Abstrakt
The study aimed to measure the effect of tillage and
fertilizing systems in short crop rotation on the content, and сomposition
of humuse’s substances in soil’s type as typical chernozem of the zone
Forest-Steppe of Ukraine. The highest humus content was determined in
the variant with the application of 11.5 t ha–1 of organic fertilizers +
N27P38K45 kg ha–1. The humus content in the 0–10 cm layer against the
background of shallow tillage without a moldboard was 4.25%, with
moaldboard-subsurface tillage – 4.23%. These tillage systems have the
most favourable effect on the formation and humus matter (t ha–1). The
humus storage in the variant of shallow subsurface tillage was 41.4 t ha–1,
i.e. 1.3 t less than in differentiated tillage. The use of soil without
fertilizing led to significant humus losses and deterioration of the
compound of humus substances due to mineralization processes that
prevail over immobilization processes. When applying 11.5 t of organic
fertilizers and (N27P38K45) mineral fertilizers per hectare of crop rotation
area, the number of humic substances increased significantly and the
amount of fulvic acids in the top layer decreased. The ratio of HA (Humic
acids) to FA (Fulvic acids) is 2.48. The type of humus formation is humus-
fulvatic.
