium myrtillus L. as a species which has been reported to be a successful colonist of acid-and-heavy metal-contaminated soil. Analysis also concerned the antioxidant response of plants from three heavily polluted (immediat...

Saprolegniaceae are ubiquitous filamentous water molds. They occur as saprotrophs or parasitic on aquatic and terrestial plants and on aquatic animals, and a number of interesting fungi belonging to the Saprolegniaceae have been isolated from the soil. In the course of an investigation of the water molds in Argentina, an unusual species of Achlya was isolated once from soil collections. Brassic...

There have been identified three zones according to the degree of soil pollution with fluoride in the impact area of air emissions of the Kandalaksha Aluminium Smelter (Russia): zone of maximum pollution up to 2.5 km from the emission source with the content of fluoride from 5000 to 1200 mg/kg, zone of strong pollution up to 13 km from the plant with the content of fluoride between 1200-400 mg/...

Soil contamination by used lubricating oil from automobiles is a growing concern in many countries, especially in Asian and African continents. Phytoremediation of this polluted soil with non-edible plant like Jatropha curcas offers an environmental friendly and cost-effective method for remediating the polluted soil. In this study, phytoremediation of soil contaminated with 2.5 and 1% (w/w) wa...

Contents of total Hg and Hg fraction, organic matter, pH, grain size and chemical composition were measured to investigate the pollution characteristics and binding behavior of Hg in soils collected from the Chatian Hg mining deposit (CMD), southwestern China. The average concentration of Hg concentration in the CMD soils was 155 and 1,315 times higher than that in control soils and Chinese soi...
