- Comparative study of the composition of lipids extracted with n-hexane from soils under shelterbelts of different age and composition of plants and adjoining cultivated fields in agrolandscape has been carried out with the application of 1Н and 13С NMR spectroscopy. The lipid content correlates with the organic carbon content in soils and is the highest in the soil under the 200-years old shelterbelt. The data received indicate that hexane-extractable lipids from the soil under the 200-years old shelterbelt have undergone the most significant biochemical and chemical transformations (oxidation, hydrolysis, polymerization) with the accumulation of resistant compounds and destruction of esters of o-phthalic acid as anthropogenic contaminants compared to the lipids from the soil under the 14-years old shelterbelt and soils of adjoining arable fields.
