Sustainability of the use of agricultural machinery and its on the environment

The main types of negative impact of technology on the natural environment are gaseous, solid and liquid emissions, heat emissions, resource depletion. As a result of repeated movement of machines across the field, there is a significant over compaction of the soil, which spreads to a great depth (up to 100 cm), and machine tracks cover up to 80.0% of the field. Soil density increases by 20.0-40.0% under the influence of heavy machinery. Exhaust gases are the main source of toxic emissions. They are a mixture of gaseous products of complete and incomplete combustion of fuel, excess air and various trace impurities. Diesel engines are extremely toxic due to their high content of , benzene, aldehydes and soot, although they have significantly lower  and  emissions compared to gasoline engines. Carbon monoxide ( ) is the leader among harmful substances in terms of absolute emissions. Its figure is 10.3 million tons per year. Nitrogen dioxide ( ) is on the second place with 1.8 million tons per year. Hydrocarbons ( ) are on the third place with 1.5 million tons per year. The priority belongs to , lead ( ), sulfur dioxide ( ) and soot particles in terms of environmental hazard. It is necessary to ensure the reduction of emissions of these substances in the first place. Emissions of ,  and benzopyrene play a significant role in air pollution. At first it is necessary to ensure the reduction of emissions of these substances.
