Nitrogen is used by plants in order to synthesize protein peptide bonds and for cell growth. Not

The nitrogen in the atmosphere goes into the soil. The bacteria surrounding the plants change the state of the nitrogen so the plants can absorb it. Animals then get their nitrogen from the plants. This cycle is very important because plant life and wildlife cannot live without it. Its an important part of cells and processes like amino acids, proteins and DNA. Its also the key ingredient in creating chlorophyll for plants. Unfortunately humans have been able to alter the cycle. By inserting fertilizer into the soil, it puts more nitrous oxide gas into the atmosphere. This then upsets the balance of the cycle.

High amounts of nitrate from agricultural field watershed contaminate the groundwater, creating a consumption hazard. A nitrate level greater than 10 mg/L causes negative health effects for the local population and aquatic organisms.

Therefore, a 20-day laboratory incubation experiment was conducted to evaluate the influence of nitrification inhibitors on N2O, CO2 and CH4 emissions after the incorporation of broccoli crop residues on a heavy-clay, vertosol soil from Gatton, South East Queensland, Australia. Five treatments were investigated including the conventional fresh broccoli residue incorporation, with the addition of three nitrification inhibitors: 3,4-dimethylpyrazole phosphate (DMPP), 3,4-dimethyl pyrazolium glycolate (DMPG), and PIADIN. The incorporation of dry broccoli residues was also investigated. Samples were incubated at 25 ̊C across varying soil moisture

During World War 1 scientists discovered a process which involved taking the nitrogen from the air and turning it into usable ammonia. Most of the ammonia acquired by this process has been used as fertiliser. Upon evaporation, the ammonia proceeds to turning into acid rain. A few attempts have been made to control agricultural nitrogen emissions however, no steps have been taken to regulate agricultural ammonia emissions. Ammonia emissions also come from animal feeding operations. When the ammonia rises into the air and then falls back to the ground, it is broken into nitric and nitrogen acids which can kill plants and fish.

In the year 2014 37.1 million metric tons of nitrogen was applied to cornfields in the United States.9 161.4 kg/ha was the average amount per acre utilized.9 According to the United States Department of Agriculture Economic Research service, applying nitrogen at the proper rate, at the correct time, utilizing suitable methods of application are important factors for nitrogen management.10 According to the United States Geological Survey 52% of nitrogen that flowed into the Gulf of Mexico was the result of corn and soybean agriculture.11 High amounts of nitrogen and phosphorous cause a bloom of algae, that later die and cause this area in the ocean to become hypoxic.12 Phosphorus plays a crucial role in plants. Since it's a component of nucleic acids, phosphorus plays a vital role in plant reproduction. Moderate amount of phosphorus results in higher grain production but too much can harm the crops.

Both height and weight of the tomato plant are negatively affected when more plants are grown in the same amount of space. This increase in plant density causes increased intraspecific competition between plants for limited resources. As a result, these tomato plants grow less tall and weigh less. These plants could be competing for nutrients in the soil. Liu et al. (2016) found that nitrogen in the soil, in the form of either NH4+ or NO3-, is often highly competed for among plants and other organisms. Inn addition, Pankoke et al. (2015) found nitrogen competition to have the biggest affect on plant biomass. Data from Liu et al. (2016) discovered a natural solution that plants and organisms have adapted to help with this competition over nitrogen in the soil. It was concluded that some organisms and plants would absorb the nitrogen from different soil depths. Plants acquire nearly seventy percent of their nitrogen from the top five centimeters of the soil. As a result, more nitrogen is available deeper in the soil for organisms. The issue in intraspecific competition is that all of the plants are the same species, and therefore have the same roots to draw nitrogen from the same depth of soil. When more plants are added to the same amount of soil, there are more roots competing at the same depth for limited about of nitrogen in the

formation. Even though vegetables also contain high levels of nitrates and nitrites, they are rarely

In recent decades humans have been playing an increasingly large role in the nitrogen cycle. Not all of the ways humans have been affecting the cycle have been negative, but the vast majority have been. One key thing that has human activity that has been disrupting the nitrogen cycle is the burning of fossil fuel. This burning releases carbon into the air at unnatural rate, and thus alters the amount of nitrogen in the atmosphere. This has had far reaching effects that no one first thought of and is now affecting the plant and animals in Acadia National Park. Another human activity that has increased massively over the past few years is industrial nitrogen fixation. This process is used to create fertilizer with high amount of nitrogen in it.

The purpose of this research is to find out how nutrients, such as phosphorus and nitrogen affect plant growth. To find out how the plants are affected by growth in the different nutrient treatments. With the results found, what does this suggest about how people should fertilize the soil in which people grow food crops. Using the species of grass rye, the research investigates the effect of the absence of nitrogen and phosphorus.

Nitrogen is essential for all forms of life in that it is required to biosynthesize basic building blocks of plants, animals and other life forms. Atmospheric nitrogen is relatively inert; however, the fixation process can free up the nitrogen atoms from their diatomic form (N2) to compound form (NH3) so they could be used in many ways. Biological nitrogen fixation provides about 65% of the biosphere’s available nitrogen, and most of this is done by the cooperation between legume and rhizobia. In fact, symbiotic nitrogen fixation by rhizobia in legume root nodules injects approximately 40 million tonnes of nitrogen into agricultural systems each year.

Nitrate is commonly written as NO3 and is vital to all living organisms. It is mostly common with plants because it serves as a plant nutrient and it also helps plants produce seeds (4). Nitrates in freshwater have a direct effect on fish and aquatic life. It may cause the environment to be harsh for fish to live in. Aquatic life such as Algae and other plants use nitrates as source of food. Large amounts of algae can cause extreme measures in dissolved oxygen. Algae and other plants can produce and generate oxygen during the day, but at night will decrease at low levels and this will result in large numbers of bacteria feeding on dead algae or other plants. In water quality, there are to processes known as Eutrophication and Anoxia The process in which a body of water requires high concentration of nutrients especially nitrates. As the

The increasing use of artificial fertilizers, the disposal of wastes (particularly from animal farming) and changes in land use are the main factors responsible for the progressive increase in nitrate levels in groundwater supplies over the last 20 years.” (Asami et al.) It is no easy task to discover a solution to agricultural nitrogen runoff that improves the water and organisms while also appeasing the industry. What we want to know is how can we help make a difference in these habitats right now that can be carried out with as little opposition from the agricultural industry as possible. We propose an experiment that may help to alleviate some of the nitrogen amounts washed into streams while the bigger problems are being addressed by other institutions. It could be a quicker way to help the ecosystems than waiting until one solution is reached. Our hypothesis is that with the addition of natural and native vegetation, the amount of nitrogen present in streams due to runoff will decrease more than if imported substances like gravel and sand were introduced. We believe this option will prove the most successful because it may cause less of a disturbance in the surrounding environment. The vegetation will be native, so the problem of introducing a non-native species won’t need to be addressed. The organisms in the stream also need to be taken into consideration and the addition of

Soil consists of billions of minute living organisms, bugs and rodents. (Weather video clip-soil, 2004) It is necessary that the mixture of these organisms, bugs and rodents work together to produce healthy soil. As plants, trees and carcass’ decompose, they produce phosphorus, which is required to have healthy vegetation in soil. Another key ingredient for healthy soil is nitrates produced by nitrogen in the air mixing with condensation of water leaking into soil, which also produces healthy soil. Too much of these chemicals, along with trace minerals, will pollute the soil. Humans rely on healthy, fertile soil to grow fruits and vegetables in as well as raise animals who eat from the products grown in healthy soil. When the organisms,

The nitrogen cycle is the exchange of nitrogen through the air, plants, animals, and the ground. First nitrogen goes through Fixation which changes the nitrogen into ammonia. Then the ammonia gets changed it to nitrates by bacteria in the process called Nitrification. The plants can now use the nitrates. Assimilation is how plants get nitrogen. They get the nitrates from the soil and the use the roots to take in the nitrates. Decaying plays a role in the nitrogen cycle. Through the process Ammonification a plant or animal decomposes and the

Recently, water and food pollution are the important global concern in environmental protection and human health due to their numerous harmful activities. There are many pollutants producing by human day-by-day including nitrate, fluoride, pesticides, mercury, lead, arsenic, and nitrite resulting from oil spills, burning of the fossil fuels, dumping waste and sewage of factories, and etc. Among them, nitrite was widely used in the food industry, pharmaceutical and agriculture as an additive in foods due to improve color and flavor, preservative in meat products due to its antimicrobial property, therapeutics and fertilizer. In addition, it was found in vegetables and water by using the nitrate fertilizers and from natural nitrogen cycle process as a major active intermediate ion of this cycle producing by reduction of nitrate or oxidation of ammonia. Nitrate has an important role in the formation of N-nitrosamines, hazardous compounds to human health, leading to be carcinogens. For example, nitrite reacts easily with amide and amine of foods in the stomach to generate N-nitrosamines, resulting in Blue Baby Syndrome, bowel and stomach cancer, and/or bind to hemoglobin of blood, producing methemoglobin who reduces the oxygen transport capability in human blood which causes the leukemia and brain tumor. The permissible concentration of nitrite in water according World Health Organization is about 3 mg L-1 1. Therefore, the accurate quantitative monitoring of nitrite
