why are ammonium salts used as fertilisers?

Ammonium salts are sources of soluble nitrogen, so they can be used as 'nitrogenous' fertilisers .

But because quality synthetic fertilizers used in the right amounts are not dangerous, you can safely add just the right amount of the various nutrients that crops need, in addition to the organic fertilizer you are using.

Nitrogen is important to the chemical industry. It is used to make fertilisers, nitric acid, nylon, dyes and explosives. To make these products, nitrogen must first be reacted with hydrogen to produce ammonia.

Nitrogen, phosphorus and potassium, or NPK, are the “Big 3” primary nutrients in commercial fertilizers. Each of these fundamental nutrients plays a key role in plant nutrition. Nitrogen is considered to be the most important nutrient, and plants absorb more nitrogen than any other element.

Advantages of Organic Fertilizer: In addition to releasing nutrients, as organic fertilizers break down, they improve the structure of the soil and increase its ability to hold water and nutrients. Over time, organic fertilizers will make your soil–and plants–healthy and strong.

Ammonium sulfate provides lawns with readily available nitrogen and sulfur. It helps lawns green up quickly, helps in cold soils, and is relatively inexpensive. If too much ammonium sulfate is applied, an undesirable large amount of growth may result.

Quaternary ammonium salts (QAS) are cationic compounds containing alkyl groups in a chain length of C8–C18, which are water soluble and can be used as disinfectants in textile industries. All of these compounds are membrane active agents and can damage cell walls of gram-positive bacteria.

Ammonium chloride is prepared commercially by combining ammonia (NH3) with either hydrogen chloride (gas) or hydrochloric acid (water solution): NH3 + HCl → NH4Cl. Ammonium chloride occurs naturally in volcanic regions, forming on volcanic rocks near fume-releasing vents (fumaroles).

Although it is an ionic compound, it does not dissociate into its ions in water to any appreciable degree. - NH4+ (Ammonium ion) are soluble.

Synthetically manufactured urea is an organic compound which is not considered an 'Organic' fertiliser. Urea is naturally produced by a lot of animals as a metabolic byproduct and such natural urea is an approved Organic fertiliser.

To put it simply, weightlifters and powerlifters use ammonia smelling salts to get extra energy for a short amount of time to lift even more weight. It gives them an adrenaline rush, dulling pain in the muscles. Ammonia is most often used by powerlifters because they need the extra strength.

Ammonium salts are used as cleansing agents, food additives, diuretic, surfactants, antistatic agents and disinfectants. They are known to have antimicrobial activity. Osmotic pressure in cells is stabilized by quaternary ammonium salts.

While the use of nitrogen as a fertilizer has brought enormous benefits, the loss of fertilizer nitrogen to the environment also has many side effects, including reduced biodiversity and the formation of marine algal blooms.

Decomposition process in making organic fertilizers is time consuming, which delays the making of organic fertilizers. The main disadvantage of inorganic fertilizers is that it costs much higher than the organic fertilizers. So, if someone is using fertilizers in bulk, organic fertilizers are much more cost effective.

Urea: Urea is commonly used as a nitrogen source in many residential-use fertilizers. Monogastric animals such as dogs and cats tend to tolerate ingestions well, with gastrointestinal signs predominating. Large ingestions may result in methemoglobinemia (see Nitrates).

In addition to its use as a nitrogen fertilizer, anhydrous ammonia has other purposes on the farm. It has been used with high-moisture grains to control mold growth. When using it with grain, use the same precautions that you use when applying it as fertilizer.

Fertilisers are formulations which may contain nitrogen, phosphorus and potassium compounds to promote plant growth. Fertilisers that supply all three elements are often called NPK fertilisers, after the chemical symbols for these three elements.
