Urea & Ammonium Nitrate. The combination form, also called UAN, is a uniform, dry product of ammonium nitrate and urea. Its nitrogen content ranges from about 28 to 32 percent.

en.wikipedia.org/wiki/Ammoniacal_nitrogen

Ammoniacal nitrogen (NH 3-N), is a measure for the amount of ammonia, a toxic pollutant often found in landfill leachate and in waste products, such as sewage, liquid manure and other liquid organic waste products. It can also be used as a measure of the health of water in natural bodies such as rivers or lakes, or in man made water reservoirs. The term is used widely in waste treatment and ...

The ratio of nitrate to ammoniacal nitrogen in a fertilizer determines the rate of substrate pH change and can even be used to correct pH during production. The pH changing property is known as a fertilizer’s potential acidity or basicity and is listed on a fertilizer’s label (Table 1). ...

Summary – Ammonia vs Ammoniacal Nitrogen. Ammonia and ammoniacal nitrogen are two related terms. The difference between ammonia and ammoniacal nitrogen is that the ammonia is an inorganic compound having the chemical formula NH3 whereas the ammoniacal nitrogen is a measure of the amount of ammonia in a sample.

Ammoniacal Nitrogen. Ammoniacal nitrogen is nitrogen derived from ammonia and is one form of nitrogen that plants can readily use. Ammoniacal nitrogen is most commonly found in the soil as ammonium, which is created naturally by the nitrogen cycle or introduced through synthesized fertilizers and deposited into the soil for plant use.

Nitrogen vs Nitrate Nitrates are highly available anionic forms containing nitrogen. Naturally, nitrogen exists as a gas, and it is the main reservoir of nitrogen. This nitrogen cannot be directly utilized by the plants, so it is converted into water soluble forms like nitrates, nitrites or ammonium. Atmospheric nitrogen is converted to nitrate through industrial […]
