“…The current unfavourable food situation in the world due to the lack of food for many countries requires the leading producers of agricultural products, which includes Russia, to increase the production of food, especially from plant-growing raw materials, as much as possible, despite the negative projected global warming and critical droughts recurring from year to year in many regions and in particular in the Russian Federation [1][2][3]. In solving this problem, it is necessary to further expand the planting of highly productive crops, which include corn [4][5][6], improve its cultivation technologies using innovative technical and technological products, in particular the use of nitrogen fertilisers [7][8][9][10] preferably in liquid form [1,4,8] based on a carbamide-ammonia mixture -CAM (CAM-32, CAM+S). CAM is a unique highly effective liquid fertiliser with a prolonged effect due to the versatile effect of three forms of nitrogen on plants: nitrate, ammonium and amide ones, and only the amide form can be absorbed by the vegetative part of agricultural plants [1,6].…”

In the presented material of the Samara State Agrarian University and Don State Technical University, the results of research on improving technologies for cultivating grain corn on the drylands using nitrogen, mineral, liquid fertilisers based on a carbamide-ammonia mixture — CAM are considered: CAM-32, CAM+S produced by PJSC “Kuibyshev-Azot” (Togliatti, Samara region), introducing them with an innovative, agrochemical, modular, multifunctional complex “Tuman...” (LLC “Pegas-Agro” — Samara). With a significant demand of corn for moisture and nitrogen fertilisers, it is very difficult to get a high yield without irrigation on the drylands, and therefore various technologies for using more effective liquid fertilisers instead of solid ones are being investigated in a region with insufficient moisture supply: in the Samara region of the Volga region of the Russian Federation. CAM has specific properties to cause “burns” of corn leaves; corn is a promising, highly productive crop with a great need for a macronutrient-nitrogen in the composition of a carbamide-ammonia mixture, and therefore to minimise this disadvantage, special extension hoses should be applied to hose sprayers, but they also have a technological disadvantage: corn foliar feeding requires additional moisture in the form of intense summer precipitation for the delivery of fertilisers through the soil layer to the root system zone. Thanks to the appearance of the foreign “Duport” aggregate, this problem is solved by special injection working bodies when applying CAM in the soil internally. The successful import substitution of the Duport unit was carried out by LLC “Pegas-Agro” (Samara, Russia) as well as by many other enterprises, creating a special module: the multi-injector “Tuman” for injecting more effective CAM.

“…The basis for the yield of any agricultural crop is the technology of cultivation. The traditional technology involves the application of high doses of mineral fertilizers, chemical agents for pre-sowing protection of crops from diseases, experimental pests and elements of weeds [1][2][3][4][5][6][7][8]. All these measures increase and preserve yields of agricultural crops, but have side effects (contamination of soils, degradation of fertility) [9][10][11].…”

The purpose of the research was to study the effect of mineral fertilizers and biological product Bisolbi-fit as a modifier on the oat productivity. The studies were carried out on the experimental field of Ulyanovsk Research Institute of Agriculture, branch of Sam SC RAS. The soil was leached, heavy-clayey chernozem. The experiment was carried out in a 3-fold repetition by the method of split plots with a systematic arrangement of options. The total area of one plot was 145 m2 (5.8×25), the accounting area was 100 m2 (4×25). The experiment scheme was as follows: 1. Control; 2. Presowing seed treatment with BisolbiFit in a dose of 400–600 g/t; 3. N15P15K15 in a dose of 15 kg ai/ha; 4. N15P15K15m in a dose of 15 kg ai/ha; 5.½ N15P15K15m in a dose of 7.5 kg a.i./ha. The effectiveness of the fertilizers was assessed during the cultivation of crops for three backgrounds: 1) zero – without fertilization; 2) NH4NO3m – treated with BisolbiFit in the dose of 40 kg a.i./ha; 3) NH4NO3 – in a dose of 40 kg ai/ha. It was established that the use of the microbiological preparation based on the Bacillus subtilis strain Ch-13, intended both for inoculation of seeds and use as a biomodifier of mineral fertilizers, had a positive effect on the crop structure, yield and grain quality. The most effective option was the one with Azofoska applied in a dose of 15 kg and modified with BisolbiFit at the rate of 4 kg per one ton of fertilizers on all the backgrounds. The use of BisolbiFit both for the pre-sowing seed treatment and treatment of mineral granules, increased the NPK payback by the yield gain.

“…Критерием оценки эффективного плодородия служит обеспеченность почв доступными корневой системе элементов минерального питания -азота, фосфора, калия, которые считаются структурными элементами товарной массы культур. Недостаток этих минеральных элементов отрицательно сказывается на росте и развитии растений, что приводит к формированию невысокой урожайности [4,5].…”

A sample for half a century from 1970 to 2022 was considered, consisting of 7 components, in which the yield of spring wheat (Uf) performs the desired function, with the content of mobile phosphorus (R2O5), exchangeable potassium (K2O), and the proportion of acidic soils in the soil acting as arguments. arable layer (Dkp), the saturation of the arable layer with mineral (min.) and organic (org.) fertilizers and their sum (NPK) in kg/ha per dry matter within one municipal area. A statistically significant relationship was established between agrochemical properties (K2O, Dkp) and Uf with correlation coefficients (r) -0.48 and 0.39 at α = 0.05. Taking into account the pairwise correlation, a multiple correlation was calculated. For the entire sample (6 factors), r was 0.55, and for 2 factors - 0.53. Based on the parameters of correlation and regression analysis, an equation was developed to predict the yield of spring wheat based on agrochemical properties. This equation can be used to increase the efficiency of fertilizers, prevent soil degradation, optimize land use and increase profits in agriculture.With the maximum values of the actual yield of spring wheat - 0.86-4.59 t / ha, the estimated yield (urash) ranges from 1.44 (1990) to 2.77 (2017) t / ha. The absolute difference between the actual and projected (estimated) yield ranges from 0.02 to 1.97 t/ha. The relative deviation in % ranges from 1.03 (1985) to 161.6% (2010) with average values of 25.5%. Deviations of more than 50% occurred in 1981, 1988, 1998, 1999 and 2010, which were due to the influence of extreme dry years, which indicates the need to expand the sample by agro-climatic factors.
