Abstract. The article examines the relationship between the depletion of soils in micronutrients, the decrease in the nutritional value of agricultural products, and the increase in morbidity due to these factors.

The problem and purpose. Mineral degradation of soils in the modern agro-industrial complex often takes on a large-scale character. The intensification of production based on obtaining a "quick" and large harvest, the massive use of nitrogen and other macrofertilizers, and the lack of micronutrient application leads to nutrient depletion of soils, a decrease in the quality, quantity, and safety of agricultural products, which ultimately affects the health of consumers.

The purpose of the research was to identify the dependencies of the factors of soil micronutrient removal and non-replenishment on the nutrient composition of agricultural products and on consumer health.

Methodology. The research method was used, as well as methods of analysis, systematization, comparison, and generalization. Data was collected from open sources of the Russian Ministry of Agriculture, reports of the United Nations Food and Agriculture Organization, and scientific publications in the fields of agrochemistry and medical statistics.

Results. The influence of the elemental composition of soils and agricultural products on alimentary diseases has been revealed, which is caused, among other things, by elemental imbalance and the lack of replenishment of soil micronutrients in the modern system of agrochemistry and the agriculture.

Conclusion. In order to solve the identified problems, it is proposed to develop plans for optimizing the macro- and micro-mineral nutrition of soils, and to use new methods and tools for the production and application of macro- and microelements, such as advanced fertilizer mixing machines and lines, as well as spreaders for wide-component fertilizer mixtures with bio- and micro-additives.

Abstract. The article presents results on the nectar and seed productivity of Silphium perforatum, depending on the applied fertilizer rate.

Problem and purpose. Silphium perforatum has unique characteristics, including longevity, undemanding soil conditions, high yields starting from the second year of life, and nectar and seed productivity. Silphium is readily consumed by livestock. Silphium perforatum has been cultivated at the Federal Scientific Center for Beekeeping since 1973. Based on the above, the purpose of this study was to identify the relationship between mineral nutrition and the growth and development of Silphium perforatum.

Methodology. The experiment was conducted on a test plot at the Federal State Budgetary Scientific Institution "Federal Scientific Center of Beekeeping" in Rybnoye. The experimental design included a control and three options with different applied fertilizer rates. The research methodology was traditional. Results. Improving mineral nutrition through fertilizer application demonstrated the best result – N90 versus P60K90 – and therefore, this article presents the results of the study using this option. Soil nutrient levels increased by 13-16%, resulting in herbage yield of over 900 c/ha with high nectar and seed production.

Conclusion. A single application of mineral fertilizers at a dose of N90P90K90 contributed to accumulation of essential nutrients: available phosphorus up to 41.6 g and exchangeable potassium up to 10.5 g/100 g of soil. This improved the crop's growing conditions, resulting in shoots reaching a height of up to 220 cm and herbage yield of over 900 c/ha. Silphium heads were readily visited by bees and other insects. Nectar yield was 274.8 kg/ha, and seed productivity was 5.57 c/ha. Silphium perforifolia is an excellent forage crop due to its high content of digestible protein.

Abstract. The article presents results of a field experiment studying the effects of

mineral fertilizers with microelements, Aktiv Rost, Vigor Forte, and Stimax on the

yield and grain quality of spring wheat. The experiment took place in 2025 at

Avangard LLC in Ryazan District of Ryazan Region.

Problem and purpose. Wheat is a key element of the Russian Federation's food

security and agricultural exports. Therefore, Russian agricultural producers

annually face the challenge of creating optimal conditions for high grain yields of

both winter and spring wheat. It is also important to obtain high-quality grain that

meets modern requirements to increase the competitiveness of Russian grain.

Methodology. The experiment included four options: 1. Control (no fertilizer); 2.

Aktiv Rost, 1.0 l/ha; 3. Vigor Forte, 25 g/ha; 4. Stimax, 0.5 l/ha. The experiment was

replicated four times, with options assigned using the organized replication method.

The area of the experimental plots was 5.568 m², while the area of the sample plots

was 1.392 m². Harvesting was carried out using the continuous method. The results

were analyzed using analysis of variance.

Results. The spring wheat yield was 33.9 c/ha in the control option without

fertilizers. A significant increase at LSD05 of 3.08 c/ha was achieved in the

experimental options using Vigor Forte, 25 g/ha, and Stimax, 0.5 l/ha, amounting to

3.3 c/ha and 4.6 c/ha, respectively. Wheat grain quality was also higher in the

options with foliar application of mineral fertilizers containing microelements.

Conclusion. Research has shown that the use of Vigor Forte and Stimax for foliar

application of spring wheat during the tillering stage significantly increases grain

yield and quality.

Abstract. The article presents results of the biological activity of alluvial soil in the Ryazan region.

Problem and purpose. The main feature of alluvial soil is flooding and the introduction of alluvium during high water, which affects the microbiocenosis and nutrition of plants.

The purpose of the study was to study the effect of fertilizers on the micro- and mesobiocenosis of the alluvial saturated meadow soil of the Central floodplain of the Oka River. One of the research objectives was to assess the biological activity of the alluvial soil of the Central floodplain of the river. They were used for corn cultivation.

Methodology. The research began in 2024 in Ryazan district of Ryazan region on the territory of the Moskovskoye JSC enterprise. The soil was alluvial and saturated with an average level of fertility. Corn, which was cultivated for herbage and required fertile soil, was chosen as a crop under study. To obtain experimental data on the research topic, small-scale field experience and laboratory methods were used to study soil and corn plants.

Results. As a result of the conducted research, a significant effect of fertilizers on the biological activity of alluvial soil has been established. The decomposition rate of linen during the 3 months of exposure was highest in the NI5 – 60% and NII5- 75% variants, which is associated with an increase in the total number of microorganisms to 1.3-1.4×106. Similar changes were observed in the increase in the number of worms in the same variants to 57 and 61 individuals, with soil density decreasing by an average of 20%. The research results obtained have a preliminary assessment, and the experience continues.

Conclusion. The obtained results of biological activity studies show interim results after the first year of the study and have a preliminary assessment, the experience continues. The results after the first year of research show the need to clarify the doses of fertilizers. In the following years, the cumulative effect of applying a complex of fertilizers is predicted.

Abstract. This article presents the results of testing a new-generation fungicide

on leached chernozem soils during potato cultivation.

Problem and Purpose. Potatoes are the most widely grown crop in our country,

occupying approximately 1 million hectares. However, potato diseases and

pests hinder their high yield and shelf life. The crop must be regularly

monitored for late blight, early blight, and other diseases. In most cases,

foreign-made fungicides are used. JSC Shchelkovo Agrokhim has developed a

new product, BELUJI, KS*, which needs to be tested on potatoes, which was the

purpose of this study.

Methodology. The study was conducted on leached chernozem soil of average

fertility at three farms in the Nizhny Novgorod region. The primary research

method was a comparison of potato cultivation patterns and plant protection

measures. Agricultural practices and research methods were generally

accepted. Weather conditions varied in terms of heat and moisture availability

during the study years, which was taken into account during scheduled potato

treatments.
