Predicting and mitigating changes in soil carbon (C) stocks under global change requires a
coherent understanding of the factors regulating soil organic matter (SOM) formation and …

The scientific understanding of the molecular structure of humic substances is critically
reviewed here. The traditional view that humic substances are polymers in soil is not …

Soil organic matter (SOM) and the carbon and nutrients therein drive fundamental
submicron-to global-scale biogeochemical processes and influence carbon-climate …

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 …

The soil organic matter (SOM) pool encompasses plant, animal, and microbial residues in all
stages of decay and a diversity of heterogeneous organic substances intimately associated …

Solid-state cross-polarisation/magic-angle-spinning 3 C nuclear magnetic resonance
(CP/MAS 13 C NMR) spectroscopy was used to characterise semi-quantitatively the organic …

The Handbook of Soil Science provides a resource rich in data that gives professional soil
scientists, agronomists, engineers, ecologists, biologists, naturalists, and their students a …

Solid-state 13C nuclear magnetic resonance (NMR) spectroscopy has become an important
tool for examining the chemical structure of natural organic materials and the chemical …

This review provides a comprehensive overview about nonextractable residue (NER)
formation and attempts to classify the various types. Xenobiotic NER derived from parent …

Our environment is essential for not only the quality, but also the persistence of life on Earth.
Three of the most pressing environmental issues facing modern society are climate change …
