Positive Effect

The results of long-term research in experiments with crop rotations with different clover saturation are presented. It is shown that the cluster has a positive effect on the main indicators of vegetation of dark-gray forest soil. The introduction of two fields of perennial grasses into the six-field crop rotation significantly increases both the humus reserves and increases the productivity of arable land by 1.5–2 times compared to the crop rotation with a field of pure steam.

The analysis of the influence of species and the fullness of crop rotations on the productivity and efficiency of grain crops is given. It was revealed that the highest grain yield is observed in a 4-field grain-fallow crop rotation. The absence of a field of late spring crops (millet) in 2- and 3-field crop rotations reduces grain yield in comparison with 4- and 7-field crops, both on average over 28 years (1991-2018), and in wet and middle years. The bioenergy coefficient, judging by the costs and grain yield, was highest in a 2-field grain-fallow crop rotation (4.94), then in a 4-field rotation (4.60), then in decreasing order: 7-field (3.86) and 3- field (3.73). In calculating the costs of labor, fuel and energy per 1 ton of grain from arable land, the lowest indicators were obtained in 2-field and 4-field crop rotations. It has been established that in terms of production costs per hectare of arable land, the cost of production of 1 ton of grain, conditionally net income per hectare of arable land, the level of profitability, the leading place is occupied by a 2-field grain-fallow crop rotation. For example, the lowest production costs were noted in a 2-field grain-fallow crop rotation (7782.00 rubles), the highest - in a 7-field (13835.56 rubles). Hence, the lowest production cost of 1 ton of grain was obtained in a 2-field crop rotation, amounting to 5598.56 rubles, followed by a 4-field crop rotation with millet - 7392.66 rubles. And according to the level of profitability, as mentioned above, grain-fallow crop rotations are arranged in decreasing order with the advantage of a 2-field crop rotation in the following order: two-, four-, three- and seven-field - respectively 116.1; 53.2; 48.2 and 37.0 %.

The influence of rotation length and fullness of grain – fallow crop rotations with a different set of biological groups (biogroupps) - winter, early spring and late spring crops on the yield of grain crops and grain yield from 1 hectare (ha) of arable land in the chernozem steppe of the Saratov Right Bank is analyzed, based on calculations for 4-field - 8 rotations, starting from 1989 and ending in 2020 (2-field - 16 rotations, 3-field - 10). It was revealed that the highest grain yield of 1.63 tons (t) from 1 ha of arable land, both on average for 32 years (1989-2020), and (1.82 t / ha) in the first-fourth (1989-2004) and (1.44 t/ha) of the fifth-eighth rotations (2005-2020), is observed in the 4-field grain – fallow crop rotation with a set of biogroupps-winter, spring early and late. The absence of a field of spring late crop (millet) in the 2 - and 3-field crop rotations reduces the grain yield by 0.11 and 0.30 t/ha, respectively, in comparison with the 4-field, both on average for all years, and by 0.22 and 0.28 t/ha in the first-fourth and by 0.20 and 0.32 t/ha in the fifth-eighth rotations. During the transition from the first-fourth rotation to the fifth-eighth, a significant decrease in the yield of field crops was established: winter wheat in the 3-field crop rotation by 0.87 t/ha or 26.6 %, 2-field by 0.72 t/ha or 22.4% and 4-field by 0.70 t/ha or 21.8 %; millet by 0.43 t/ha or 16.3 %, spring hard by 0.40 t/ha or 29.6 %, soft by 0.35 t/ha or 24.6 %. In all three spring crops, the yield reduction is 2.0 times lower than that of winter wheat. In general, according to crop rotations, the yield of winter wheat, both for the entire period of research, and in the first-fourth, fifth-eighth rotation, fluctuated within limited of the error of the experiment.

Soil fertility in biologized crop rotations depends on the saturation of them with legumes and sideral crops, perennial grasses, the involvement of grain crops in the organic matter cycle. The crop rotation was studied: 1) four-field grain and steam: clean steam winter wheat chickpeas spring barley (control); 2) five-field grain and steam: occupied steam (clover green manure) winter wheat chickpeas spring barley mustard + clover; 3) seven-field grain and grass: occupied steam (green manure oats) winter wheat mustard chickpeas safflower dyeing spring barley sainfoin (hatcher field); 4) semi-field grass and grassland: occupied steam (phacelia green manure) winter wheat spring wheat chickpeas grain sorghum spring barley alfalfa (hatchery field). The highest balance of organic matter was ensured in a five-field grain-steam crop rotation with clover for green manure +1.92 t/ha, in this crop rotation the highest balance was observed for nitrogen +23.8 kg/ha and phosphorus +1.3 kg/ha, grain harvest from 1 ha of arable land 0.51 t/ha. The greatest balance of potassium was ensured in the seven-field grain and grass-crop rotation with facet on green manure +8.8 kg/ha. The highest humus balance was observed in a seven-field grain-grass-crop rotation with oats per green manure +0.12 t/ha.

Purpose. To determine the long-term effect of a complex of factors (anthropogenic and natural) on the productivity of sugar beet for a significant period and the level of pest reproduction. Study of short crop rotations. Methods. Field, laboratory, statistical. Results. The uneven distribution of precipitation during the sugar beet growing season has differently affected the efficiency of fertilizer systems and, as a consequence, the growth, development of plants and the yield of root crops. Yield of sugar beets at constant sowing on average for five years was dynamic, but its highest productivity, regardless of the fertilizer system, was in the first years of research, from 29.7 to 39.1 t/ha (on average for 1978–1982). Further cultivation in monoculture has led to yield reduction. The highest yield of sugar per hectare was also observed in the first five years, and varied in different fertilizer treatments from 4.67 to 6.22 t/ha. The lowest yield was in 1988–1992 and 1998–2002, 2.71 to 4.42 t/ha and 2.23 to 4.53 t/ha, respectively. Sugar beet yield in crop rotation was influenced by both forecrop and aftercrop. On average, during the years of research (2011–2019), the highest yield (43.0 t/ha) was obtained in the three-field crop rotation winter wheat — spring barley — sugar beet, while the lowest (41.8 t/ha) in the crop rotation sunflower — winter wheat — sugar beet, slightly higher in the four-field crop rotation soybean — winter wheat — sugar beet — corn (42.3 t/ha). The yield of sugar during continuous sowing, on average during the study period, was 3.5–5.1 t/ha, while in crop rotation it was 7.7–8.3 t/ha. According to the results of the survey of crops in the cotyledon phase, it was found that in unchanged sowing the density of common beet weevil (Bothynoderes punctiventris Germ) is quite high, 8.8 beetles/m2 (average for 2006–2008) and exceeds the harmfulness threshold (0.2–0.3 beetless/m2) several times. At this density, the damage to plant seedlings was significant. Conclusions. The yield of sugar beet is influenced by both natural and anthropogenic factors. Of the anthropogenic, in addition to fertilizers, it is important to adhere to scientifically sound crop rotation. Long-term stationary studies have shown that the cultivation of sugar beet in monoculture leads to a gradual and stable decrease in yield and, consequently, the yield of sugar per hectare. The use of mineral and organic fertilizers helps to increase yields, but not significantly. In addition to weather conditions, the yield of sugar beet in crop rotation is influenced by forecrop and aftercrop. In the studied crop rotations, the lowest yield was obtained in the crop rotation where the forecrop of beets was sunflower, and the largest yield was obtained with legumes. Observance of crop rotation affects the phytosanitary condition of sowing; therefore, in monoculture, the density of common beet weevil is much higher than threshold, which leads to additional costs.

The research aims to establish the eff ectiveness of granular chalk use produced by «Slavuta-Calcium» Ltd. under growing Poliska–90 winter wheat variety, changing the physicochemical properties of grey forest soil and the wheat productivity. It also aims to establish optimal dosis of «Slavuta-Calcium» granular chalk as the meliorant and mineral fertilizer for grey forest soil in the system of winter wheat fertilization. In the temporary fi eld studies, various doses of nutrients N60–90–120P30–45–60K60–90–120 combined with «Slavuta–Calcium» granular chalk in a dose of Ca230–460–690 kg/ha of the active substance were studied against the background of secondary plowing of rotation products – soybean biomass that averaged 2.34 t/ha. Granular chalk is a modern complex highly eff ective meliorant with the content of Ca – 37.7 and Mg – 0.2 %, the mass fraction of carbonates (CaCO3 + MgCO3) makes at least 95 %. It is characterized by a high level of solubility when interacting with moisture in soil. It has a form of white granules, the mass fraction of 4.0–6.0 mm in size granules makes not less than 90 % and the one of 1.0 mm in size makes less than 5 %. Reactivity – 97 %. The granular chalk is advisable to apply on acidic soils, as a highly concentrated calcium-magnesium fertilizer, with the former as the dominant fertilizer, to optimize the physicochemical properties of the soil, as well as the plant nutrition system, in particular, increasing the availability of an element for assimilation by plants and as long-term ameliorants. The eff ectiveness of the use of mineral fertilizers, in particular acidic nitrogen on highly and medium acidic soils, after chemical reclamation is increased by 30–50 %, and slightly acidic by 15–20 %. The increase in productivity of crops from the combined eff ects of nutrients and chalk granulated is usually higher than when separately applied. The eff ectiveness of the integrated action of these elements is manifested in the growth of plant productivity and the quality of the resulting products, as well as the optimization of physical chemical properties and soil buff ering in the long term. In order to optimize the physicochemical properties of the arable layer of gray forest soil and the productive nutrition of agricultural crops, winter wheat, in particular, biogenic elements should be used in doses N60-90-120P30-45- 60K60-90-120 with granulated chalk «Slavuta-Calcium» in doses of Ca230-460-690 kg/ha of active substance. Granulated chalk obtained as a result of industrial grinding of solid sedimentary carbonate rocks of natural origin, subsequently under the infl uence of the granulation process of the starting material contains Ca and Mg carbonates of at least 95 %, dense granules which facilitates convenient mechanized application, as well as chalk suitable for accurate metered application on the quest map. Key words: granular chalk, gray forest soil, chemical reclamation, crop productivity.

The use of nitrogen fertilizer is becoming a global problem; however continuous fertilization with nitrogen ensures large and constant harvests. An 8 year research (2006–2013) was conducted to evaluate the relationships between differently fertilized cultivated plant rotations. The research was conducted in Lipliunai (Lithuania) in the agroecosystem with nitrogen metabolism in fields with deeper carbonaceous soil, i.e. Endocalcari Endohypogleyic Cambisol (CMg-n-w-can). The research area covered three drained plots where crop rotation of differently fertilized cereals and perennial grasses was applied. Samples of soil, water and plants were investigated in the Chemical Analysis Laboratory of the Aleksandras Stulginskis University certified by the Environment Ministry of the Republic of Lithuania. The greatest productivity was found in a crop rotation with higher fertilization (N32-140). In crop rotation with lower fertilization (N24-90) productivity of cereals and perennial grasses (N0-80) was 11–35 % lower. The highest amount of mineral soil nitrogen was found in cereal crop rotation with higher fertilization. It was influenced by fertilization and crop productivity. The lowest Nmin and Ntotal concentrations in drainage water were found in grasses crop rotation. Crop rotations of differently fertilized cereals increased nitrogen concentration in drainage water. Nmin concentration in water depended on crop productivity, quantity of mineral soil nitrogen, fertilization, and nitrogen balance. The lowest nitrogen leaching was found in the crop rotation of grasses. Cereal crop rotation increased nitrogen leaching by 12–42 %. The usage of all crop rotations resulted in a negative nitrogen balance, which essentially depended on fertilization with nitrogen fertilizer.
