ARSENIC IN THE RHIZOSPHERE SOIL SOLUTION OF FERNS
International Journal of Phytoremediation, 2012The aim of this study was to explore the evidence of arsenic hyperaccumulation in plant rhizosphere solutions. Six common fern plants were selected and grown in three types of substrate: arsenic (As) -tailings, As-spiked soil, and soil-As-tailing composites.

Accumulation of phenanthrene and pyrene in rhizosphere soil
Chemosphere, 2000A study was conducted to determine PAH concentrations in the rhizosphere of plants grown in soil containing phenanthrene or pyrene. The rhizosphere of tall fescue and wheat grown in sterile soil contained 4-5-fold higher pyrene concentrations than unplanted soil.

Devising quantitative and qualitative methods for studying soil fungi is fraught with difficulties. Traditional isolation and enumeration techniques, like the soil dilution plate, and its modifications, which in essence involve adding soil, or a diluted suspension, to Petri dishes and covering with a suitable agar medium, are of very limited value in ...

RHIZOSPHERE MICROBIAL POPULATIONS IN CONTAMINATED SOILS
Water, Air, and Soil Pollution, 1997Rhizosphere microbial populations may increase bioremediation of soil contaminated with organic chemicals. A growth chamber study was conducted to evaluate rhizosphere microbial populations in contaminated and non-contaminated soil. Alfalfa (Medicago sativa L.) and alpine bluegrass (Poa alpina L.) were grown in soil containing a mixture of organic ...

Rhizosphere Engineering and Soil Sustainability
2021Soils are a vital part of agricultural production. Soil health plays a significant role in the best crop production. Nowadays, our lands are under immense pressure. This pressure may be in the form of climatic changes that affect crop productivity or may be due to population increment that forces our current food system to produce more food to meet ...

Mineralogy of Rhizospheric and Non-Rhizospheric Soils in Corn Fields
Clays and Clay Minerals, 1994Abstract Technical limitations have restricted investigations of rhizosphere mineralogy. Various analytical techniques were applied to assess root-mineral associations and dynamics in natural soils under corn production. Soil samples were collected between four and five weeks after planting and included rhizospheric and non ...

Rhizospheric Mobilization of Radiocesium in Soils
Environmental Science & Technology, 2000Though soil-plant transfer is the first step by which radiocesium enters the food chain, it has been scarcely studied in the rhizosphere. Forty-seven soil horizons from 17 pedons with widely varying properties were contaminated with carrier-free Cs-137(+) and placed into close contact with an active macroscopic rhizosphere of ryegrass for 4 days.

Summary A method for the micro-biological evaluation of soil fertility developed by H. P. Ritsch is described and investigated. The method aims to take into account the influence of microbial activity in the rhizosphere on plant growth. The enrichment of rhizosphere soil by root exudates is simulated by incubation of a soil with sugars (glucose ...

Rhizosphere Effect on Soil Algae
Nature, 1960VERY few studies of the effect of the rhizosphere on soil algae have been made in the past1, and in a recent review Starkey2 states that it is possible that algal populations may even be decreased in the root zone. This communication presents evidence for a well-marked rhizosphere effect on soil algae by the roots of cultivated tea plants nominally ...

Activity of enzymes in rhizosphere and non-rhizosphere soils amended with sludge
Soil Biology and Biochemistry, 1987A greenhouse study was conducted to determine the activity of enzymes in sludge-amended rhizosphere and non-rhizosphere soil. Sewage sludge was applied at the rate of 0, 40, 80 and 120t ha−1. The selected soil was Enon sandy loam (fine, mixed, thermic ultic Hapludalfs). Ransom soybean [Glycine max. (L.) Merr]. cultivar was used to stimulate rhizosphere
