Abstract

Highlights: Impact of shelterbelts on the hexane-extractable lipid fraction in soils was shown. Similarities and differences of various classes of compounds were described. The major lipid components included n -alkanes, n -fatty acids and their esters. Anthropogenic contaminants were found in the all lipid fractions. Lipids of the 200-years old shelterbelt were richest in resistant compounds. Abstract: 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 1 Н and 13 С 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.
