[BOOK][B] Biogeochemistry
WH Schlesinger - 2005 - books.google.com
For the past 3.8 billion years, the geochemistry of the Earth's surface-its atmosphere, waters
and exposed crust-has been determined by the presence of biota. Photosynthetic organisms …

Microaggregates in soils
All soils harbor microaggregates, ie, compound soil structures smaller than 250 µm. These
microaggregates are composed of diverse mineral, organic and biotic materials that are …

Stabilization of organic matter in temperate soils: mechanisms and their relevance under different soil conditions–a review
Mechanisms for C stabilization in soils have received much interest recently due to their
relevance in the global C cycle. Here we review the mechanisms that are currently, but often …

Stabilization and destabilization of soil organic matter: mechanisms and controls
P Sollins, P Homann, BA Caldwell - Geoderma, 1996 - Elsevier
We present a conceptual model of the processes by which plant leaf and root litter is
transformed to soil organic C and CO2. Stabilization of a portion of the litter C yields material …
