Dear fellows, does any of you know about a comprehensive review on the effects of LC/LU on soil particle size distribution (aka texture)?

I have noticed that this is a disputable matter: are soil texture a persistent property of soils or can Land Use and Land Cover modify it?

Dear fellows, how can I express the concentration of a "metallorganic" ionic complex in terms of cmolc.L^-1?

I'd like to express the concentration of silver thiourea in aqueous solution [Ag(TU)n]+1 in terms of cmolc.L-1. The protocols for soil CTC using AgTU consider the mass of Ag for calculations and...

Dear fellows, Do you know any comprehensive review about soil weathering indexes?

Weathering indexes are useful to estimate the intensity or the duration of a weathering process in geological materials as soils. But what are the pros and cons? What are the methodological issues...

Does any of you know about methods for evaluating the predictive and/or the descriptive power of mathematical models (e.g. sorption isotherms)?

With special concern to multimodel selection, linear regression and theoretic-informational approaches (e.g. AICc).

Does any of you know a comprehensive discussion on the concepts of "sorption" and "desorption", specifically for soil science?

Just read a lot of textbooks and papers on this subject. It seems that sorption is so much more favored than desorption within specialized literature. The very definition of these concepts is of...

Why do we still call Freundlich the van Bemmelen-Freundlich equation for sorption isotherms?

Just read the Derivation of the Freundlich equation by Sposito (1980). Sposito cites that van Bemmelen was the first to suggest the equation for solution-to-solid sorption of ions in trace amounts.
