Although soil lipids are an important class of soil organic substances, which is involved in numerous soil processes, their origin and fate in soils is insufficiently known. Therefore, this study aimed at investigating the free lipid fraction in crop

Fatty acids, the most abundant class of soil lipids, indicate pedogenetic processes and soil management. However, their quantitative distribution in organo-mineral particle-size fractions is unknown. The concentrations of n-C 10:0 to n-C 34:0 fatty a

The chemical identity of organic nitrogen (N) containing compounds in soils is only partially known, because 20—35% of soil N can not be hydrolyzed and identified by wet-chemical methods. Therefore a new methodology for investigations of the extrac

Organic-mineral soil particles are formed and altered as a result of pedogenic processes and anthropogenic impacts on soils. They can be isolated from bulk soil samples by physical disaggregation followed by particle size and/or density fractionation
