Duties and areas of work

1. General duties

The Department of Soil Agrochemistry and Optimization of Plant Nutrition is the unit that carries out the Institute’s research in agrochemistry and plant nutrition. It is responsible for assessing the agrochemical state of soils; studying the cycling, transformation and uptake of nutrients in the soil–plant–water system; determining the nutrient requirements of crops; developing optimal, balanced and site-specific fertilization systems; improving the scientific basis for efficient fertilizer use; and developing methods, recommendations and guides based on research results.

The department’s main goal is the comprehensive assessment and monitoring of the agrochemical state of soils and their nutrient supply using modern laboratory methods, digital mapping and GIS; determining the patterns of nutrient cycling, transformation, balance and uptake in the “soil–plant–fertilizer–water–climate” system; developing precise and resource-saving fertilization technologies based on precision agriculture and digital agrochemistry; and developing and introducing modern methods, guidelines and manuals on agrochemical assessment, nutrition diagnostics, fertilization and nutrition management.

2. Main duties

integrated assessment of the agrochemical state of soils, determining the supply of macro- and micronutrients based on GIS and digital mapping, and continuous agrochemical monitoring;

calculating the agrochemical nutrient balance by modelling interactions in the “soil–plant–fertilizer–water–climate” system and developing science-based fertilization systems;

determining optimal fertilizer rates, ratios and application times for crops based on agrochemical and physiological requirements and introducing resource-saving technologies;

improving the agrochemical basis for producing environmentally safe, high-quality agricultural products through balanced and differentiated nutrition systems;

agrochemical assessment of nutrient uptake efficiency of crops under abiotic stress (salinity, drought, high temperature) and developing stress-resilient nutrition management;

developing a plant nutrition diagnostics system (leaf analysis, rapid tests, spectral and sensor technologies) and fertilization models based on the “exact need – exact rate” principle, and introducing them into practice;

forecasting nutrient cycling with digital agrochemistry and “smart farming” technologies and creating intelligent decision-support models and software platforms;

comprehensive assessment and optimization of the ecological sustainability and economic efficiency of nutrition systems based on agrochemical, energy and resource-saving indicators.
