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 ...

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 ...

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 ...

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 ...

The modification of surface soil structure affects soil-water processes important in crop production and soil conservation. Effects of pretillage soil water content (PTSW) with multiple-pass tillage operations were determined ...

We investigated a relatively unexplored area of soil science: the fitting of parameterized models to particle-size distribution (a subject more thoroughly explored in sedimentology). Comparative fitting of different models ...
