Nitrogen

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…

agricultural research shows that deliberately increasing SOC raises the health and amount of food produced of crops and improves pastureland for grazing livestock. Decomposition of plant and animal material in the soil also releases other nutrients such as nitrogen and phosphates, which are vital for plant growth. SOC also changes the overall soil composition it increases the amount of water that can be absorbed and stored, improves gas exchange, and breaks up the soil, making it easier for…

A 2010 survey of 14 industrialized countries found that skepticism about the danger of global warming was highest in Australia, Norway, New Zeeland and the United States, in that order, correlating with high per capita emission of carbon dioxide(Wikipedia). Furthermore there are so many ways society is damaging the ecosystem, some of these issues are brought upon by nature, but the majority of them are caused by man-made pollutants. One issue that is becoming large scale is global warming.…

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…

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…

The Anthropocene is an era characterized by humans’ intercontinental impact on ecological systems and processes (Steffen et al. 2011). Monitoring ecosystem function and fluctuation is the primary interest of Dr. David Lewis, who examines variables associated with the Anthropocene, including: land modification, nutrient cycling, hydrologic perturbations, and climate change. Many anthropogenic activities result in heightened nutrient inputs into the environment (Foley et al. 2005), including land…

Earth, a planet that once was devoid of human, an organism that destroys anything and everything in its path, is currently infected with it. After a prosperous five billion years, Earth is sinking and anything on it will go down too. Everyday, Earth is suffering from an endless beating of human destruction: forests are mowed for land, coals are burned for energy, and oceans are polluted for space. The consequence doesn 't only hurt the Earth itself but everything on it. Such large-scale…

Fritz Haber was a German chemist who won the Nobel Prize in 1918 for "improving the standards of agriculture and the well-being of mankind". Yet the same process that landed him the highest honor for saving many lives ended up taking just as many away. He threw himself into the World War I by making bombs out of the love of his country. In the Radiolab Podcast about Haber and "What's Eating America" by Michael Pollard talks about how hard it is to place Haber under the category of good or evil.…

imbalance in biogeochemical cycling and lead to problems such as cultural eutrophication and fish kills. Biogeochemical cycling is defined as the chemical element flow between the living and nonliving components of the ecosystem. This is the cycle of nitrogen, phosphorus and carbon being converted into organic substances of plants and animals that are released back into the environment. There are three ways that human activities cause an imbalance of biogeochemical cycling on a daily basis. The…

how it interacts with herbicides. The lab showed the participants on a small scale how eutrophication occurs and how it doesn't take a long time for algae to take over an area. Nitrogen and Phosphorus are usually found in fertilizers but not always at the same time. A study done said “ Concentrations of phosphorus and nitrogen in surface waters are being regulated in the United States and European Union. Human activity has raised the concentrations of these nutrients, leading to eutrophication…
