Sandy soil often has low organic matter (SOM) content, cation exchange capacity (CEC), and water storage levels. requires specific management techniques to improve quality. The purpose of this study was evaluate chemical characteristics microbial activity sandy soil, as well the effects different rotation systems on crop yield in these environments. treatments consisted cultivation with cover c...

Both climate and plant species are hypothesized to influence soil organic carbon (SOC) quality, but accurate prediction of how SOC process rates respond to global change will require an improved understanding of how SOC quality varies with mean annual temperature (MAT) and forest type. We investigated SOC quality in paired hardwood and pine stands growing in coarse textured soils located along ...

the removal of copper (ii), zinc (ii), and chromium (iii) from wastewater by carrot residues(cr) was investigated to evaluate cation exchange capacity. the effects of solution ph and co- ions werestudied in batch experiments. adsorption equilibria were initially rapidly established, and then decreasedmarkedly after 10 min. column experiments were carried out in a glass column filled with cr toe...

Understanding the dynamics of potassium (K) and its availability is fundamental in efficient use as an important nutrient. The objectives present study were to compare standard K extraction methods for extractable kinetics adsorption on five different textured soils. soils analyzed physico-chemical properties, contents adsorption. had variable soluble (8-52mg kg-1), exchangeable (13-215mg fixed...

Herbicide carryover injury to rotational crops can vary in severity depending on the influence of soil properties herbicide bioavailability. Greenhouse bioassays were conducted with soybean, radish, and canola evaluate differences bioavailability three herbicides risk, atrazine, mesosulfuron-methyl, topramezone. Bioassays varying regional types nine treatment rates including a control. Plant vi...

Fluoride contamination has now become an emerging concern in agroecosystems. A diagnostic survey was conducted across the fluoride (F-) contaminated wetlands of Kuttanad, India with aim to examine influence edaphic factors on F- concentration soils. The soils (Inceptisols) predominantly sandy had a substantial percentage clay and soil characteristics such as bulk density (BD), moisture, tempera...

Abstract Biochar properties are highly dependent on the feedstock type and operational conditions during thermochemical processing, in particular slow pyrolysis. To clarify this aspect, nine biochars were produced by pyrolyzing a macro TGA at 400, 550, 650 °C three different decorticated chopped biomasses. The studied biomasses representative of conifer (black pine) deciduous (poplar willow) wo...

The bare lands formed after volcanic eruptions provide an excellent opportunity to study the interactions between vegetation succession and soil formation. To explore changes in physicochemical properties processes relationship them, of different ash accumulation on Miyake-jima Island were studied at stages. results showed that bulk density gradually decreased porosity, water content (SWC), pH,...
