Effect of ferrolysis and organic matter accumulation on chromate adsorption characteristics of an Oxisol-derived paddy soil

Science of the Total Environment, 2020
How paddy cultivation influences the adsorption isotherms, envelopes, and the kinetics of hexavalent chromate (Cr(VI)) on Fe (hydro)oxide-rich paddy soil, as well as the mechanisms involved, remain largely unaddressed.

Paddy cultivation significantly alters the forms and contents of Fe oxides in an Oxisol and increases phosphate mobility

Soil and Tillage Research, 2018
To evaluate the effect of paddy cultivation on phosphorus environmental risk in an Oxisol–derived paddy soil, we examined phosphate (P) affinity on bulk soils and their different–size fractions with adsorption/desorption isotherms.

Adsorption and desorption of arsenic on an oxisol and its constituents

Water Research, 2004
The present work investigates the adsorption and mobility (desorption) of As(III) and As(V) on an oxisol, and its main mineral constituents, as part of a broader project aimed at selecting a soil liner to be used in tailings dams at a sulfidic gold ore plant.

Fate and distribution of 14C-atrazine in a tropical oxisol

Chemosphere, 2000
The herbicide atrazine is the most commonly detected pesticide in groundwater world-wide. A new microcosm test-system was used to determine the fate of 14C-atrazine in a Brazilian oxisol. 14C Ring-labelled atrazine was applied in a mixture with the commercial product Gesaprim 500 (Novartis) at a rate of 3 kg ha-1.

Effect of selenium and soil pH on cadmium phytoextraction by Urochloa decumbens grown in Oxisol.

Journal of Hazardous Materials, 2023
It has been speculated that selenium (Se) supply can affect cadmium (Cd) 'availability' and increase the Cd tolerance of plants used for phytoextraction, in a pH-dependent process.

Effect of compaction on the relationship between electrical resistivity and soil water content in Oxisol

, 2021
Geophysical methods that allow determination of soil electrical resistivity (ρ) make estimates of the space-time variation of soil water content (θ) viable, as well as of other important physical properties and soil structure. The aims of this study were
