Characteristics of methods of isolation of soil organic matter fractions and their use to assess the humus state of soils

In this work, the question related to the development and modification of the methodology for assessing the humus state of soils was considered. By the example of typical and ordinary chernozems of Krasnodar Krai redistribution of pools of labile carbon fractions in the process of agricultural land use was characterized. Based on the obtained data, the most informative indicator indices within the framework of the analyzed laboratory methods have been established. The theoretical justification was given and an estimation scale for the provision of soils of the North Caucasus region with permanganate-oxidizable organic matter fractions was proposed, and the significance of the information assessment of the humus state of soils was substantiated.
