Аннотация: Lignin that is the main matrix for the humus formation in Phaeozemsaffect greatly the transformation of their organic matter. The aim of this workwas a detailed characterisation of the lignin phenols composition and processesof their transformation in soils under the impact of soil plowing and drainageduring the last 30 years. The objects of investigation were Greyic PhaeozemsAlbic of south of the Russian Plain. The process of lignin determinationincluded the alkaline oxidation of a sample using copper oxide at 170 degreesunder the pressure in a nitrogen medium. The lignin phenols were divided by agas-luquid chromatograph. The proportions of lignin phenols in soils plougheddid not change under plowing. Drainage caused a deep transformation of ligninin soils and in the Fe-Mn nodules too. Lignin phenols are associated with thecoarse sand fraction.https://www.inderscience.com/info/ingeneral/forthcoming.php?jcode=ijargeDOI: 10.1504 / IJARGE.2020.10038091
