The basic uses of nitrogen

Nitrogen is used nowadays in a wide range of activities. Its range of use varies from food industry to medical purposes. In agriculture, almost all commercial fertilizers are nitrogen based. In large amounts, such fertilizers erode and decay the soil and pollute the waters, but when they are used correctly, they contribute to extend food production. Natural fertilizers also release nitrogen, but they are more environment friendly. Nitrogen is being used in laboratories and medical facilities for preserving different organisms and in producing cures for diseases such as Anthrax. In medicine, liquid nitrogen is used in performing surgeries. The general advantages of this therapy are its ease of use, its low cost, and its good cosmetic results. Most skin cancers are treated with excision or other destructive procedures, such as electrodessication and curettage. Superficial basal cell skin cancers and Bowen disease can be treated with liquid nitrogen instead. Nitrogen has recently been used in beer production. Many beers use it as an ingredient. Brewers dissolve nitrogen in the beer, which improves the beer's quality. The right blend between CO2 and nitrogen preserve the composition of beer and prevent or reduce foaming. As an extent, nitrogen is also used to fill tires. Ingersoll-Rand's Productivity Solutions Group has introduced the Nitrogen Tire Filling System, which enables tires to perform better, last longer and function with a greater degree of safety than tires filled with ordinary compressed air. A dry, inert gas used by racing professionals and the military to inflate race-car tires and military vehicles, this gas leaks through a tire's rubber walls three times more slowly than oxygen. As a result, tires filled with this high-quality gas, delivered by IR's Tire Filling System, stay inflated longer, and therefore grip the road better and provide greater control, in all weather conditions. It is a clean, moisture-free gas that slows down the tire aging process, unlike oxygen, for example, that is known to erode the rubber on the interior. Nitrogen also solves issues like improper tire inflation and excessive heating, which can lead to catastrophic tire failure, thus causing serious accidents.
