The study is based on a Polish experiment (2021) in the territory of the Plovdiv region in the central part of the Republic of Bulgaria. The study was conducted with a nine-meter precision seed drill, aggregated to a 302 kW tractor when sowing silage corn. Using the service diagnostic program, graphic dependences describing the consumption of AdBlue® in relation to the operating temperature and the consumed diesel fuel have been extracted. Factors influencing AdBlue® consumption were monitored: operating temperature, diesel quality, and tractor engine load. It has been found that any drop in temperature, whether influenced by external factors or by the tractor engine, appears to be a determining factor for AdBlue® dosing. The consumption of AdBlue® for 8 hours of working change of the machine-tractor unit was monitored and it was found that the consumed amount of liquid reagent is 37.5% of the entire tank and the consumption of diesel fuel is 68.75%.
