“…Others (Guggenberger et al, 1995;Hu et al, 1995;Zech and Guggenberger, 1996;Zena et al, 1998) have observed that, for many tropical and temperate soils, carbohydrates in micro-aggregates and sand-sized particles were mainly due to decomposition of plant residues, whereas microbially derived sugars accounted for a larger proportion in clay-sized micro-aggregates. The higher carbohydrates concentration in the finer aggregates of the alley-cropped treatments at both Abakiliki and Umudike and of the poultry manure and rice mill waste treatments at Nsukka, may thus be related to an improved microbial activity because of the easily decomposable legume residues and fresh OM rather than accumulation of OC from plant residues.…”

“…It is a major indicator of soil quality since it is directly involved in the maintenance of soil fertility, prevention of erosion and desert encroachment and provision of suitable environment for biological activity (Zech and Guggenberger, 1996;Piccolo, 1996). According to Schlesinger (1997), organic matter is an important driving force in environmental global change as it acts as both a source and sink of atmospheric carbon.…”

“…This recalcitrant DOM is produced mainly through the solubilization of macromolecules (e.g., lignin and cellulose) in litter and is translocated down through the soil profile (Currie and Aber 1997). The differences in concentrations and fluxes of DOC between soil profiles under boreal and temperate forests demonstrate that the roles of DOM in the carbon (C) and N cycles vary depending on climate, vegetation types (broad-leaved vs. coniferous forests), and soil types (Zech and Guggenberger 1996, Michalzik et al 2001, Fujii et al 2009b. Fluxes of DOC and DON from the O horizons have been shown to vary from 6 to 30% and 1 to 53% of litterfall-C and -N, respectively (Michalzik et al 2001).…”

“…Most of the organic matter supplied to the organic (O) horizon of forest soils is mineralized, but a proportion is leached into the mineral horizons as dissolved organic matter (DOM) Likens 1988, Zech andGuggenberger 1996). The DOM transported into the mineral horizons may be mineralized, leached or adsorbed onto mineral surfaces (Kalbitz et al 2000).…”

“…The main SOM sources are: 1) allochthonous or external, such as surface runoff from uphill soils, or runoff seeping through leaves, twigs, trunks and litter (Zech and Guggenberger 1996), 2) autochthonous or generated sources in the soil by natural organic matter (NOM) decomposition, that it is later on released by microbial metabolites and root exudates, wich includes humic and fulvic acids (McDowell and Likens 1988, Guggenberger et al 1994, Guggenberger and Kaiser 2003, and 3) anthropogenic, made of synthetic organic substances, usually of industrial origin (Mostofa and Sakugawa 2009), often found in wastewater.…”
