NITROGEN

Nitrogen deficiency is easily identifiable because it causes yellowing of the old leaves, stunted stems on the plants and a lack of vigour. Nitrogen is a mobile nutrient that can be reassigned to plant tissues after mobilization in older leaves. Nitrogen is required to have lush vegetation... In many industries, ultra-pure nitrogen is used to zero and purge analytical instruments. Very high levels of purity are also required to meet the constraints of the semiconductor industry. Nitrogen generators are used to produce nitrogen from compressed air. They can produce nitrogen gas on site at a wide array of facilities... Industrial Oxygen and nitrogen gases are manufactured for use in industry. They are also abundant elements in nature, and they can be used in agriculture.
