SHANGHAI, Oct 25 (Bernama-AsiaNet) — Good air quality has a huge impact on the output and quality of agricultural products. This was amply proved by American research, which showed that the improvement in air quality in the United States from 1999 to 2019 was one of the main reasons for the increase in corn and soybean production.
The researchers collected data on ozone, suspended particulates, nitrogen dioxide and sulfur dioxide content provided by air quality monitoring stations and satellite telemetry stations in nine American states, as well as crop yield data in various regions for comparative analysis.
