In this paper, nitrogen transformations were studied on 13 substrates from agro-industrial, agricultural or urban sources using a new method. This method was developed to determine the kinetics and balance of nitrogen transformation during anaerobic digestion with high inoculum-to-substrate ratio while avoiding instabilities with nutrients addition...
Increasing soil organic matter (SOM) is of primary importance for maintaining soil fertility and mitigating climate change. Leaving crop residues on top of soil is not always an efficient means of increasing SOM because (i) of the high mineralization of the crop residues, (ii) crop residues may increase the mineralization of existing SOM (priming e...

Deep soil carbon (>30 cm) is the primary pool of soil organic carbon (SOC). However, deep SOC is often not included in carbon inventories or management strategies, especially in North-Africa. The objective of the study was to determine the distribution and the main factors governing SOC storage along a representative toposequence in North-Eastern A...

L'initiative internationale "4 pour 1 000" a pour ambition de soutenir États et acteurs non gouvernementaux dans leurs efforts vers une meilleure gestion des stocks de carbone (C) des sols. Ces stocks dépendent des entrées et sorties de C dans les sols. Ils sont la consé¬quence de mécanismes interconnectés, agissant à une échelle spatiale fine, qui...
Mineralization processes in ultramafic laterites are partly controlled by fluid flow regimes in these porous and permeable systems. During weathering of ultramafic rocks, exothermic chemical reactions, such as hydration of olivine, may generate shallow subsurface (
The occurrence and diversity of biological soil crusts (BSC) a thin soil surface layer composed of phototrophic and heterotrophic microorganisms intimately associated with soil particles, are known as strong indicators of ecosystem health and sensitivity to soil surface disturbances and are key factors in the biochemical cycling of carbon and nitro...
