Mathematical models developed on the basis of a big data array of stationary agrochemical field experiments of the Federal State Budgetary Scientific Institution "Federal Research Center "Nemchinovka" on different types (subtypes) of soils for calculating the potential yield and doses of fertilizers for the planned crop yield are presented. The combined use of such models with yield mapping data can potentially be used to identify areas of in-field heterogeneity in soil fertility.

The problem of overheating of electric motors of pumps of sewerage stations during the introduction of frequency converters of current is revealed. Modeling of the thermal state at different speeds of the rotor of the electric motor in the Comsol software package made it possible to determine the places for the possible installation of temperature sensors on the outer shell of the electric machine. Experimental studies have confirmed the adequacy of the obtained models and the proposed position of the temperature sensors.

The issues of reducing the import dependence of the domestic poultry meat industry are considered. The state of meat poultry farming in the world and in Russia, the dynamics of production of products of the sub-sector are analyzed. It was revealed that meat poultry farming is represented mainly by the cultivation of broilers of meat chickens, while there is a significant dependence on foreign breeding material. Measures have been formulated to reduce this dependence.
