Annamalai University Study Centre

Annamalai University Study Centre N is one of the most abundant forms of nitrogen found in soils. It is present in both soluble and insoluble forms. Soluble nitrates are generally considered the most effective form of nitrogen fertilizer for crop production. However, their rapid leaching rates make them less desirable than slow-release or residual nitrogenous fertilizers. Nitrate-N is commonly applied as a foliar spray at planting or a topdressing at the beginning of flowering.


Ammonium-N is another form of nitrogen that occurs naturally in many types of soil. When applied as a foliar fertilizer, ammonium-N moves rapidly through the root zone and is rapidly converted to nitrate-N via microbial action. Like its counterpart, nitrate-N, ammonium-N is applied primarily as a foliar spray.

Urea-N is a highly reactive form of nitrogen that can be applied directly to the soil surface or incorporated into the soil profile. In general, urea-N is not recommended for use as a foliar application, due to the high cost involved in its manufacture and poor conversion efficiency relative to other N forms.

Diammonium phosphate (DAP)-N

Diammonium phosphate (or diammonium phosphate) is the only N-P-K fertilizer used commercially today. As a fertilizer, it is often referred to as a complex N material, because it contains several different forms of nitrogen, phosphorous, and potassium. Diammonium phosphates are relatively inexpensive and have good conversion efficiencies, making them ideal for fertilizing crops.

Nitric acid (HNO3)-N
Nitric acid (or nitric oxide), also known as nitric oxide gas, is a strong oxidizer used mainly for the synthesis of metals and explosives. Nitric acid is produced industrially by passing ammonia over heated copper rods, generating nitric oxide gas. The gas mixture then passes through water scrubbers to remove excess ammonia. This method of synthesis results in the formation of nitrogen oxides and nitrous oxide, which may be harmful to human health if inhaled.

Ammonia (NH3)-N
Ammonia is a colorless gas with a characteristic pungent odor. It is widely used in industry as a reagent in chemical manufacturing processes. It is toxic to humans and animals, causing severe burns on contact and inhalation.

Sodium nitrate (NaNO3)-N
Sodium nitrate is a white crystalline solid that dissolves in water to give a solution containing sodium ions and nitrate ions. The concentration of dissolved salt in the soil determines whether the soil is classified as salty or non-salty. Salinity levels vary greatly across regions, ranging anywhere from 0 mg/L up to 5,000 mg/L. Salt concentrations above 1,500 mg/L adversely affect plant growth and yield.

The study center is a very useful platform for students who are looking to further their education. It provides students with a lot of resources and opportunities to learn and grow. The study center is a place where students can come to find lots of information and resources to help them with their studies. It is also a place where students can come to relax and unwind after a long day of studying. The study center is also a place where students can meet and mingle with other students who are studying the same topics as them. Studying with other students is a great way to help each other learn and grow as well.
