TLDR
In the ocean, nitrogen-rich microorganisms produce and recycle most organic matter in the water column, from which degraded particles rain onto the underlying sea floor and the buried organic matter joins the geological cycle, surfacing again millions of years later as kerogen uplifted in continental rocks as discussed by the authors.About:

Journal ArticleDOI
Persistence of soil organic matter as an ecosystem property
Michael W. I. Schmidt,Margaret S. Torn,Margaret S. Torn,Samuel Abiven,Thorsten Dittmar,Thorsten Dittmar,Georg Guggenberger,Ivan A. Janssens,Markus Kleber,Ingrid Kögel-Knabner,Johannes Lehmann,David A. C. Manning,Paolo Nannipieri,Daniel P. Rasse,Steve Weiner,Susan E. Trumbore +15 more
TL;DR: In this article, a new generation of experiments and soil carbon models were proposed to predict the SOM response to global warming, and they showed that molecular structure alone alone does not control SOM stability.

Stabilization of organic matter in temperate soils: mechanisms and their relevance under different soil conditions – a review
Margit von Lützow,Ingrid Kögel-Knabner,Klemens Ekschmitt,Egbert Matzner,Georg Guggenberger,Bernd Marschner,Heinz Flessa +6 more
TL;DR: In this article, a review of the mechanisms that are currently, but often contradictorily or inconsistently, considered to contribute to organic matter (OM) protection against decomposition in temperate soils is presented.
Journal ArticleDOI
The contentious nature of soil organic matter
Johannes Lehmann,Markus Kleber +1 more
TL;DR: It is argued that the available evidence does not support the formation of large-molecular-size and persistent ‘humic substances’ in soils, and instead soil organic matter is a continuum of progressively decomposing organic compounds.

Living in a fungal world: impact of fungi on soil bacterial niche development⋆
TL;DR: The emergence of fungi in terrestrial ecosystems must have had a strong impact on the evolution of terrestrial bacteria, and niche differentiation between soil bacteria and fungi involved in the decomposition of plant-derived organic matter is focused on.

Soil enzymes in a changing environment: Current knowledge and future directions
Richard G. Burns,Jared L. DeForest,Juergen Marxsen,Robert L. Sinsabaugh,Mary E. Stromberger,Matthew D. Wallenstein,Michael N. Weintraub,Annamaria Zoppini +7 more
TL;DR: The collective vision of the future of extracellular enzyme research is offered: one that will depend on imaginative thinking as well as technological advances, and be built upon synergies between diverse disciplines.

The nature and properties of soils
Nyle C. Brady,Ray R. Weil +1 more
TL;DR: The nature and properties of soils are studied to establish an understanding of the phytochemical properties of soil and how these properties change over time.

TL;DR: In this article, the effectiveness of various binding agents at different stages in the structural organization of aggregates is described and forms the basis of a model which illustrates the architecture of an aggregate.
