Nitrogen College Essays Samples For Students

Human beings have altered the entire environment through the use of excessive nitrogen fertilizers to increase the yield of harvest. Most of the farmers in the entire world have opted to use the manufactured nitrogen manure rather than using organic manure. A large amount of nitrogen fertilizer that the farmers use in farms is not used up. Some usually evaporates into the air while the other sinks dip into the soil reaching the water table (Pollan 3). This is harmful as it causes acidic rainfall and contaminates of drinking water respectively ←THESE SENTENCES SUMMARIES THE CAUSES/ EFFECTS OF EXCESSIVE ...

Increasing concentrations of nitrogen in the environment, a phenomenon called as nitrogen saturation occurs when the inorganic nitrogen levels exceeds the demand by organisms and plants. Increased concentrations of nitrogen have detrimental impact on the air quality, owing to the oxidizing capacity of nitrogen oxides and their function in the formation of ozone layer .
Excessive nitrogen deposition causes an increase in foliar nitrogen content, which subsequently leads to increase in tree growth . Other negative effects on the ecosystem are frost-hardiness in conifer trees in the presence of large doses of nitrogen. Excessive nitrogen concentrations may also lead to tree ...

Crude oil is obtained from layers of sedimentary rock that are formed by materials which are eroded and carried away from the land surface by flowing water bodies. The water flows and drains into oceans, depositing sedimentary rocks in the ocean beds. Pools of crude oil, are present underground, trapped between layers of sedimentary rocks. Crude oil and natural gas are organic hydrocarbons. Petroleum in particular, is a complex mix of organic compound and contains traces of porphyrin. The structure of porphyrin is similar to that of chlorophyll and hemoglobin of plant and animal origin respectively. While natural porphyrin ...

The earth’s atmosphere can be defined as a series of progressively arranged “shells” or “spheres” held to its position by the force of gravity. Just to mention, the earth’s atmosphere exerts pressure to the earth’s surface which is referred to as the atmospheric pressure. In addition, the earth’s atmosphere covers a region of about 480 kilo meters around the earth’s surface after which exists the exosphere. Also, the earth’s atmosphere is further divided into heterosphere and homospere. Homospere is the layer 80 kilo meters just above the earth’s surface that has a uniform chemical composition ...

Food security remains one of the challenges facing the world today. Nations across the globe have embraced mechanized agriculture, which encourage use of synthetic fertilizers, reclamation of wetlands, and use of chemicals thus interfering with soil fertility, marine life, ground water, and estuarine environments. Synthetic fertilizers contain high levels of nutrients such as nitrogen, calcium, ammonia, phosphate, phosphorus, and magnesium, which increase crop yields and maturity. However, prolonged use of synthetic fertilizers has detrimental effects on the environment as it alters nitrogen cycle and facilitates accumulation of nitrogen compounds in water, soil, and atmosphere. Large amount of nitrogen in ...

Importance of Nitrogen and phosphorus to plants

Phosphorus and nitrogen is considered the essential nutrients required by the plants. They are required in larger quantities and thus known as the macronutrients. Each of the nutrients has its specific roles in plant development. Nitrogen mineral is the major component of most of the organs in plants. It constitutes approximately 40% to 50% of the dry matter of protoplasm, composes amino acids. It is also considered the major constituent of the building blocks of proteins. The nitrogen deficiencies result in slower or stunted growth and visible effects chlorosis (Nurzyńska-Wierdak et al., 2012). The plants that have been ...

Fermentation

Inoculation of yeast is the second step in the fermentation process during making of white wine. It requires concentrated sulphates, typically with the concentration of 10 g/hl, to be added into the juice. Such approach allows stimulating the participating fermentors and inhibiting the action of spoilage microflora. In the next step, the starter juice has to go through the process of spontaneous fermentation, before it can be added into the tanks, which have been freshly filled, maintaining the concentration of 2-5%. The fermentation process dynamics in this case is largely dependent on the inherent strain of the yeast.

Air pollution impacts the human health and the environment in various ways - by direct and immediate threat (smog, etc.) to the slow and gradual destruction of the body's various life-support systems. In many cases, air pollution negatively affects the structural components of the ecosystem to such an extent that the regulatory processes are not able to return to their original state and thus the homeostasis mechanism fails.
The atmosphere is the air shell of the Earth. Air quality involves the totality of its properties, reflecting the level of exposure to physical, chemical and biological factors on humans, plant ...

Several human activities influence the earth unfavorably. A stone crusher includes a great deal of suspended particulate matter and clamor into the air. Vehicles radiate from their tail funnels oxides of nitrogen, carbon dioxide, sulfur dioxide, carbon monoxide and a complex combination of burnt hydrocarbons and dark residue which pollute the environment. Local sewage and run off from farming fields, weighed down with fertilizers and pesticides contaminate water bodies. Effluents from tanneries contain numerous unsafe chemicals that transmit foul smell. These are just a couple of cases which demonstrate how human activities cause environmental pollution. Pollution may be characterized as expansion of ...

Certain elements involved in the geochemical and biogeochemical cycling are of great concern due to their limited availability both naturally or through industrial manufacture of the compounds involved in the cycles. Some of the processes involved are chemical reactions with other elements or substances. Some of these reactions are irreversible chemical reactions. This implies once the reaction has taken place, the elements are removed from natural cycle and they cannot be replaced again. As such, the more the cases of irreversible reactions, the greater the rate of reduction of these elements from the environment. Ultimately, there could be less ...

Mountain pine beetle (MPB) (Dendroctonus ponderosae Hopkins) is a bark beetle that lays eggs within the vascular system of the mature trees of lodgepole pine (Pinus
contorta). First known epidemic infestation was recorded in 1994 in the forests of British Columbia (BC). Prior to 1994, the infestation was negligible, owing to the fact that extreme low temperatures of winter killed the beetle, thereby curbing the problem. In the past two decades, however, due to global warming the winter temperatures are not low enough to kill the beetle. This has escalated the problem of deforestation and thereby has unbalanced the ...

Abstract

Solid waste and wastewater are primary sources of pollution from food processing industries. The wastewaters usually contain high suspended solids, organic starch and sugars that may contain toxic substances to the environment. Solid wastes come from organic materials while the mechanical preparation processes need biological treatment before releases into the environment. When untreated, they find their way into other water plants like lakes and streams. Since they have higher nutrient content, they result of eutrophication of the water systems hence causing algal growth. It, therefore, compromises the stability of the aquatic ecosystems as the water quality is changed. It ...

As much as it is the responsibility of world leaders to evoke the world of air pollution, they seem to be halted by business magnates who refuse to stop their mega invested projects in a bid to work ...

Human beings depend on air to survive. However, many human beings on many occasions take air for granted. They fail to realize that without the oxygen component of air that human beings breathe in, they would die in a few minutes. By definition, air refers to a mixture of gases that freely roams in the atmosphere. The air circles the earth and is held in place by gravity. The air mixture is comprised of gases such nitrogen, oxygen, carbon dioxide, rare gases like argon and water vapor. These gases are in different proportions with nitrogen having the highest proportion (78%).

Symbiosis is the association between two living organisms such that both parties derive usefulness or benefits from the association. The feature is especially observable between fungi and some trees. The fungi are especially useful in deriving nitrogen from the soil and providing it to the plant. The fungi benefits from the supply of carbon form the plant. Over and above the supply of nitrogenous nutrients, the fungi also provides phosphorus to the roots of the plant. These roots (or rhizae) are the ones that form an association with useful fungi in a symbiotic relationship that results in the formation of ...

THE OMNIVORE’S DILEMMA MISREPRESENTS SCIENCE AND ECONOMY

Introduction
Scientists and economists spend few hours in their beds always thinking of how to feed and ensure safety for the ever increasing world’s population. In his argument however, Michael Pollan is selective of the articles and facts he refers to regarding the way food is preserved, transported, hunted, planted, prepared and consumed. In essence, The Omnivore’s Dilemma: A Natural History of Four Meals presents a view that the present food is not only unhealthy but also carries unethical and immoral philosophies. However, if we were to consider the food issue by referring to the scientific work ...

Toxic substances- This is a chemical substance that is harmful to individual health and the atmosphere at large. They are harmful to humans when inhaled, swallowed or enthralled into the body.

Composting is a process where organic materials in soil are transformed into a dark rich matter referred to as humus or compost (Swartzbaugh, 1993). The process can be biological or could involve using the latest technology to aid in composting. Humus is important in soil as it enhances fertility, workability, drainage, and water retention capacity in soils.
MSW (Municipal Solid Waste) generally referred to as ‘garbage’ is an important source of organic matter to soils when treated through composting procedures. MSW majorly contains waste food, containers and packaging, batteries, old furniture, tires, and oils (Robinson, 1986). However, when introduced directly ...

Eutrophication is the phenomenon caused by the increasing amount of nutrients in the water bodies which results to the decrease in the oxygen concentration and death of aquatic animals. The main nutrient which commonly caused eutrophication in some of the water bodies is the phosphates. In this process, nutrients from soil are carried to the water bodies through erosion (Chislock et al., 2013). The high amounts of nutrients in the water bodies results to the increase in aquatic plants and algae such as the phytoplankton. The decay of these plants and algae converts oxygen to other by-products resulting to ...
