An assessment of cadmium availability in cadmium-contaminated soils using isotope exchange kinetics
(Soil Science Society of America, 2004)
There has been much research conducted to find suitable methods for the determination of available Cd in soils. In recent years, an isotope exchange kinetics (IEK) technique has been tested to describe the kinetic transfer ...
Kinetics of cadmium and cobalt desorption from iron and manganese oxides
(Soil Science Society of America, 1995)
Oxides of Fe and Mn in soils are capable of sorbing large amounts of trace metal ions and can therefore be important in controlling trace metal concentrations in soil solution, and hence trace metal bioavailability in ...
Cadmium and cobalt desorption kinetics from soil clays: effect of sorption period
(Soil Science Society of America, 1998)
Soil solution metal concentrations and hence metal bioavailability are controlled by sorption-desorption reactions at the surfaces of soil colloids. Compared with the numerous studies on sorption of metals by soils, there ...
Desorption of copper from some New Zealand soils
(Soil Science Society of America, 1993)
Availability of soil Cu to plants is dependent on the desorption into the soil solution of Cu from the surfaces of soil colloidal materials. Although there have been many studies of Cu sorption by soils, however, few have ...
Application of capillary electrophoresis to anion speciation in soil water extracts: II. Arsenic
(Soil Science Society of America, 2000)
A method has been developed for the speciation of arsenic (AsO₂⁻, AsO₄³⁻, and dimethylarsinic [DMA]) in natural soil solutions from contaminated sites in Australia. The separation of these anions was achieved by capillary ...
Critical evaluation of methods for determining total organic phosphorus in tropical soils
(Soil Science Society of America, 1990)
The determination of total organic phosphorus (TOP) in soils presents several methodological problems, particularly on strongly weathered and tropical soils. We reviewed the application of several methods for TOP determination ...
Influence of organic and mineral amendments on microbial soil properties and processes
(Elsevier, 2007-01)
Microbial diversity in soils is considered important for maintaining sustainability of agricultural production systems. However, the links between microbial diversity and ecosystem processes are not well understood. This ...
Effects of past and current crop management on soil microbial biomass and activity
(Springer Berlin / Heidelberg, 2007-06)
Because soil biota is influenced by a number of factors, including land use and management techniques, changing management practices could have significant effects on the soil microbial properties and processes. An experiment ...
Small-scale spatial variability of selected soil biological properties
(Elsevier, 2004-04)
A strategy for sampling soil from intact monolith lysimeters was established based on measurements of spatial heterogeneity within the lysimeter area. This was part of an ongoing study to determine relationships between ...
Phosphorus-31 nuclear magnetic resonance spectral assignments of phosphorus compounds in soil NaOH–EDTA extracts
(Soil Science Society of America, 2003)
Soil P composition can be conveniently determined in alkaline extracts using solution ³¹P nuclear magnetic resonance (NMR) spectroscopy, but spectral assignments are based on fragmentary literature reports of model compounds ...
