The paper analyzes the results of an agrochemical survey for 2010-2019 of arable soils of the Ivnyansky district of the Belgorod region, located in the south-west of the forest-steppe zone of the Central Chernozem region (CDR). It was found that in the soil and climatic conditions of this area for the period from 2010-2014 to 2015-2019. a decrease in the doses of applied mineral fertilizers from 126.6 to 122.8 kg/ha and a simultaneous increase in the doses of organic fertilizers from 18.3 to 23.1 t/ha contributed to an increase in the yield of winter wheat by 28.3%, spring barley - by 22.7%, corn for grain - by 24.7%, sugar beet - by 34.8%, sunflower - by 26.6% and soybeans - by 15.2%. At the same time, the content of mobile forms of phosphorus in soils increased by 29, potassium - by 53, sulfur - by 0.20, copper - by 0.51, manganese - by 3.61, cobalt - by 0.007 mg/kg, organic matter - by 0.25%. As a result of the implementation of measures for chemical reclamation of acidic soils on an area of 29.6 thousand hectares, the proportion of acidic soils decreased from 80.0 to 56.2%.

The research was carried out to study the dynamics of fertility of arable soils in the southwestern part of the forest-steppe zone of the Central Chernozem region. The work was carried out according to the results of an agrochemical soil survey on the territory of Yakovlevsky district of Belgorod region. The soil cover was represented mainly by typical chernozems (57.7%) and leached (28.2%). Under these conditions, an increase in the average dose of organic fertilizers in the region from 6.5 t/ha in 2010–2014 up to 14.6 t/ha in 2015-2018 while maintaining the use of mineral fertilizers at the level of 82.9 kg a.i./ha, it became one of the main factors in the growth of the weighted average content of mobile forms of phosphorus in the soil from 101 to 167 mg/kg, potassium - from 120 to 183, sulfur - from 2.5 to 4.7, manganese - from 11.0 to 13.1, zinc - from 0.4 to 0.7 mg/kg. Bringing liming volumes in the region for 2015–2018 to 32.7 thousand hectares contributed to a decrease in the share of acidic soils from 84.7 in 2009 to 52.9% in 2018.Along with the improvement of the agrochemical parameters of arable soils, there was a significant increase in the yield of the main agricultural crops: winter wheat - from 3.38 to 4.55 t/ha, corn for grain - from 4.84 to 7.60 t/ha, sugar beet - from 36.8 to 56.4 t/ha

The Borisovsky district of the Belgorod region, located in the south-west of the forest-steppe zone of the Central Forest Region, was chosen for the study. The study covered an 11-year period, during which 3 cycles of agrochemical soil survey were conducted in the district - in 2010, 2016 and 2020. Analyzing the use of mineral and organic fertilizers, an increase in crop yield indicators was noted. Thus, an increase in the dose of organic fertilizers (up to 1.96 t/ha) and mineral fertilizers (up to 127.2 kg/ha) made it possible to obtain 5.13 t/ha of winter wheat, 4.19 t/ha of spring barley, 7.9 t/ha of corn for grain and 3.29 t/ha of sunflower seeds. In addition, the content of macro and microelements in the soil has changed. The active fight against soil acidity affected the content of available forms of phosphorus and zinc, the indicators of which decreased slightly.

Abstract In order to study the spatial distribution of biological and ecological patterns of grass ecosystems, we conducted an agrolandscape-ecological zoning of the territory of the Central Chernozem Region of Russia (CCR) on the basis of the author’s methodology. According to the zoning data, it is established that 75% of the territory of the CCR belongs to the forest-steppe zone. The Central Russian province of the forest-steppe zone covers 67% of the territory of the CCR. Yeletsky district occupies the eastern spurs of the Central Russian upland. The area of the district is 1929.7 thousand hectares. Most of the district (90%) is located in the Lipetsk region, 10% – in the Kursk region. In the past, the watersheds of the district were occupied by meadow steppes and partly oak forests. Currently, more than 80% of the district’s territory is occupied by agricultural land (arable land, pastures, hayfields). The structure of land is dominated by arable land-67% of the total area of the district, pastures occupy 11%, hayfields – 3%, forests – 7%, shrubs – 2%, under water and swamps – 1%, other land – 8%. The grass ecosystems of the meadow steppes preserved along the gullies and slopes are mainly used as natural grasslands (NG) and make up 79% of all NG of the Yelets District. The most common are the downed tipchak pastures on the slopes of different steepness. The yield of these pastures is 8–12 centners per hectare of dry eaten mass.

Aim. To establish the effect of different fertilization systems in short fi eld crop rotation on the change in the state of humus in the dark gray podzolic soils in Western Forest-Steppe of Ukraine. Methods. Field studies were carried out in a stationary experiment of the Department of Soil Science and Agricultural Chemistry of the L’viv National Agrarian University; determination of humus content – according to DSTU 4289:2004, and that of its labile forms – in accordance with DSTU 4732:2007, fraction-group composition – by Ponomare- va-Plotnikova’s method, according to the measurement procedure 31-497058-008-2002. Results. The use of organo-mineral fertilizer system in short fi eld crop rotation with the saturation of organic fertilizers of 15 t/ha of crop rotation contributes to the humus content increase by 0.7 % after the third rotation in 0–40 cm layer of dark gray podzolic soil, the increase in the share of stable forms of humic compounds up to 57–59 % and the increase in the ratio of R HA :R FA to 1.3–1.4. The study demonstrated very high dependence of amount of gross energy reserves in the humus on the R HA :R FA ratio. Conclusions. The combined application of organic fertili- zers in the form of manure, non-market of the crop (straw) and siderate, along with mineral fertilizers is re- commended in short fi eld crop rotations of Western Forest-Steppe of Ukraine toensure expanded reproduction of fertility of dark gray podzolic soil, improvement of its humus status, increase in gross energy reserves and the share of the stable forms and humic acids in the humus.

Addition of organic amendments is a commonly used practice to offset potential loss of soil organic matter from agricultural soils. The aim of the present study was to examine how long-term addition of organic matter affects the abundance of different soil biota across trophic levels and the role that the quality of the organic amendments plays. Here we used a 17-year-old fertilization experiment to investigate soil biota responses to four different organic fertilizers, compared with two mineral nitrogen fertilizers and no fertilization, where the organic fertilizers had similar carbon content but varied in their carbon to nitrogen ratios. We collected soil samples and measured a wide range of organisms belonging to different functional groups and trophic levels of the soil food web. Long-term addition of organic and mineral fertilizers had beneficial effects on the abundances of most soil organisms compared with unfertilized soil, but the responses differed between soil biota. The organic fertilizers generally enhanced bacteria and earthworms. Fungi and nematodes responded positively to certain mineral and organic fertilizers, indicating that multiple factors influenced by the fertilization may affect these heterogeneous groups. Springtails and mites were less affected by fertilization than the other groups, as they were present at relatively high abundances even in the unfertilized treatment. However, soil pH had a great influence on springtail abundance. In summary, the specific fertilizer was more important in determining the numerical and compositional responses of soil biota than whether it was mineral or organic. Overall, biennial organic amendments emerge as insufficient, by themselves, to promote soil organisms in the long run, and would need to be added annually or combined with other practices affecting soil quality, such as no or reduced tillage and other crop rotations, to have a beneficial effect.
