Effect of pH on the sorption of uranium in soils

Journal of Environmental Radioactivity, 2001
This work was undertaken to study the influence of soil type and chemical composition on uranium sorption ratios (SR in 1 kg-1) in order to reduce the uncertainty associated with this parameter in risk assessment models. Thirteen soil samples were collected from three different locations in France under different geological conditions.

Soil pH Effect on Imazaquin Persistence in Soil

Weed Technology, 1996
Field studies were conducted to determine the effect of soil pH ranging from 5.1 to 7.1 on imazaquin persistence on a Grundy silty clay loam (2.8% OM). Imazaquin residues were equivalent at pH 5.5 or higher but persisted longer at pH 5.1. Corn shoot growth was not different at any soil pH. Corn grain yields in 1993 were lower in imazaquin-treated plots

Interactive effects of soil pH and substrate quality on microbial utilization

, 2020
Both soil pH and substrate quality exert a critical influence on the decomposition of organic substrates and the production of microbial biomass. However, it is elusive the interactive effects of soil pH and substrate quality on the microbial assembly ...

Environmental controls on soil pH in planted forest and its response to nitrogen deposition.

Environmental Research, 2019
BACKGROUND Soil pH is important for controlling many soil properties. The variation in soil pH can be associated with changes in climate, soil buffering system, nitrogen deposition, and plants.

The Effect of Soil pH on Nitrification in Coarse Sandy Soil

1996
The effect of soil pH on the nitrification at low temperatures was studied in a coarse sandy soil. Field incubations were carried out during two winter periods in a field trial with soil pH-values from 4.2 to 6.2. In the laboratory the effect of soil pH on N-mineralization and nitrification was measured after application of liquid pig manure and ...

Changes in soil pH due to the storage of soils

Soil Use and Management, 1998
Abstract. The pH of soil samples was remeasured after storage for 20 years in the laboratory. The pH decreases were minor in acid to neutral soils (‐0.3), but greater in alkaline soils (‐0.63). The pH differences were statistically significant only for alkaline soils.

Effect of Ph on The Bioavailability of Metals in Soils

1993
Heavy metals in soils may have a toxic effect on soil biota depending on the bioavailability of these metals. The fraction of a total metal content that is available for uptake by biota depends strongly on the chemical form in which the metals are present and where they are located in the soil system.

pH changes in the rhizosphere in relation to the pH-buffering of soils

Plant and Soil, 1987
pH values in the rhizosphere of peanut seedlings were measured with Sb micro electrodes in soils with a bulk pH between 3.9 and 7.7. Within 2–2.5 days the roots decreased soil pH to a minimum value which was linearly correlated with short term buffering capacity of the soils as determined by addition of HCl to soil suspensions.
