Air pollution specifically particulate matters (aerosols) affect global warming. Air pollution is caused by gases, dust, fumes or odor in harmful amounts. Aerosols are a subset of air pollution that refer to the tiny particles suspended everywhere in our atmosphere. These particles can be both solid and liquid, and are collectively referred to as ‘atmospheric aerosol particles’. In modern days, most of these are produced from human industrial and agricultural activities. In clear air, particles of sizes of approximately 0.1 to 1 micron interact with the solar beam. Particles containing little carbon are effectively ‘white.’ They reflect solar radiation, making the air and Earth surface below them a bit cooler than they would otherwise be. In contrast, particles containing substantial amounts of black carbon (e. g., soot, which is typically produced from combustion of fossil fuels, bio-fuels, and biomass burning) warm their surroundings by absorbing solar radiation before it reaches the ground. When water vapor clings to water soluble particles in the same size range (~0.1 to 1 micron), it creates cloud droplets in the lower troposphere, but literatures on Sulphur use efficiency of wheat crop under varying level of Sulphur applied as aerosol as well as foliar feeding, are inadequate. Here, an attempt has been made to introduce about the aerosols, and particularly, to reflect the roles of Sulphur aerosol on various processes of plant growth and development with special emphasis on its use efficiency.
