“…The trends described above agree with those measured in a subsequent investigation on three different vermicomposting substrates from winery and distillery wastes which included a spent grape marc, a mixture of spent grape marc and lees cake, and a mixture of biosolid vinasse and vine shoots [64]. Other studies have also shown that vermicomposting of cow manure, sheep manure and exhausted olive pomace alone or mixed with sewage sludge (SS) induces the stabilization of several enzymes by binding to HS-like fractions [60,65].…”

“…Vermicomposting is generally more efficient than composting because earthworms feed on organic matter and create conditions that favor the colonization and degradation of partially-decomposed and fragmented organic material by aerobic microorganisms [22,60]. According to results obtained by several authors [60][61][62][63][64], a large net organic matter mineralization occurs during vermicomposting of organic wastes, because of the combined action of microorganisms and earthworms. As it occurs with composting, non-humified C and watersoluble C contents decrease, whereas the ratios total extractable C/ total organic C, HA-C/total organic C and HA-C/FA-C increase significantly.…”

Recycling the large amounts of organic wastes produced by agriculture, forestry, urban and industrial activities as soil, organic amendments are the most popular and efficient option for avoiding their dispersion in the environment and restoring, maintaining, and/or improving the content of soil organic matter. Chemical stability and biological maturity are two important factors for the successful use of organic wastes in agriculture with limited risk for the surrounding environment. Stabilization and maturation of raw organic wastes inherently imply the achievement of an extensive humification, that is, a wide conversion of easily degradable organic matter to refractory organic compounds that resemble native soil humic substances (HS). Soil HS are the most important components of soil organic matter responsible of several soil functions and processes. As a consequence, the amount and quality of HS‐like fractions in any organic amendment are believed to be of primary importance for its agronomic efficacy, environmental safety and economic value. The first part of this review focuses on the chemical and physico‐chemical changes occurring in the humic substances (HS) ‐like fractions of organic wastes of various nature and sources subjected to common treatment processes aimed at producing environmentally‐safe soil amendments with beneficial agronomic properties. The second part discusses the composition, structure, and chemical reactivity of the HS‐like components in organic amendments of various origins and nature, and their effects on native soil HS. The review concludes by highlighting the need for innovative research targeted mainly to achieve a better fundamental understanding of the molecular structure and reactivity of soil HS and HS‐like fractions in organic amendments, the mechanisms of HS formation and transformations in the natural environment and during the treatment processes of raw organic wastes, the interactions with metals and organic xenobiotics, and the direct physiological effects that HS may exert on plants.

“…Treatment processes such as composting or vermicomposting of raw organic wastes before application to soil lead to an extensive mineralization and partial humifi cation -that is, a wide conversion of easily degradable organic matter to refractory organic compounds that resemble native soil HS (Senesi, 1989 ;Senesi et al, 1996 ;Par é et al, 1998 ;Plaza et al, 2005aPlaza et al, , 2007Romero et al, 2007 ;. In principle, these treatments are accelerated versions of processes involved in the natural decomposition of organic debris in soil, achieved through the provision of the most favorable conditions for microbial activity.…”

“…During the treatment processes of organic materials aimed at producing highquality soil amendments, such as composting or vermicomposting, nonhumic components, such as cellulose, hemicellulose, and lignin, are degraded at different rates (S á nchez -Monedero et al, 1999 ;Romero et al, 2007 ). Water -soluble carbohydrates and phenols present within the NHC fraction of organic wastes are shown to play a very important role in organic matter degradation and humifi cation.…”

The aim of this work was to evaluate, through different analytical techniques, the evolution of some chemical and physicochemical properties of humic acid (HA)-like fraction extracted from an organic amendment, like rabbit manure, handle with composting followed by vermicomposting process, in comparison with soil HA, in order to reach an appropriate criterion to evaluate the maturity of an organic amendment.The raw material used was rabbit manure treated with composting followed by vermicomposting process. Soil and organic amendments were analyzed by chemical properties. The HA was extracted from the amendments samples and from an Entic Haplustol and analyzed the chemical and physicochemical characteristics by several analytical methods. Through these analytical techniques was possible to follow the evolution of the HAlike fraction during this stabilization-maturation process Through the composting followed by vermicomposting process the HA-like fraction are evolving toward more stable and complex macromolecule resembling native soil HA.
