Effects of Ammonia and Methods of Control
Ammonia can lead to big problems for broiler producers if not managed appropriately. Ammonia (NH3) is a form of nitrogen that has the potential to create odors, impact air and water quality, and animal and human health (1).
Ammonia is a colorless irritant gas, created from animal waste by microbial activity. By spending money to control the ammonia in houses they farmer has the potential to get that money back plus more in profit. Many farmers would tell you they have low levels of ammonia but the truth is we can’t smell the ammonia until it’s at 20PPM; however the human nose becomes accustomed to the smell. Ammonia levels of 50PPM in a broiler house can seriously stunt bird growth. With larger birds the loss can be half a pound per bird. Studies show that even levels as low as 25PPM can affect birds. Birds can become blind if exposed long enough to high levels of ammonia. Ammonia in the colder months when houses are closed up tight can cause runts in a flock. It is shown that high levels can create 10-15% runts. If runts are present what happens when drinkers and feeders are raised? The bird has no opportunity to mature and can’t be sent to the processing plant. Experiments have shown that 50 ppm ammonia will cause about a half-pound catch-time weight loss in a typical 7-week broiler growout. With 20,000 birds in the house and being paid at a rate of $0.045 per pound, this translates into $450 loss per house (6).
In addition to the negative impact of high NH3 levels in a poultry facility on birds, they cause health concerns for the caretakers in those facilities. High NH3 levels sometimes found in a poultry house have also become a cause of concern for the atmosphere outside the po...

...ough the aluminum + Ca(OH)2 mix did reduce ammonia losses by 57% . A follow-up study investigated the use of aluminum, ferric chloride, ferrous sulfate, and phosphoric acid on broiler litter. Each of these treatments resulted in a decrease in ammonia loss, but again aluminum was judged the best option, as ferric chloride is not cost effective, ferrous sulfate displays toxicity, and phosphoric acid contributes to phosphorus problems associated with land application. McWard and Taylor found similar ammonia reduction results when testing both alum and sodium bisulfate (2).
Ammonia will always play a major role in the poultry industry. How well you manage it, will depend on how successful your birds will be. As stated above there are many harmful thing that come with high ammonia levels and it should be regularly checked and maintained with adequate compounds or litter.
Nitrogen and nitrates relate to Hypoxia via the process of eutrophication. Since Nitrogen is a limiting nutrient in most waters, the added input of nitrate causes massive growth in algae. The algae rapidly consume all available N, and once the nutrient is limited again, the alga dies en masse. As the alga decomposes, oxygen is depleted in the water. This lowers dangerously lowers the level of dissolved oxygen in the water, which harms living organisms in the area. Small organisms and organisms that are immobile or unable to escape low-oxygen areas are particularly vulnerable. Hypoxia and resulting “dead zones” are harmful to local fishing and shrimping industries and algal blooms hurt the tourism industry. Hypoxia has lead to a decrease of about 25% in the brown shrimp habitat, forcing shrimping operations further offshore. As the hypoxia issue continues to grow, negative human effects will only increase. Since nitrate runoff from ag. has been proven to be the dominant source of hypoxia, policies could be enacted to effectively deal with “point-source” pollution. This makes enacting environmental policy more easily adapted, possibly included in past policy such as the Clean Water Act.

According to the article “Factory Farming Versus Environment and Society,” animal dung can be used as manure, however, “far too much of it is produced in factory farming… Lethal quantities of ammonia, potassium, hydrogen sulfide or other damaging chemical substances penetrate to ground waters and rivers with rain, thus poisoning them” (Fiut & Urbaniak 4). Animal manure contains toxic chemicals that polluted our water resources. The issue with having animals confined in a tight, restrictive environment is that animal feces leak through the cages and poison various water resources. Not to mention, it also makes the environment that produces our meat and dairy very unsanitary and more likely to increase the risk of transmitted diseases not only from animal to animal but to people who consume the meat as well. Moreover, when the feces contaminates the water, it affects the aquatic environment. In the article, Louis A. Helfrich, Richard J. Neves, and James Parkhurst stated, “nearly 20 percent of our freshwater fishes, 45 percent of our mussels, 48 percent of our crayfishes, and 20 percent of our aquatic snails are imperiled. Of the 230 species of amphibians (90 frogs and toads, and 140 salamanders) that depend on aquatic habitats, 40 percent are disappearing and alarming numbers of individuals are missing limbs; such deformities have been documented in 44 states”(Helfrich, Neves & Parkhurst 1). The pollution caused by factory farms kills the aquatic animals resulting in the declining loss of aquatic biodiversity. When the animal waste leaks from Lagoons, it not only causes toxicity to water but it can also create “dead zones” which the creatures can’t survive in. The nitrogen ends up becoming gaseous turning into a colorless gas with a pungent smell. This creates problems in
In mammals, ammonia excretion is unsuitable for disposing of nitrogenous waste on land. Mammals would have to urinate profusely to eliminate ammonia because of the toxicity, which would have to transport through the animal to be excreted in an extremely dilute solution. However...
within the soil. In this experiment, the liberation of ammonia is being employed as an indicator. Other components being utilized play a vital role in controlling the conditions of the experiment, as the THAM buffer, and the limitation of microbial activity, through toluene. The control experiment is crucial as it eliminates the addition of ammonia content being released by other sources within the soil into the final reading, providing accurate data.
Broiler chickens, luckily for them, only live up to 7 weeks old until they are big enough to be slaughtered. Their life starts out in incubator trays with hundreds and thousands of other chicks without enough head room to stand up, and not enough room to take 2 tiny steps. So for the first week of their lives it goes from cramp trays, to cramp boxes, to getting dumped onto the filthy floors of t...
...nts that are harmful are released. The factory farms have not only been seen to affect humans, but the animals also. The food given to these animals are supposed to make them grow faster, but it is also causing serious digestive problems for the animals. According to the Sustainable Table, “recent studies have shown that chemical additives in feed may accumulate in animal tissues, potentially exposing consumers to unwanted chemicals such as veterinary drug residues and heavy metals.” This is not fair for the animals and humans to have to suffer through something like this just so unhealthy food can be produced.
Anhydrous ammonia is stored as a liquid in pressurized tanks and after it has been sold to local farmers, they use it by injecting it directly into their soil where it then turns into a gas. It has a melting point of around -108 degrees Fahrenheit and an explosive range between a Lower explosive limit (LEL) of 15% and an Upper explosive limit (UEL) of 28% when mixed in air. Ammonium nitrate is typical found and used in its prill form where it is spread across the fields as a fertilizer. Ammonium Nitrate does not typical, under normal circumstances, pose an explosive hazard alone by itself but when combined with some sort of fuel it will act as an oxidizer during that process, literally adding fuel to the fire. “Both of these common fertilizers can become explosive under the right conditions.” (Fernandez & Schwartz, 2013)
According to “Meat the Truth”, a 2007 documentary directed by Karen Soeters, the film exposes the consequences of meat and dairy. It influences people about increasing the consumption of a plant-based diet and decreasing the intake of meat. Marianne Thieme, the narrator of the documentary and a Dutch politician who is a Member of the Party for the Animals in the Dutch Parliament, states, “Eating meat is the number one most environmentally destructive behavior, not cars, planes and power plants”. A consumer can make a great impact by changing their diet and restricting the consumption of meat. The transition to a plant-based diet is strongly informed by the film. Consumers have fallen into the advertising and marketing of meat to trigger minds the satisfaction of meat. Statistics from the Food and Agriculture Organization prove that from 1950 to 2000, the population of the world went from 2.6 to 6 billion and from this meat production increased five times as great. It is possible it can keep doubling this amount every fifty years if there isn’t a change that occurs. From the People for the Ethical Treatment of Animals, they state, “The Environmental Protection Agency (EPA) reports that roughly 80 percent of ammonia emissions in the U.S. come from animal waste.” Raising animals to

...an be placed in an unstable solution to decompose the free electrons and metal ion which will form metal amide and release hydrogen. Ammonia takes place in many chemical reactions and will react to form strong acids such as stable ammonium salts and ammonium chloride. As well as it forms ammonium nitrate(Ammonia).
When these agricultural resources are given to the animals involved in meat production, these resources are lost. Besides the loss of land, the process of animal production is contributing to pollution and other greenhouse gases that are doing irreplaceable damage to the environment and contribute to untold negative health
Nitrogen is used by plants in order to synthesize protein peptide bonds and for cell growth. Not only is this nutrient required in the largest quantity by plants, but it is also the most frequently limiting factor when it comes to productivity in crops. Plants cannot use nitrogen in the air and in the soil system it is lost easily. Because of this plants are forced to obtain nitrogen in the form of nitrate and ammonium from the soil. Too much nitrate can cause a negative effect on the plant including nitrate toxicity. High levels of nitrate are not only bad for plants but can also be dangerous to animals or humans in their presence. Here I discuss the scientific evidence of the effects of nitrate accumulation on plants and the environment and argue that too much nitrate accumulation can be harmful to its surroundings.
