The classical methods,for the isolation of soil organic matter (SOM) components use aqueous base or neutral salt solutions, and combina- tions of aqueous,base and pyrophosphate. Organic solvents have been rarely used, largely because of difficulties in recovering solutes. This review provides the ...

Total soil organic matter content is a key attribute of soil quality since it has far-reaching effects on soil physical, chemical, and biological properties. However, changes in contents of organic carbon (C) and total nitrogen (N) occur only slowly and do not provide an adequate indication ...
