Effect of humic preparation and herbicide treatment on chernozem aggregate composition

The influence of the humic preparation and pesticides on dynamics soil carbohydrates structure ordinary chernozem during cultivation winter wheat chickpeas was studied. A positive trend in growth structural coefficient observed all variants. This dynamic confirmed statistically when a were used together: difference with control after treatment 1.54% (2019). decrease number water-resistant units from 87.4 to 56.6% entire field experiment. There significant increase aggregates by 1.9-5.4% are applied together preparation. aggregate water resistance criterion (API) 6.0% 17.2% variant variants 2017-2018 insignificantly expressed. sharp content 2019 is probably associated change culture crop rotation link chickpea. amount carbohydrate compounds varies 1.13 1.26% combined use
