THE SPATIAL STRUCTURE OF GRAY FOREST SOIL BACTERIAL CENOSIS UNDER
DIFFERENT CONDITIONS OF USE
I. M. Malynovska
National Scientific Centre “Institute of Agriculture of the NAAS”, Chabany urban-type
settlement, Kyiv Region, Ukraine; е-mail: irina.malinovskaya.1960@mail.ru
Under the conditions of the stationary experiment (agrarian soils) and in the 22-year-old
deposit areas, the state of microbiocenoses of individual horizons of gray forest soil: humus-
accumulative (0-29 cm), illuvial (30-50 cm), transitional from illuvial horizon to solid (92-110 cm)
was studied. It was established that the quantity and physiological and biochemical activity of the
microorganisms of the studied ecological-trophic groups, the intensity and direction of the
mineralization processes are changing by the soil profile. The nature and extent of such changes
significantly depends on the way the soil is used.
Key words: bacterial cenoses, soil profile horizons, gray forest soil, ecological and trophic
groups, mineralization.
The efforts of microbiologists are traditionally aimed at studying the microbial cenosis of
the arable layer of soil, where the main stocks of organic matter are concentrated and
microbiological processes are more intensive. Usually poor organic matter lower horizons,
transitional between the humus layer and litter rocks are less studied. However, the population level
of microorganisms in the middle and lower horizons has both theoretical and practical interest.
L. M. Polianska et al. [1] on the example of four zonal soil types (gray forest, soddy-
podzolic, black and chestnut), it was established that the biomass of soil microorganisms is
relatively evenly distributed along the entire profile, rather than concentrated mainly in surface
horizons. For peat soils, data has also been obtained about the uniform distribution of microbial
biomass in many meter thickness [2].
Studies in which the microbial population of the soil profile was evaluated mainly related to
the determination of the number of microorganisms in individual groups [3, 4] or the total number
of bacterial cells and biomass of micromycetes [2, 5]. At the same time, the state of microbial
cenosis of separate horizons of the soil as integral structures was not studied, direction and intensity
of mineralization processes depending on the depth in the soil was not evaluated. The objective of
our study was to study the structure of bacterial cenosis of separate horizons of gray forest soils of
various uses.

Materials and methods. The study was carried out on gray forest soil (experimental farm
“Chabany” of Kyivo-Sviatoshynskyi district of the Region of Kyiv) in territorially close areas: 1 –
soil removed from agricultural use in 1987; 2-3 – agrarian soils of the stationary experiment, which
was laid in 1987. The studied variants with the system of soil cultivation traditional for the Forest-
Steppe zone, with integrated pest, disease and weed protection and agrochemical loading of various
intensity were studied: 2 – control, field crop rotation without the use of mineral and organic
fertilizers (extensive agrarian soil); 3 – field crop rotation with mineral fertilizers N96P108K112.5 at
the background of plowing a crop production by-product (intense agrarian soil).
The selection of soil samples was carried out from the horizons: He –humus-accumulative
(0-29 cm), Ih – illuvial (30-50 cm), Pi – transitional from the illuvial horizon to the solid (92-
110 cm) [6].
The number of microorganisms of certain ecological trophic groups was estimated by the
method of seeding a soil suspension on the appropriate digestive media [7]. The intensity of the
mineralization of nitrogen compounds was calculated according to E. N. Mishustin and
E. V. Runov [8], pedotrophicity coefficient – according to D. I. Nikitin and V. S. Nikitina [9],
humus mineralization process activity – by I. S. Demkina and B. N. Zolotariova [10].
The number of microorganism colonies was counted for 21 days, depending on the growth
rate and physiological characteristics of microorganisms of certain ecological trophic groups.
Probability of bacterial colonies formation (BCF) was determined by S. Ishikuri and T Hattori
method, described by P. A. Kozhevin et al. [11].
Results and discussion. According to Table 1, the soil of the horizon Ih contains much less
microorganisms than the horizon He. Thus, the number of ammonifiers is reduced by 24.0 times in
the Ih horizons of laylands, extensive agrarian soil – by 38.5 times, intensive agrarian soil – by 47.0
times. Similar indicators for pedotrophs are decreased by 28.6, 29.6 and 30.9 times, for
cellulosolytics – by 28.0, 22.4 and 22.3, for polysaccharide-synthesizing microorganisms - by 42.0,
23.7 and 5.5 times. respectively. The obtained data partly confirm the results of L. M. Polianska et
al. [1], which found that 20-40 cm layer of gray forest soil contains only 23 times less
microorganisms than in the horizon 0-20 cm. However, according to the same authors, with the
further deepening of the profile, the number of microorganisms almost does not change. Similar
data on the total number of microorganisms by the same authors were also obtained for typical
black soil. The results of our studies indicate a sharp decrease in the number of microorganisms
with deepening to the horizon Pi: ammonifiers in the layland soil – by 4,500 times, extensive
agrarian soil – by 9,800 times, intensive agrarian soil – by 9,700 times compared with He horizon.
Corresponding indices for polysaccharide-synthesizing bacteria are decreased by 19,100, 13,200
and 8,700 times, for micromycetes - by 385, 898 and 198 times. Perhaps this difference in the
results can be explained by the use of various methods for determining the number of
3
microorganisms, in particular, the method of direct counting of microorganisms by luminescent
microscopy, the disadvantage of which is the unreliability of differentiation of living and dead
cells, which gives an overestimated result of calculations.
Distribution of microorganisms by the profiles of the studied variants of use of gray forest
soil is significantly different. Thus, the layland soil of He horizon contains more microorganisms
than in the soil of extensive and intensive agrocenoses: polysaccharide-synthesizing – by 3.0 and
5.6 times, pedotrophs – by 3.1 and 2.3, oligonitrophils – by 3.3 and 3.2, denitrifiers – by 3.9 and
4.9, mineral phosphates mobilizers – by 2.8 and 3.5, organic phosphates mobilizers – by 5.1 and
3.8, streptomycetes – by 2.2 and 1.6 times, respectively. The number of ammonifiers in layland He
horizon exceeds the corresponding indicator of extensive agrocenosis by 79 %, and the soil of
intensive agrarian soil contains 10.5 % more ammonifiers than in the layland. A similar pattern is
observed with regard to immobilizers of mineral nitrogen, which are used in the metabolism of
ammonifiers products: the maximum amount of nitrogen immobilizers is contained in intensive
agrarian soil – by 14.5 % more than in the layland, and by 6.92 times more than in the extensive
agrarian soil (Table 1).
Comparison of indicators of the layland Ih horizon with the extensive and intensive agrarian
soils shows that the first contains more ammonifiers, pedotrophs, oligonitrophils, mineral nitrogen
immobilizers, denitrifiers, mineral phosphate mobilizers, organic phosphates mobilizers, nitrifies,
and streptomyces; layland Pi horizon contains more ammonifiers, pedotrophs, cellulolytics,
oligonitrophils, mineral nitrogen immobilizers, and micromycetes (Table 1). This testifies to the
existence of an effective substrate transport system down the profile to the lower horizons.
Therefore, the number of microorganisms in the layland soil is decreasing in the depth of the
profile not so intensively, as in agrarian soils. At the same time, there is a pattern: if the number of
microorganisms of a certain group in the upper layland horizon is smaller than in agrarian soils then
in the Pi horizon their number exceeds the corresponding index of agrarian soil.
In the layland soil the intensity of decrease in the number of cellulolytics is higher than the
indicators of extensive and intensive agrocenoses – by 28.0 and 22.4 times, respectively. Perhaps
this is due to the movement of soil in the process of plowing in agrocenoses, which contributes to
the penetration of cellulose-containing substrates into deeper layers of soil. However, layland Pi
horizon contains a larger number of cellulolytics than agrocenoses, and the rate of decline in
number in the depth of the profile is minimal (5,000 times), in agrocenoses the rate of decrease in
the number of cellulolytics is 13,500 and 23,100 times, respectively. Consequently, a sufficient
amount of soluble cellulose derivatives, used by cellulolytics for growth, is transported through the
capillary system of the layland soil to the depth of the profile. A similar pattern is observed
regarding the number of ammonifiers, pedotrophs, micromycetes and microorganisms of other
groups.

The data obtained by us on the more gradual decrease in the number of microorganisms
in the layland soil, as compared with the agrarian soils, does not coincide with the data of
T. H. Dobrovolska [4], according to which, a virgin (forest) soil is characterized by a sharp
decrease in the number and variety of microorganisms in the soil profile compared with
cultivated soils. According to our data, only the number of polysaccharide-synthesizing
microorganisms, organic phosphates mobilizers and autochthonous microbiota decreases in
depth of the profile from both agrocenoses (Table 1). Also, we had noted almost identical rates
of decrease in the number of all studied variants of the use of soil microorganisms such as
pedotrophs and oligonitrophils.
It is important to study the patterns of distribution of the micellar forms by the soil
profile: the maximum rates of decrease in the number of micromycetes are characteristic for the
profile of extensive agrocenosis, the minimum – for the intensive one. The rate of decrease in the
number of streptomyces depends not only on the way of using the soil, but also from the horizon.
It should also be taken into account the existence of spores and conidia in these groups of
microorganisms, which can be transported with capillary water and remain in anabiotic state for
an extended period, sprouting on digest media.
Nitrifiers are characterised by a sharp decrease in the number by layland profile (Table
1). As the microorganisms of this group belong to the strict aerobes, the marked feature
indicates, first of all, the lack of oxygen content in the lower horizons of the layland profile. This
is also confirmed by the maximum number of denitrifiers (anaerobes) in the layland Pi horizon.
The maximum amount of azotobacter is contained in the soil of extensive agrarian soil, in
the soil of intensive agrarian soil it is present in small amounts, and it is absent in the layland
soil. This pattern is confirmed by long-term observations. The study of the probability of
formation of colonies has shown that the physiological state of microorganisms depends both on
the horizon and on the way of using the soil (Table 2). Thus, the physiological and biochemical
activity of the ammonifiers of the upper horizon and the extensive agrarian soil is higher
compared with the activity of microorganisms of the Ih horizon, and vice versa is it lower in the
intensive agrarian soil. Cellulolytics in the layland soil and extensive agrarian soil are also more
active in Ih horizon, and in intensive agrarian soil, activity is the same in all studied horizons.
Layland pedotrophs are more active in He horizon, and pedotrophs of agrarian soils – in the
lower horizons. Thus, the physiological activity of microorganisms in the soil horizons depends
on many factors, in particular on the intensity of the transport of substrates and restorers in the
depths of the soil profile, the depth of penetration of the plant roots, the presence or absence of
mechanical cultivation of the upper layers of the soil. Therefore, the physiological and
7
biochemical activity of microorganisms with the deepening of the horizon of the existence of the
corresponding group of microorganisms does not correlate linearly.
The analysis of factors and indices that give an opportunity to characterize the direction
and intensity of microbiological processes shows that the degree of development of organic
matter of the soil in the depth of the profile of layland and intensive agrarian soil is reduced by
82.4 and 64.4 %, respectively, and vice versa in the depth of the profile of extensive agrarian soil
– increases by 38.6 % (Table 2). At the same time, a pedotrophicity coefficient is observed in the
illuvial-humus horizon. The oligotrophicity coefficient increases for all variants of the use of
gray forest soil in the illuvial-humus horizon, and then decreases in the Ri horizon.
The factor of immobilization and mineralization of nitrogen from He horizon to Ih
horizon gradually decreases in the depth of the profile of the layland and intensive agrarian soils.
With the transition to Ri horizon, the factor of mineralization of nitrogen sharply decreases: in
the layland 6.9 times, in intensive agrarian soil – 2.5 times compared with the Ih horizon. For
extensive agrarian soil, the low intensity of mineralization processes in He horizon is
characteristic.
The activity of mineralization of humus in the layland soil is minimal, in the extensive
agrarian soil it is maximal. For all three variants of soil use, there is a clear tendency to decrease
the activity of humus degradation down the profile. The agrochemical characteristics of the
layland soil indicate that the soil of He horizon contains humus of 1.43 %, Ih horizon – 0.41, and
Ri horizon – 0.18 % [6]. That is, the content of humus between the horizons decreases by 3.49
and 7.94 times. The number of autochthonous microorganisms decreases at a significantly higher
pace – by 68.8 and 113,200 times, respectively, while the physiological and biochemical activity
of these microorganisms in different horizons of the layland soil remains almost identical.
Consequently, the activity of decomposition of humus depends on many factors: the content of
humus, the concentration of easily recovered substrates and macroelements, presence of which
influences mineralization of humus substances, the availability of oxygen, the number of
autochthonous microorganisms, their physiological and biochemical activity, and other factors.
Consequently, according to the results of the study, the following features are established.
1. Humus-accumulative, illuvial horizons and horizon transitional from the illuvial to the
rock of the gray forest soil differ in the number and physiological and biochemical activity of the
microorganisms of the studied ecological trophic groups and depend on the way of using the soil.
Reduction of the number of microorganisms in the horizons of the layland compared with
agrarian soils is slower, perhaps due to the existence of a more effective system of transportation
of substrates and restorers down the profile on the layland soil.
8
2. The degree of absorption of the organic matter of the layland soil and the intensive
agrarian soil decreases from He horizon to Ri horizon by 82.4 and 64.4 %, respectively;
pedotrophicity coefficient increases in the depth of the profile of extensive agrarian soil in Ih
horizon and decreases in Ri horizon. The oligotrophicity factor increases in all variants of the use
of soil in the illuvially-humus horizon.
3. The intensity of mineralization of nitrogen compounds from He horizon to Ih horizon
gradually decreases in the depth of the profile of layland and intensive agrarian soil. Ri horizon
is characterized by a sharp decrease in the intensity of mineralization of nitrogen compounds: in
the layland – by 6.9 times, in intensive agrarian soil – by 2.5 times. For extensive agrarian soil, a
low level of mineralization processes intensity is typical for He horizon.
The previously obtained data on the minimum activity of humus mineralization in all the
horizons of the layland soil, the maximum – in the extensive agrarian soil, have been confirmed.
Regardless of the type of soil use, there is a clear tendency to decrease in the activity of humus
degradation down the profile.

ПРОСТРАНСТВЕННАЯ СТРУКТУРА
БАКТЕРИАЛЬНЫХ ЦЕНОЗОВ СЕРОЙ
ЛЕСНОЙ ПОЧВЫ ПРИ ЕЕ РАЗНЫХ
УСЛОВИЯХ ИСПОЛЬЗОВАНИИ

ННЦ «Институт земледелия НААН»,
п.г.т. Чабаны, Киевская обл.
В условиях стационарного опыта и на
участках залежи изучали состояние
микробиоценозов горизонтов серой лесной
почвы: гумусово-аккумулятивного (0–29см),
иллювиального (30–50см), переходного от
иллювиального горизонта до породы (92–
110 см). Установлено, что с глубиной по
профилю почвы изменяется численность и
физиолого-биохимическая активность
микроорганизмов исследованных эколого-
трофических групп, интенсивность и
направленность минерализационных
процессов. Характер и масштабы таких
изменений зависят от способа использования
почвы.
Ключевые слова: бактериальные ценозы,
горизонты почвенного профиля, серая лесная
почва, эколого-трофические группы,
минерализация

ВИКОРИСТАННЯ
І.М. Малиновська
ННЦ «Інститут землеробства НААН»,
с.м.т. Чабани, Київська обл.
В умовах стаціонарного досліду і на
перелогових ділянках досліджували стан
мікробіоценозів горизонтів сірого лісового
ґрунту: гумусно-акумулятивного (0–29см),
ілювіального (30–50см), перехідного від
ілювіального горизонту до породи (92–110 см).
Встановлено, що з глибиною у профілі ґрунту
змінюється чисельність і фізіолого-біохімічна
активність мікроорганізмів досліджених
еколого-трофічних груп, напруженість і
спрямованість мінералізаційних процесів.
Особливості і масштаби таких змін
залежать від способу використання ґрунту.
Ключові слова: бактеріальні ценози,
горизонти ґрунтового профілю, сірий лісовий
ґрунт, еколого-трофічні групи
мікроорганізмів, мінералізація.

It was established that the quantity and physiological and biochemical activity of the microorganisms of the studied ecological-trophic groups, the intensity and direction of the mineralization processes are changing by the soil profile. The nature and extent of such changes significantly depends on the way the soil is used. В умовах стаціонарного досліду і на перелогових ділянках досліджували стан мікробоценозів горизонтів сірого лісового ґрунту: гумусно-акумулятивного (0–29 см), ілювіального (30–50 см), перехідного від ілювіального горизонту до породи (92–110 см).
