In the fertilized plots, the content of the first and second fractions, as well as the total of all three fractions of humic acids, was higher than in the control group, while for fulvic acids, the dynamics showed the opposite trend. It was determined that the ratio of carbon in humic acids to total carbon in the fertilized plots ranged from 48.7% (by-products + manure + N32P32K32) to 50.6% (by-products + destructor + N32P32K32). In the crop rotation, this indicator was at the level of plots where only by-products were applied (control), which were 39.9% and 39.4%, respectively. Product Description popup.authors Oleksandr I.
