This work presents the results of the study of changes of the potential contamination
of soybean agrophytocenosis in grain-row crop rotation by using different systems of farming
and typical black soil tillage. It was established that in the upper 0–5 cm layer of soil there are
on average 393–671 million pieces of weed seeds. which is 33.6–43.0% of the total number in
the layer of soil 0–20 cm. It was established that the use of periodical moldboard and superficial
basic soil tillage had no impact on reducing the potential contamination of typical black soil
compared to the variant of differentiated tillage. During subsurface plowing the total number
of seeds in the soil layer 0–20 cm increased by 13.5–25.8% compared to differentiated tillage.
In the variants of ecological and biological farming systems the number of weed seeds in the
layer 0–5 cm was 11.3–19.6% higher compared to the intensive farming system. Based
on monitoring of the species composition of the weed seeds bank it was established that
in the arable layer of the soil the largest share are annual dicotyledonous – 48–62%. annual
monocotyledonous – 30.2–44.6%. perennial – 0.9–3.3% of the total number. It was proved that
under the intensive system of farming the yield of soybean variety Silesia increased on average
from 10.2 to 147% compared to the ecological and biological system of farming. During
the biological system of farming soybean yield did not exceed 1.0–1.8 t/ha. Therefore.
the industrial and ecological system of farming had the greatest impact on reducing the potential
weediness of the soybean agrocenosis during the growing season. During the biological system
of farming crop yields decrease due to the accumulation of weed seeds in the topsoil and
formation of high actual weediness of the soybean agrocenosis.
