What Is Ammonium Nitrate Fertilizer Used For

Many countries are phasing out its use in consumer applications due to concerns over its potential for misuse.[6] Accidental ammonium nitrate explosions have killed thousands of people since the early 20th century.Ammonium nitrate is found as the natural mineral gwihabaite (formerly known as nitrammite)[7] – the ammonium analogue of saltpetre (mineralogial name: niter)[8][9] – in the driest regions of the Atacama Desert in Chile, often as a crust on the ground or in conjunction with other nitrate, iodate, and halide minerals.The industrial production of ammonium nitrate entails the acid-base reaction of ammonia with nitric acid:[10].As ammonium nitrate is a salt, both the cation, NH 4 +, and the anion, NO 3 −, may take part in chemical reactions.The red–orange colour in an explosion cloud is due to nitrogen dioxide, a secondary reaction product.One practical consequence of this is that ammonium nitrate formed as solid rocket motor propellant develops cracks, leading to the development of phase stabilized ammonium nitrate (PSAN), which incorporates metal halides as stabilisers.Ammonium nitrate's advantage over urea is that it is more stable and does not rapidly lose nitrogen to the atmosphere.ANFO is a mixture of 94% ammonium nitrate ("AN") and 6% fuel oil ("FO") widely used as a bulk industrial explosive.[17]: 1 It is used in coal mining, quarrying, metal mining, and civil construction in undemanding applications where the advantages of ANFO's low cost, relative safety, and ease of use matter more than the benefits offered by conventional industrial explosives, such as water resistance, oxygen balance, high detonation velocity, and performance in small diameters.In November 2009, the government of the North West Frontier Province (NWFP) of Pakistan imposed a ban on ammonium sulfate, ammonium nitrate, and calcium ammonium nitrate fertilizers in the former Malakand Division – comprising the Upper Dir, Lower Dir, Swat, Chitral, and Malakand districts of the NWFP – following reports that those chemicals were used by militants to make explosives.Due to these bans, "Potassium chlorate – the stuff that makes safety matches catch fire – has surpassed fertilizer as the explosive of choice for insurgents.Ammonium nitrate is used in some instant cold packs, as its dissolution in water is highly endothermic.In 2021, King Abdullah University of Science and Technology in Saudi Arabia conducted experiments to study the potential for dissolving ammonium nitrate in water for off-grid cooling systems and as a refrigerant.It was once used, in combination with independently explosive "fuels" such as guanidine nitrate,[20][21] as a cheaper (but less stable) alternative to 5-aminotetrazole in the inflators of airbags manufactured by Takata Corporation, which were recalled as unsafe after killing 14 people.A solution of ammonium nitrate with nitric acid called Cavea-B showed promise for use in spacecraft as a more energetic alternative to the common monopropellant hydrazine.Pure ammonium nitrate does not burn, but as a strong oxidizer, it supports and accelerates the combustion of organic (and some inorganic) material.While ammonium nitrate is stable at ambient temperature and pressure under many conditions, it may detonate from a strong initiation charge.Molten ammonium nitrate is very sensitive to shock and detonation, particularly if it becomes contaminated with incompatible materials such as combustibles, flammable liquids, acids, chlorates, chlorides, sulfur, metals, charcoal and sawdust.Contact with certain substances such as chlorates, mineral acids and metal sulfides, can lead to vigorous or even violent decomposition capable of igniting nearby combustible material or detonating.For example, in Australia, the Dangerous Goods Regulations came into effect in August 2005 to enforce licensing in dealing with such substances.[33] Licenses are granted only to applicants (industry) with appropriate security measures in place to prevent any misuse.Ammonium nitrate decomposes, non-explosively, into the gases nitrous oxide and water vapor when heated.[39] Large stockpiles of the material can also be a major fire risk due to their supporting oxidation, a situation which can easily escalate to detonation. .

Clay particles are the reactive portion of the soil; sand and silt comprise the soil skeleton.Although there are many different compositions of clay, this chapter will use the general category of silica clays as an example of how these surfaces interact with the soil solution.Clay particles usually have negative charges because of unsatisfied valences at the crystalline edges of the silica and alumina plates.Soil chemical reactions are largely driven by the oxide and hydroxides available on these surfaces (Brady and Weil, 2007).Dissolved cations form an outer layer around the clay surface (Hiemenz, 1986).These charges allow water molecules to tightly adsorb the clay surfaces (hydrophilic), ensuring that water is available to create the soil solution.This interaction between anionic particle surfaces and dissolved cations is important to aggregate stability (i.e., structure). .

Ammonium nitrate was the first solid nitrogen (N) fertilizer produced on a large scale, but its popularity has declined in recent years.The production of ammonium nitrate is relatively simple: Ammonia gas is reacted with nitric acid to form a concentrated solution and considerable heat.Manufacturers produce granular ammonium nitrate by repeatedly spraying the concentrated solution onto small granules in a rotating drum.These additives lower the N concentration and are sparingly soluble, making the modified product less suitable for application through an irrigation system (fertigation).Ammonium nitrate is commonly mixed with other fertilizers, but these mixtures can’t be stored for long periods because of a tendency to absorb moisture from the air.When the barrier separating the bags is ruptured, the ammonium nitrate rapidly dissolves in an endothermic reaction, lowering the pack’s temperature to 2 to 3 degrees Celsius within a very short time. .

Ammonium sulfate has a salt index of 3.25, which may result in temporary forage damage due to burning when applied at extremely high rates.Urea has become a popular N source due to the high N concentration (~46%) and consequent lower cost associated with transport.Most commercial inorganic fertilizers should be applied when the forage is actively growing, preferably at the beginning of the season (early spring).Therefore, time and rate of application are critical factors that can impact the effectiveness of organic sources for providing N to pastures.In addition, organic sources typically contain excessive P concentrations than is required by the forage when application is based on N due to the lesser ratio of N:P in the manure compared to crop demand [58].In addition to nutrient availability, factors such as source, time and rate of application, and environmental conditions can impact the effectiveness of organic materials in providing N to pastures.Management of organic fertilizer sources such as animal manure, broiler litter, or biosolids is more complex than that of inorganic fertilizers, primarily because the nutrient composition of organic sources is extremely variable, and not all nutrients are available immediately for plant uptake.Choice of fertilizer source will ultimately rely on goals in production, environmental and regulatory constraints, cost, and availability of materials. .

The tragedy is one of the largest industrial accidents involving the explosive chemical, and it hit Lebanon amid the coronavirus pandemic and an economic crisis.About 2.5 kilometres away, in the city’s port, a powerful explosion had sent a huge orange fireball into the sky, followed by a massive shock wave that overturned cars, damaged buildings and shook the ground across the Lebanese capital.Lebanese authorities say that the explosion, which killed at least 220 people, injured more than 5,000 and left an estimated 300,000 people homeless, was caused by 2,750 tonnes of ammonium nitrate, a chemical compound commonly used as an agricultural fertilizer, which had been stored for 6 years at a port warehouse.The blast is one of the largest accidental ammonium nitrate explosions ever recorded (see ‘Explosive chemical’) — so powerful that it was heard more than 200 kilometres away in Cyprus.Lebanon was also already reeling from an economic crisis that triggered anti-government protests starting in October 2019, when the country’s currency began to lose its value against the dollar, says Charlotte Karam, a social scientist at the American University of Beirut. .

The horrific explosion that devastated Beirut on August 4, 2020, has receded, but the physical damage and human distress persists.Like other explosives, these comprise a molecular mix that releases energy suddenly, most often accompanied by the production of heat, light, gases, pressure and deafening sound.In his Nobel acceptance speech, Haber acknowledged only that his discovery would help feed the world by improving soil fertility with ammonia.Studies have estimated that about half of the increase in the world population today owes its existence to nitrogen fertilizers.As the ammonia produced by petrochemistry can be used to make explosives as well as to fertilize soils, calculations of the number of people fed by the Haber-Bosch process should also perhaps take into account those killed in armed conflicts in the course of the 20th century.A mixture of 94% porous pellets of ammonium nitrate acts as an oxidizing agent when added to fuel oil (6% of the total volume) and can be used to create a basic but deadly explosive.More pertinent today, climate change is causing not only heat waves and flooding, but increased numbers of people are suffering from air pollution, which reduces life expectancy.Air conditioning can relieve heat stress during heatwaves, but the inequal access to cooling leads to a form of social injustice.Intensive agriculture uses more fertilizers and pesticides, so it too is related to loss of biodiversity and, in turn, increased chemical and air pollution.As a society, we need to change our mindset from the current fixation on growth as reflected by the gross domestic product of our economies – real alternatives exist.Travel restrictions enforced as the pandemic unfolded caused air pollution to drop significantly in many regions.The European New Green Deal is certainly a step in the right direction to achieve these goals, and hopefully, other economies will follow Europe’s lead. .

In one of the world’s deadliest industrial accidents, 567 people were killed in Texas in 1947 when 2,300 tonnes of ammonium nitrate detonated aboard a ship.We should learn from these catastrophes and make sure they don’t happen again,” said Stewart Walker, of the school of Forensic, Environmental and Analytical Chemistry at Flinders University in Adelaide.Anger has been mounting in Lebanon at the authorities for allowing huge quantities of the chemical to be stored near a residential area for years in unsafe conditions.Men ride a motorcycle past the damage near the site of Tuesday's blast in Beirut's port area, Lebanon August 7, 2020.Worldwide trade in ammonium nitrate in 2018 was worth $2.14 billion, with Russia the leading exporter, according to the Observatory of Economic Complexity, and Brazil the largest importer.The United States and Europe are the leading consumers of ammonium nitrates, according to London-based IHS Markit, accounting for just over half of global consumption in 2019.The United States does not maintain a public database on the locations of ammonium nitrate, meaning people do not know if they live near one, said Elena Craft, of the Environmental Defense Fund advocacy group. .
