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 ...

Addition of iron oxides, lime, clay minerals and other substances can be used to decrease the plant availability toxic heavy metals such as Pb, Zn, Cd. Extractability consequently concentrations may reduced in some cases by more than 50%. The assessment remediation processes is supported biomonitoring methods field with Plantago lanceolata greenhouse barley test experiments, combination extract...

cated that Mo adsorption on calcium carbonate was low, reanalysis of their data indicated that adsorption on The constant capacitance model, a chemical surface complexation this CaCO3 at pH 7.1 was comparable in magnitude to model, was applied to Mo adsorption on 36 samples from 27 soil series selected for variation in soil properties. A general regression adsorption on illite at pH 7.0 and thr...

Low-temperature synthesis experiments on ferric oxide–water systems have resulted in disparate oxygen isotope fractionation–temperature (a-T) curves. In this study, recent ferric oxides, mostly goethites of Holocene age, were collected and analyzed from a variety of modern soil, stream, and marine environments, where formation temperature and the oxygen isotopic composition (dO) of the water fr...

Isoxaflutole is a preemergence herbicide that has been marketed as a substitute for atrazine. It is rapidly transformed to a more stable and soluble diketonitrile degradate (DKN) after field application and can further degrade to a benzoic acid degradate (BA) within soil. However, no previous research has been conducted to investigate DKN and BA sorption to metal oxide minerals. The primary obj...

Soil represents the principal environmental reservoir of many insect-pathogenic viruses. We compared the adsorption and infectivity of one occluded and two nonoccluded viruses, Helicoverpa armigera single nucleopolyhedrovirus (HaSNPV) (Baculoviridae), Cricket paralysis virus (CrPV) (Dicistroviridae), and Invertebrate iridescent virus 6 (IIV-6) (Iridoviridae), respectively, in mixtures with a se...

Chemical recalcitrance of biomolecules, physical protection by soil minerals and spatial inaccessibility to decomposer organisms are hypothesized to be primary controls on soil organic matter (SOM) turnover. Previous studies have observed increased sequestration of plant derived aliphatic compounds in experimentally warmed soils but did not identify the mechanisms for this enhanced preservation...

the relationship between some measure of soil P and runoff dissolved P (Gburek et al., 2000; Coale et al., The relationship between soil test P (STP) and dissolved reactive 2002; Vadas et al., 2002). However, recent research has P (DRP) in runoff has been shown to vary with soil type due to differences in soil properties. This study was conducted to determine shown that this relationship will v...

Clay mineral-containing nanocomposite hydrogels have been proven to have exceptional composition, properties, and applications, and consequently have attracted a significant amount of research effort over the past few years. The objective of this paper is to summarize and evaluate scientific advances in clay mineral-containing nanocomposite hydrogels in terms of their specific preparation, form...
