SPECIAL ASPECTS OF MIGRATION OF WATER-SOLUBLE ORGANIC SUBSTANCE AND BIOGENIC ELEMENTS IN SOD-PODZOLIC SOIL DEPENDING ON FERTILIZATION SYSTEM AND MICROBIAL PREPARATIONS

Objective. To study special aspects of vertical migration of products of biological transformation of organic matter and biogenic elements in sod-podzolic soil under different modes of root nutrition of plants. Methods. Lysimetric experiment, agrochemical, mathematical and statistical. Results. Based on studies conducted in a long-term lysimetric experiment on sod-podzolic soil, periodically washed type of water regime was established, as a result of which 37 mm of moisture, 23 kg/ha of water-soluble humic substances, nitrogen (NO3–) 55 kg/ha, calcium oxide 91 kg/ha and magnesium oxide 26 kg/ha magnesium oxide is lost at the background without inoculation per crop rotation when using mineral fertilization system. The use of microbial preparations reduces the loss of these elements to 33 mm, 20 kg/ha, 52 kg/ha, 83 kg/ha and 25 kg/ha, respectively. It was established that the average infiltration of moisture from the layer 0–155 cm under crops of continuous sowing was 25–37 mm at the background without the use of microbial preparations and 22–33 mm at the background of inoculation. The mineral fertilizer system increased the losses of the soil solution by 9 mm and 7 mm versus the control variants, respective to the backgrounds. The lowest losses of productive moisture were reported in the variants where sidereal fertilizers were used. When replacing the mineral fertilization system with sidereal-mineral and organo-mineral fertilizers without compromising the yield of crop rotations, it is possible to reduce the loss of productive moisture by 1.5 times, reduce the loss of labile soil organic matter by 1.7–1.8 times, nitrate nitrogen by 8–10 %, calcium by 18–24 % and magnesium by 40–50 %. Due to the use of biopreparations, there is a reduction in losses of nitrate nitrogen by 5–18 %, magnesium — by 5–14 %, calcium — by 6–16 %. Conclusion. To reduce non-productive losses of moisture, water-soluble organic matter and biogenic element compounds, it is advisable to use green mass of green manures and microbial preparations at the background of the mineral system and fertilizer system NPK+manure. The use of microbial preparations helps to reduce the loss of nitrate nitrogen by 5–18 %, magnesium — by 5–14 %, calcium — by 6–16 %.

EFFECT TO CROP ROTATION AND FERTILIZATION SYSTEM IN YIELD AND TECHNOLOGICAL QUALITY IN SUGAR BEET (BETA VULGARIS L.)

he quality of sugar beet roots is estimated by the concentrations of K, Na and ?-amino nitrogen in cell fluid since sucrose content in the cell vacuole is the result of a balance of other active osmotic compounds (K and Na ions). Along with the increasing dose of organomineral fertilizers, sugar losses in molasses increase, the thin juice purity decreases, and, accordingly, white sugar yield decreases. Therefore, the optimal dose of fertilizers within the organomineral fertilization system on the typical leached chernozem (in the zone of sufficient soil moisture) was 40 t/ha of cattle manure + N90P110K130, which provides sugar yield of 6.37, 6.32, and 6.48 t/ha. Analysis of sugar yield per hectare under the conditions of insufficient soil moisture shows the importance of the right decision on short crop rotation. Thus, the highest sugar yield (5.73 t/ha) was observed in the grain – grass – hoed crop rotation against the background of 25 t/ha of cattle manure + N90P120K90. However, increased fertilizer doses, 25 t/ha of cattle manure + N135P180K135, causes a reduction in sugar yield and is not efficient in terms of additional input

Combined application of organomineral and mineral fertilizers in the fertilization system of winter wheat on the southern black soil of the Lower Don

The article presents an analysis of the determination of the effectiveness of mineral and organic fertilizers on the yield of winter wheat grain. The studies were carried out in 2017–2020 in the Rostov region on the southern chernozem. The object of research was the Doneko winter wheat variety. The predecessor is corn for grain. Ammonium nitrate, ANP fertilizer (16-16-16) and urea were used as mineral fertilizers, which were applied in the fertilization system of winter wheat and acted as a background option in the experimental scheme. ANP fertilizer (16-16-16) was introduced when sowing winter wheat, ammonium nitrate - scattered over thawed-frozen soil and carbamide in the heading phase by foliar method. Organomineral fertilizers were represented by the following types: Ruther, Leili 2000, Siamino Pro, Gumiful Pro, Soft Guard and Double Wine MKR (monocaliphosphate) produced by Biokepharm (Switzerland). The raw material for the production of organomineral fertilizers was the algae of the warm seas Laminaria. In the field experiment, the options for the joint application of foliar application and pre-sowing seed treatment with organomineral fertilizers were also studied. The control was the option without mineral fertilizers and the option with the background of the use of mineral fertilizers (farm fertilization system). It was found out that the use of organic fertilizers Ruter (0.5 or 0.25 l / t) and Leyli (0.25 l / t) for seed treatment before sowing, the use of Soft Guard (0.2 l / ha) and Gumiful Pro ( 0.2 l / ha) in the spring tillering phase and in the flag leaf phase against the background of sowing nitroammophoska at a dose of N32P32K32, random fertilizing on thawed-frozen soil with ammonium nitrate at a dose of N40 and the use of carbamide in the heading phase at a dose of N20 increased grain yield on average for 2018–2020 compared with the control (fertilization system of the farm) by 0.73 t / ha, or 23.0%. The maximum yield increase from the root-forming agent Ruther, used for pre-sowing seed treatment, reached 0.36 t / g, or 11.3%.
