Dynamics and fate of natural and waste organic material in soils: the role of the soil organic matter (SOM) recalcitrance in SOM turnover
نویسندگان
چکیده
Previous studies suggested that micropore surface area (MiS) of bio-macromolecules of biomass constitutes an important factor that explains their preservation in soil, that is, the preservation against biological degradation. On the other hand it has been reported that biochemical catalysis are limited in theirs action by the very complex macroscopic and microscopic structure of cell walls that limit mass transportation. Results of this work indicated the structure (nanostructure) of the cell wall playing a main role in the preservation of the organic matter in soil. Total microporosity and pore dimension correlated with biomass degradation. On the other hand chemical composition determined by CPMAS 13NMR does not play a role in the definition of biomass recalcitrance.

Effect of Co-existing Heavy Metals and Natural Organic Matter on Sorption/Desorption of Polycyclic Aromatic Hydrocarbons in Soil: A Review
Polycyclic aromatic hydrocarbons (PAHs), abundant in mixed contaminant sites, often coexist with heavy metals. The fate and remediation of PAHs depend heavily on the sorption and desorption behavior of these contaminants. The sorption behavior can in turn be highly affected by certain soil components and properties, such as soil organic matter (SOM) and the presence of heavy metals. Through rev...

متن کاملThe Regulation by Phenolic Compounds of Soil Organic Matter Dynamics under a Changing Environment
Phenolics are the most abundant plant metabolites and are believed to decompose slowly in soils compared to other soil organic matter (SOM). Thus, they have often been considered as a slow carbon (C) pool in soil dynamics models. Here, however, we review changes in our concept about the turnover rate of phenolics and quantification of different types of phenolics in soils. Also, we synthesize c...
متن کاملThe background of non-crystalline materials and its role in soil organic matter turnover in subtropical volcanic soils
The high levels of soil organic matter (SOM), frequently found in soils with large content of noncrystalline minerals, are traditionally considered the result of strong organo-mineral interactions. Amorphous oxides are likely to provide active sites for SOM sequestration at the colloidal level. Considering that preservation of SOM is favoured by adsorption of humic colloids onto mineral surface...
متن کاملSorption, degradation and leaching of pesticides in soils amended with organic matter: A review
The use of pesticides in modern agriculture is unavoidable because they are required to control weeds. Pesticides are poisonous; hence, they are dangerous if misused. Understanding the fate of pesticides will be useful to use them safely. Therefore, contaminations of water and soil resources could be avoided. The fates of pesticides in soils are influenced by their sorption, decomposition and m...
