The impact of agricultural soil erosion on the global carbon cycle
K. Van Oost,Timothy A. Quine,Gerard Govers,S. De Gryze,Johan Six,Jennifer W. Harden,J. C. Ritchie,Gregory W. McCarty,Goswin Heckrath,Costas Kosmas,Juan Vicente Giráldez,J. R. Marques da Silva,Roel Merckx +12 more
TL;DR: Using caesium-137 and carbon inventory measurements from a large-scale survey, consistent evidence is found for an erosion-induced sink of atmospheric carbon equivalent to approximately 26% of the carbon transported by erosion.
Influence of dry–wet cycles on the interrelationship between aggregate, particulate organic matter, and microbial community dynamics
Karolien Denef,Karolien Denef,Johan Six,Heleen Bossuyt,Heleen Bossuyt,Serita D. Frey,Edward T. Elliott,Roel Merckx,Keith Paustian +8 more
TL;DR: In this paper, the effects of DW cycles on aggregate stability, SOM dynamics, and fungal and bacterial populations in a Weld silt loam soil (Aridic Paleustoll) were evaluated.

Soil carbon storage controlled by interactions between geochemistry and climate
Sebastian Doetterl,Sebastian Doetterl,Antoine Stevens,Antoine Stevens,Johan Six,Roel Merckx,Kristof Van Oost,Manuel Casanova Pinto,Angélica Casanova-Katny,Cristina Muñoz,Mathieu Boudin,Erick Zagal Venegas,Pascal Boeckx +12 more
TL;DR: In this paper, the authors measured a range of soil and climate variables at 24 sites along a 4,000 km-long north-south transect of natural grassland and shrubland in Chile and the Antarctic Peninsula, which spans a broad range of climatic and geochemical conditions.

An Improved Colorimetric Method to Quantify Sugar Content of Plant Tissue
Jan Buysse,Roel Merckx +1 more
TL;DR: In this paper, a modification of the phenol-sulphuric acid method to determine the bulk of soluble or insoluble sugars in plant tissue is proposed, based on optimizing the phenolic concentration to obtain equal colour yields for glucose, fructose and sucrose.

Integrated soil fertility management: Operational definition and consequences for implementation and dissemination
Bernard Vanlauwe,André Bationo,Jonas N. Chianu,Ken E. Giller,Roel Merckx,U. Mokwunye,O. Ohiokpehai,Pieter Pypers,R Tabo,Keith D. Shepherd,Eric Smaling,PL Woomer,Nteranya Sanginga +12 more
TL;DR: In this paper, a robust and operational definition of Integrated Soil Fertility Management (ISFM) is developed, based on detailed knowledge of African farming systems, their inherent variability, and optimal use of nutrients.
