Identification of high cadmium-accumulating oilseed sunflower (Helianthus annuus) cultivars for phytoremediation of an Oxisol and an Inceptisol.

Ecotoxicology and Environmental Safety, 2020
Forty oilseed sunflower cultivars were screened in two soil types for phytoremediation of Cd coupled with maximum biomass yield and oil production. Several cultivars exhibited a significant difference in biomass and yield with enhanced uptake in shoots ...

Forms and balance of soil potassium from a long-term integrated crop-livestock system in a subtropical Oxisol

, 2020
The presence of animal grazing at different intensities in integrated crop livestock systems (ICLS) may affect the forms and the balance of K in the soil, especially after many years.

Evaluation of mercury phytoavailability in Oxisols

Environmental Science and Pollution Research, 2018
Mercury is a metal which is potentially toxic for the environment. Many factors control its retention in the soil, such as cation exchange capacity, pH, clay content, organic matter, and redox potential. It is important to know the phytotoxic effects of soil Hg to prevent environmental contamination and its entry into the food chain. Several analytical

Measurements and simulations of compaction effects on the least limiting water range of a no-till Oxisol

, 2020
No-till has many environmental advantages, but concerns are growing about vehicle-induced topsoil compaction limiting crop growth. We performed a wheeling experiment in a long-term no-till field on an Oxisol with sandy loam texture.

Oxisols and Ultisols

2015
Landscapes associated with Oxisols and Ultisols in Taiwan are stable and old, measured in hundred thousands of years, and the thickness can be up to 5 m. Plinthite may be present resulted from alternative wet and dry cycles by fluctuating water tables.

Effect of gypsum rates and lime with different reactivity on soil acidity and crop grain yields in a subtropical Oxisol under no-tillage

Soil & Tillage Research, 2019
The low solubility of lime (CaCO3) and the absence of soil disturbance in fields under no-tillage (NT) may diminish the effectiveness of surface liming to reduce exchangeable Al3+ (toxic to plants) and increase the base saturation in deep soil layers ...

Impact of a long-term crop-livestock system on the physical and hydraulic properties of an Oxisol

Soil & Tillage Research, 2019
Intensive cattle grazing and machine traffic may negatively affect soil structure, hydrologic processes and plant development in integrated crop-livestock systems. The pasture management is the critical factor controlling the efficiency of crop-livestock

Monovalent Ion Adsorption by an Oxisol

Soil Science Society of America Journal, 1987
Abstract An experimental method was developed to measure simultaneously the net proton surface charge density (σ H ) and surface excesses of metal ( n M ) and ligand ( n L

Mössbauer analysis of Brazilian Oxisols

Hyperfine Interactions, 1986
Three sets of Brazilian Oxisols have been analysed by Mossbauer spectroscopy at 290, 80 and 4.2 K. In most cases two resolved magnetic hyperfine patterns associated with aluminous goethite and hematite are resolved; their ratio is related to soil colour. Samples from a 3 m soil profile show that both oxides become decreasingly aluminium substituted and/

Chapter 9 Oxisols

1983
Publisher Summary The taxon of Oxisols contains intensively weathered soils, most of which occur in tropical or subtropical regions. As a rule, they are found on old land surfaces or in sediments that are derived from them, although they may also form in rapidly weathering materials.
