25. Consequently, the difference between the current C and the maximum SOC contents in this mineral fraction describes the soil C saturation deficit23,26. The contribution of stabilized C in the mineral fraction
aIn contaminated soils, several natural processes (biodegradation, oxidation, etc.) can induce degradation of organic pollutants. The aim of this work was to evaluate the impact of an abiotic low-temperature oxidation on a coking plant soil and its main organic constituents (coal, coke, coal tar...
In many parts of Africa, soil erosion is an important problem, which is evident from high sediment yields in tropical montane streams. Previous studies in Kenya pointed to a large contribution from catchments cultivated by smallholder farmers. This led t

Proteobacteria are the dominant plant colonists of most plant species investigated to date, along with Actinobac- teria, Bacteroidetes and Firmicutes [4]. Although Entero- bacteriaceae are not as common as other members of the Proteobacteria on plants, they are frequent constituents of plant ...
Asphalt means a dark brown to black cement-like material (solid, semisolid, or liquid in consistency) in which the predominating constituents are bitumens which occur in nature as such or which are obtained as residue in refining petroleum. PJM Interconnection, L.L.C. or "PJM" means the ...
These categories are briefly introduced in the next section and will be further described by the accompanying papers of this special issue on plant biostimulants in horticulture. 2.1. Humic and fulvic acids Humic substances (HS) are natural constituents of the soil organic matter, resulting from ...
