Purpose The purpose of this lab report is to show the difference between the amounts of yields of Maize in Arable Soil and Nonarable soil. It is also to show the affect the Mineral Nitrogen Fertilization has on soil in different weather conditions. Why does NonArable Soil yield more than Arable Soil when using the same amount of Mineral Nitrogen fertilization, except when you use 180kg it yields an equal amount? Introduction When we alter any aspect of soil properties we can influence plant growth and change the production of what is to occur. This can be done in several ways by, the amount of chemicals we use and the climate in which the plant is in. Nitrogen is one of the most important factors affecting soil fertility and productivity as well as the growth and development of cultivated plants. (Barabasz, 2002). Nitrogen fertilizer is key in the growth of any plant.
Hypothesis/Predicted Outcome If you were to use 40kg per 100 acres of Mineral Nitrogen Fertilization, for Arable and Nonarable soil you would not yield the same results.
Methods
We took to of the same plants and planted them in an arable soil and nonarable sandy loam soil. Each plant was given the same amount of mineral nitrogen of 40kg. When given the same amount the yield was notice by a difference of 5.2mg. This show us that the plant that was in the arable soil yield was 13mg, and the plant that was planted in the noarable soil yield was 18.2. Results/Outcome When using the exact amount of Mineral Nitrogen Fertilization the yield is higher for Nonarable soil. The difference is a bout 5.2 mg difference. Discussion/Analysis The reason for this is that the nitrogen provides protein and this is an important molecule of life. As for the arable soil, the natural elements of the soil probably take on the major development the plant and allow it to grow more naturally instead of giving it a boost, as I believe this happens when the nitrogen is used in the no so suitable soil. When you look further into the measurement you will notice that the more you use in the non-arable soil the growth slows down and the arable soil plant tends to eventually catch up and they end up on the same growth level. This is possible by applying adequate amounts of nitrogen fertilizer.

Morton Salt

...Case Study : Morton Salt 1. Briefly describe salt production, from brine production to finished round cans.  Salt is obtained by introducing water into salt caverns which in turn dissolves the salt deposits within the caverns, allowing the salt solution (brine) to be brought to the surface for further processing. The brine is boiled in order to remove most of the liquid, resulting in salt crystal deposits. The salt crystal deposits are then further dried to remove all residual moisture to produce the final product; salt. The finished product is stored within a silo awaiting production.  The round cans used for packaging salt are produced on-site. The cans are produced by gluing two sheets of chip board and rolled into a continuous tube. The tube is then cut into long sections and then cut again into can-size pieces. The finished pieces are moved on conveyor to where the various parts can be assembled into cans and glued. Once the cans are formed, they are filled with salt and the pour spout is added to the can. Once completed, the finished cans containing salt are loaded onto pallets and placed into inventory awaiting shipping to distributors. 2. Briefly describe quality assurance efforts in round can production.  Quality is checked primarily by visual inspection including verifying the assembly was done correctly, checking the filled cans for correct weight, inspecting cans to ensure labels are correctly aligned, and checking to see whether metal pour spouts are......

Essence of Salt

... the main reason for the addition of salt to food was for preservation. Because of the emergence of refrigeration and other methods of food preservation, the need for salt as a preservative has decreased, but sodium levels, especially in processed foods, remain high. The expected tastes and flavors associated to salt use is enormous coupled with the relative low cost of enhancing the palatability of processed foods, thus making it a key rationale for salt use in food preservation. However, taste is not the only reason for the continued use of high levels of salt in foods. For some foods, sodium still plays a role in reducing the growth of pathogens and organisms that spoil products and reduce their shelf life. In other applications, sodium levels remain high because salt plays additional functional roles, such as improving texture. A number of other sodium-containing compounds are also used for increasing the safety and shelf life of foods or creating physical properties. This work begins with a review of the non-taste or flavor-related roles of salt and other sodium-containing compounds in food. The second part will briefly discuss the role that sodium plays in various food categories and provides examples of the sodium content of various foods. ------------------------------------------------- FOOD SAFETY AND PRESERVATION ------------------------------------------------- As mentioned previously, the first major addition of salt to food was for taste and to prevent......

Salt and Water Volume

...Connection Between Salt and Water Volume and in Blood Pressure Changes Salt (sodium) is essential to our bodies. Normally the kidneys control the level of salt. If there is too much salt, the kidneys pass it into urine. But when our salt intake levels are very high, the kidneys cannot keep up and the salt ends up in our bloodstream. Salt attracts water. When there is too much salt in the blood, the salt draws more water into the blood. More water increases the volume of blood which raises blood pressure. Some people are more sensitive to salt than others. In some people too much salt will cause their blood pressures to rise, in others there will not be as large a change. About half of people are salt sensitive. African-Americans, the elderly and people with diabetes are more often salt sensitive. If you have high blood pressure, you can always benefits from decreasing your salt intake. Sodium has an important influence on blood pressure, but we are not sure exactly how it works. Since the systems that control blood pressure include dozens of complex vascular, neurological, and hormonal elements. Although the body can rid itself of excessive dietary sodium, it seems likely that eating salt expands your blood volume, at least to a subtle degree. In turn, the extra volume may signal your kidneys to trigger a cascade of hormonal and vascular effects that raise blood pressure. And some experts suspect that these hormones may have adverse effects on vascular health even if blood......

The End of Salt... or Not

...The end of Salt… or Not There were many aspects to our class that I found interested and engaging, even for one who has never been fond of history education. For so many years I have never been able to appreciate the founding of historical beings, artifacts, traditions, and even religion. I did enjoy our text that we were given this year; it was easy to read, didn’t bore me, gave illustrations that were factual but also entertaining, and also intrigued my mind. So many things in our age we take advantage of, we have no idea where things originated from, and in all honesty may be the wrong direction in which most of our generation and future generation are choosing to go in. Salt for example, I would have never thought to be such a significant mineral, or asset to a particular era or development of. I first have to address the way in which the author of our salt reading wrote. She was funny, educational, and I would think appealing to most readers. Maybe to some it seemed insignificant but to me it made me begin to look at the littlest of things and wonder where, when, and why did it originate. Salt was the beginning of something huge for this time. As we learned it was the most common commodity used in its times. As I spoke about in my first journal entry, the Egyptians using Nortran to preserve those that passed bodies, they also used it for fresh food so that it would not spoil.  Most importantly while reading I began to see how the importance of trade became....

Bath Salts

... Pete March 16, 2014 Quickly Emerging Impacts of Bath Salts The first thought that comes to mind when I hear the term bath salts is the actual crystalline substance that is placed in bath water and simply dissolves in order to perfume, or soften the bath water. In today’s society the use of bath salts is much more that. This new trending substance began to take on an emerging effect in the U.S. and Europe populations at the end of the last decade. Synthetic cathinones are usually in the form of a white or brown crystalline powder that comes packaged in plastic or foil. “Not for human consumption” is the most common label that can be found on the outside of the package, but others may be labeled as “plant food,” “jewelry cleaner,” or “phone screen cleaner.” The pathological impacts and psychological impacts of this newly emerging drug are very closely related in the way that some of the effects could be caused psychologically and pathologically. In regards to pathological impacts it is referring to the effects on how this synthetic drug affects the user. the Specific impacts the individual could experience be rapid heart palpitations, chest pains, sexual stimulation, excessive energy, nausea, and elevated blood pressure. In more extreme cases, reporters have indicated intense aggressiveness and psychotic behavior with amplified psychical force. Just like the pathological effects, the psychological effects of bath salts also vary from a large list. Psychological effects are......

Salt Intake and Risk of Heasrt Disease

...Biology-draft Salt intake and risk of heart disease Sodium is the major positive ion in fluid outside of cells. The chemical notation for sodium is Na+. When combined with chloride, the resulting substance is table salt. Excess sodium (such as that obtained from dietary sources) is excreted in the urine. Sodium regulates the total amount of water in the body and the transmission of sodium into and out of individual cells also plays a role in critical body functions. Many processes in the body, especially in the brain, nervous system, and muscles, require electrical signals for communication. The movement of sodium is critical in generation of these electrical signals. Sodium as an electrolyte is important for the human body. But Too much or too little sodium therefore can cause cells to malfunction, and extremes in the blood sodium levels (too much or too little) can be fatal. Too much of sodium This report will investigate the possibilities of a person acquiring a heart disease due to sodium content in his diet. What are some of the possible complications of hypertension? What organs of the body are involved in the hypertensive individual? These are the questions that will be answered here. The heart is affected by hypertension because it has to work harder to pump blood. If hypertension is left untreated, it may lead to heart disease. Increased pressure in the kidneys destroys their tiny arteries. If damaged, the kidneys may not be able to do their job of......

Salt March in India

...The Salt March, also known as the Salt Satyagraha, began with the Dandi March on March 12, 1930, and was an important part of the Indian independence movement. It was a direct actioncampaign of tax resistance and nonviolent protest against the British salt monopoly in colonial India, and triggered the wider Civil Disobedience Movement. This was the most significant organized challenge to British authority since the Non-cooperation movement of 1920–22, and directly followed the Purna Swaraj declaration of independence by the Indian National Congresson January 26, 1930. Mohandas Karamchand Gandhi (commonly called Mahatma Gandhi) led the Dandi march from his base, Sabarmati Ashram near Ahmedabad, to the sea coast near the village of Dandi. As he continued on this 23 day, 240 mile (390 km) march to produce salt without paying the tax, growing numbers of Indians joined him along the way. When Gandhi broke the salt laws at 6:30 am on April 6, 1930, it sparked large scale acts of civil disobedienceagainst the British Raj salt laws by millions of Indians. The campaign had a significant effect on changing world and British attitudes toward Indian independence and caused large numbers of Indians to join the fight for the first time. After making salt at Dandi, Gandhi continued southward along the coast, producing salt and addressing meetings on the way. His group planned to stage a satyagraha at the Dharasana Salt Works, 25 miles south of Dandi. However, Gandhi was arrested on the......

(Wurstsbaugh, 2014, d) Abiotic Components -Surface elevation 4200 feet above sea level -Depth averages 14 feet -Railroad crosses through the lake -Averages 15.7 inches of precipitation per year -Water temperature varies from below freezing to 80 degrees Fahrenheit. (Gwynn, 2002) Current Human Impact -Humans building a railway through The Great Salt Lake has divided the lake and caused that half of the lake has a higher salinity percentage than the other half. This is caused by the South end has more fresh water flowing into it and the North end has more salt water flowing through it. Because of the railway, it doesn’t pass through to the other side. The percentage of salinity is affecting the brine shrimp eggs harvest. It has decreased. The residents in the Salt Lake area use more water than the average people in the country.

Great Salt Lake Ecosystem

...Great Salt Lake Ecosystem The Great Salt Lake is the remnant of Lake Bonneville that covered much of Western Utah and parts of Nevada and Idaho during the Pleistocene Era. It is a terminal lake, three and a half to eight times saltier than the oceans, which supports brine shrimp and flies along with algae and bacteria that have adapted specially to this extreme environment. It has three contributing rivers that flow into it, the Bear, Provo/Jordan, and the Weber. There are no fish that can survive in the lake, but it has become a resting ground for some two to five million migratory birds making it an important bird refuge (United States Geological Survey, 2013). Although the saltiness and general lack of organisms would make the Lake to appear as simple it is a fragile, complex ecosystem. Structural and Functional Dynamics of Great Salt Lake The structure of the Great Salt Lake lends to very dramatic changes in the size and volume of the lake with even small changes in water amounts. The Lake only averages 14-16 feet in depth with the deepest part around 34 feet, and an elevation of 4200 feet above sea level. At its lowest point of 4191.35 in 1963, or just eight feet lower than its historic average, the Lake saw a decrease of surface area from 1700 square miles to 950 square miles (United States Geological Survey, 2013). With just an increase of 11.6 feet of elevation the surface area jumped to more than 3300 square miles. The Lake serves the millions of......

Salt

...Salt What is it exactly? Salt is the residual left when waters from ancient oceans evaporated in shallow seas or marginal basins. http://www.waterencyclopedia.com/Mi-Oc/Mineral-Resources-from-the-Ocean.html Where is it found or used geographically? It is found in salt mines or in shallow water that is mineral rich. http://en.wikipedia.org/wiki/Salt How is/was it used? Salt is used in many different ways. Salt is used in the seasoning or flavoring of food while it also can be used to preserve it. People use salt to put on road during icy weather to keep traction on the roads so people do not slide while driving. Instead of using harsh chemical around your house to clean with salt is another option that can be used. Many people think salt is bad for your health while in fact it can help your body when using it right. A common example is gargling salt water when having a sore throat as long as you spit it out and not drink it. http://impossible2possible.com/bolivia/thickboxes/salt_uses.php http://en.wikipedia.org/wiki/Salt Who discovered it? There is not a specific person that can be named for the discovery of salt. But evidence has found early evidence of its use. The earliest one date back to about 8,000 years ago. People from Romania were boiling spring water to extract the salt that was in it, also saltworks in China have been found that date around the same time. http://en.wikipedia.org/wiki/Salt Why is it needed/used?

Salt

...Salt Is More Than a Four-Letter Word On today’s Words and Their Stories we talk about a common word, a small word, but a word that is completely necessary for human life. In fact, without this simple, everyday material, all humans would die. Scientists know it as sodium chloride. We know it as salt. You may think, salt is just a simple cooking element we shake on our food for a little extra taste. But salt is much more than that. Without salt our muscles would not move. Our nervous systems would not operate. Our hearts would not beat. Salt means life. But do not think rubbing salt in a wound will help. Doing that would be painful and not heal the wound. To rub salt in a wound is an idiom that means to purposefully make a bad situation worse. Early humans got the salt they needed to stay alive from the animals they killed. But advances in agriculture led to a diet low in salt. So, humans needed to find others sources. Those who lived near the ocean or other natural sources for salt were lucky. Those who did not had to trade for salt. In fact, people used salt as a method of payment in many parts of the ancient world. The word “salary” comes from the word “salt.” Salt also played an important part in population movement and world exploration. Explorers understood that if they could keep food fresh, they could travel longer distances. So they used salt to preserve food and explored the world. Salt meant......

Observation

...OBSERVATION: During the winter, you spread salt daily on your driveway to melt the snow. In the springtime, when the lawn begins to grow, you notice that there is no grass growing for about three inches from the driveway. Furthermore, the grass seems to be growing more slowly up to about one foot from the driveway. QUESTION: I wonder if the grass growth is inhibited by salt? INTRODUCTION: Salt is a chemical compound (NaCl), or Sodium Chloride. Sodium Chloride has many uses in everyday life, such as in our bodies, in our food, and on our road ways. Having two elements, Sodium and Chloride, each have a number of jobs to do in our bodies. Salt is found in many of our foods naturally, from fish to vegetables, as well as being used for cooking and at the table. Also salt is used all over the world when it snows to prevent slip and falls and car accidents by it being sprinkled on sidewalks and road ways to melt the ice. When salt hits water or ice it lowers the freezing point in an effect known as freezing point depression and melting it in the process. According to (greenergreengrass.com) salt can also affect the pH of soil and can create an unsuitable environment for grass and plants to grow. HYPOTHESIS: The grass that gets exposed to more salt will not grow as much as the grass that gets exposed to little or no salt. PREDICTION: If the grass is exposed to salt then it will not grow as fast as the grass that is not exposed to salt at all. CONTROLLED EXPERIMENTAL......

...Magic Salt, Melting Snow. On this experiment, it’ shows how will acquire some basic and some practical information on the chemistry and physics of water, it’s melting a freezing points and how various differing chemical compounds are utilized to promote a change of state. For example, just plain salt can be used to raise the melting point of water or lower the freezing point. Salt lowers the temperature at which water freezes. Salt absorbs moisture and forms ions when dissolved in water. In the case of snow or ice, when salt lowers the melting or freezing point of water, it serves as a freezing point depressor. Other substances that dissolve in water also lower the freezing point of the solution. The amount by which the freezing point is lowered depends only on the number of molecules dissolved, not on their chemical nature. This so called freezing point depression is described as a colligative property of water. This property is one that depends on the number of ions that a substance produces when placed in solution. The more ions a substance produces when in solution in water, the more effective it is in lowering the freezing point of water. Salts such as sodium chloride and calcium chloride which ionize are useful in de-icing. However there are other variables to be considered such as the effects of these salts on grass, pavements, cars, concrete and living animals in the area. As for the methodology of this project, this science fair experiment also serves to......
