The humin preparations influence on humus formation processes at straw decomposition in the soil

The humus formation processes at the decomposition of straw in ordinary chernozem were studied in the field and laboratory experiments. It is shown that the treatment of straw with humic preparations accelerates the processes of its mineralization and humification in the soil. The maximum intensity of the processes is noted at the first 5-7 months of experiment, as evidenced by increase in the content of mobile humus and decrease of the Cha: Cfa ratio.
