Silicon (Si) is the second‐most abundant element in the earth's crust. In the pedosphere,
however, huge spans of Si contents occur mainly caused by Si redistribution in soil profiles …

Processes of soil organic matter (SOM) stabilization and the reverse, destabilization of SOM
resulting in subsequent release and mobilization of nutrients from SOM, remain largely …

This chapter, like Churchman (2000), seeks to bring readers up to date with information and
understanding about the alteration of minerals and the nature of their products in the context …

Amino acids, either in a free or polymeric state, represent a significant addition of N to most
ecosystems and therefore comprise a key pool in the soil nitrogen cycle. The ability of some …

Silicon (Si) released as H 4 SiO 4 by weathering of Si-containing solid phases is partly
recycled through vegetation before its land-to-rivers transfer. By accumulating in terrestrial …

The literature on the formation, structure and properties of allophane and imogolite is
reviewed, with particular emphasis on the seminal contributions by Colin Farmer. Allophane …

Recent reports of increasing iron (Fe) concentrations in freshwaters are of concern, given
the fundamental role of Fe in biogeochemical processes. Still, little is known about the …

A decade ago, tunnels inside mineral grains were found that were likely formed by hyphae
of ectomycorrhizal (EcM) fungi. This observation implied that EcM fungi can dissolve mineral …

Weatherable minerals in all podzol surface soils andshallow granitic rock under European
coniferousforests studied hitherto are criss-crossed bynumerous open, tubular pores, 3–10 …

Scenarios indicate that the air temperature will increase in high latitude regions in coming
decades, causing the snow covered period to shorten, the growing season to lengthen and …
