Nitrogen is used today in a wide range of activities. The range varies from food use for medical purposes. In agriculture, nearly all nitrogen-based fertilizer business. In large quantities, such as fertilizers of soil erosion and decay and pollute the water, but when used correctly, help to increase food production. The natural nitrogen fertilizer, but they are environmentally friendly. Nitrogen is used in laboratories and medical centers for the preservation of various agencies in the production and cure of diseases such as anthrax. In medicine is liquid nitrogen used in performing surgery. The overall benefits of this therapy are ease of use, low cost and good cosmetic results. Most skin cancers are treated with excision or other destructive procedures such as electrocoagulation and curettage. Superficial skin cancers basal cell and Bowen's disease can be treated with liquid nitrogen instead. Nitrogen was used recently in the production of beer. Many beers as an ingredient. Brewers nitrogen dissolve in the beer, which improves the quality of beer. The right mix between CO2 and nitrogen retention of the composition of beer and prevent or reduce foaming. As nitrogen is used to fill the tires. Ingersoll-Rand Productivity Solutions Group, nitrogen tire filling system, allowing the tires to perform better established, longer and function with a greater degree of certainty that tires filled with regular compressed air. A dry, inert gas used by career military and racing tires and military vehicles blown up, that the leakage of gas through a rubber tire wall three times slower than oxygen. As a result, tires filled with these high quality gas, supplied by IR tire filling stay inflated longer, and thus grip the road better and offer more control, at any time. This is a clean and moisture free gas that slows the aging band, unlike oxygen, for example, is known to erode the rubber on the inside. Nitrogen also solve problems such as improper tire inflation and excessive heat, which can lead to catastrophic tire failure, causing serious accidents.
