Nitrogen cycle

The most likely causes for the dead zone in the Great Lakes are the amount of phosphorus nitrogen and fertilizer running off into the lake. When the lake becomes rich in these nutrients and you add warmer temperatures into the equation you can expect an algal bloom. Once the bloom dies the decomposition depletes much of the oxygen in the water which is severe because of the size of the algal bloom. This coupled with things such as low water inflow and temperature of water are the most popularly…

English chemist.(It’s Elemental- The Element Argon) These two chemists weren’t actually trying to discover this element. Stated at Argon- Element information, properties and uses | Periodic Table, they actually were trying to explain the density of nitrogen from air differed from that obtained by the decomposition of ammonia. It just so happened while they were trying to explain their theory they were able to discover the element Argon. Argon can be found in nature in a very little amount.…

Agricultural bacteria, fertilizers and manure that is distributed throughout fields causes a rise in the groundwater’s concentration that exceeds the max containment level for intake. These excess levels of nitrate found in water are extremely hard on the human body, and can be lethal in infants (Holme). Mixing water with formula to feed a baby is a perfect example of how nitrites can enter an infant’s immature digestive system. In 1999, a 3-week old in Wisconsin suffered from…

convert the nitrate to nitrogen that can be released into the atmosphere as gas. However, the scientists found a shocking result that the bacteria have only been eliminating 16% of all nitrogen pollution (Futurism). This is a matter that must be addressed, considering the percentages may drop lower over time. This oppression of nutrients has caused many complications and damage to our…

Discussion The cleanliness of tap water is determined by comparing many different factors of the water’s composition to the acceptable or ideal levels that have been set for “healthy” water. The water samples from each city show that the tap water remains within an acceptable range. For instance, the acceptable level for Nitrate in water is 10 ppm, a maximum level enforced by the Environmental Protection Agency, and each city did not exceed that amount with the highest level being 5 ppm in one…

Nitric oxide can be administered by a few different ways. When a patient is on a ventilator, nitric oxide is nebulized on the inspiratory cycle. Nitric oxide can also be given by a facemask or even a nasal cannula. The normal ranges for nitric oxide is 1 – 80 parts per million. High levels of nitric oxide can be very harmful and may even cause death, pulmonary edema or methemoglobinemia. A high concentration would be considered to be between 5,000 and 20,000 ppm. The length of time that…

A detailed description of soil locations, textures and physio-chemical properties can be found in Sections 2.3.1(page 41) and 3.3.1(page 56). We selected four types of soils out of seven types of soils, namely MGA, KBA, TAA and DUA. Key soil characterisation of these four soils is summarised in Table 4.2. The reason why these four types of soils were chosen for this chapter was that they had distinct soil parameters in terms of total organic carbon (TOC), Fe oxide, Al oxide, pH which have been…

produces heavy tonnage of biomass. Sugarcane biomass removes the largest amount micro and macro nutrients from the cultivated soil. For optimum production, a high-yielding variety desires more nutrients, particularly nitrogen besides other inputs. Sugarcane crop has a high requirement of nitrogen that usually exceed the natural transport capacity of soil through mineralization of organic matters (Garside et al. 2005). In China, farmers habitually apply 400–800 kg N, 150–300 kg P2O5 and 250–500…

Her work supported by both first-hand and second-hand research. In her analysis, she describes the natural nitrogen and ammonium levels in soil, followed by an explanation on how synthetic fertilizers negatively manipulate these levels. She details how this manipulation negatively impacts the microbial ecosystems within soil, which continues to have harmful effects…

detected, the most common reason for undertaking soil analysis is to detect the levels of essential nutrients (Guo, 2009). The commonly analysed nutrients in most samples submitted to the laboratory include macronutrients like potassium, phosphorus, and nitrogen as well as their pH levels. McGrath and Skotnikov (1996) pointed out that knowledge about soil nutrient levels, in addition to relative comprehension…
