Soil pH

sampling in determining soil nutrient levels. Soil samples collected from Flinders Campus were used to determine their pH, salinity, ammonium, nitrate, phosphate, and nitrite levels. Introduction Unless there is a specific problem 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…

nitrogen oxides also comes from volcanoes and biological decay. Winds spread these acidic arrangements across the atmosphere and over many miles. At a point where acid rain reaches Earth, it it seeps into the soil and the…

with an acidic pH level are taken out of the atmosphere through precipitation. When we pollute the air by burning fossil fuels, we create different chemicals that end up in our atmosphere. A few of these have chemical reactions with the water in clouds, and form (depending on the chemical) sulfurous and nitrous acids. When it rains, this acid is taken back to the ground. While pure water has a neutral pH level of 7, even unpolluted water will have an acidic pH level of 5.6 due to CO2, NO,…

hazardous wastes into river, ocean, and soil has resulted in a dramatic change in pH of the non-renewable resources and leads to a destruction in the ecosystem. Specially in agriculture, crops cannot grow in acidic soil, so it is crucial to maintain the acidity of the soil at a neutral state. Consequently, farmers use lime fertilizers such as powdered limestone, CaO, or the ashes of burnt wood to neutralize the acid in the soil. However, considering that the change in acids…

question: What is the effect of changing the pH of the soil on the germination and growth of mustard peas? Hypothesis: The greatest number of peas will germinate and will grow the most when the pH is 5 or 7. Theory: Enzymes play a vital role in the cells of plants (especially when growing) and enzymes work best when at their optimum pH value. Moreover, all chemical reactions have an optimum pH at which they work best (Howard and Loomis, no date). Generally the enzymes in plants work best…

Green plants are multicellular, autotrophic eukaryotes. They use their roots to absorb nutrients and water from the soil. “Fast Plants are a type of crucifer (a large group of plants that includes mustard, radish, cabbage, and more) that have been bred and selected to have a uniform, short flowering time (14 days) and grow well under in a small indoor space, with little soil, under artificial lights”(The Story of Fast Plants). Wisconsin fast plant are plants that grow at a very high speed rate.…

The experiment about pH brace our hypothesis because the pH of the enzyme amylase is 7. It has correlation because human beings have pH of 7 as well. The pH of 7 is known as neutral. This means that the concentration of H+(hydrogen) ions and OH- (hydroxide) ions is 10⁻⁷. For example, saliva is an enzyme amylase in the human body. It needs to have a pH of 7 will not denature because it is neutral. Therefore, the amylase will be effective. Also, it has adapted to the pH, so it can breakdown the…

The purpose of this laboratory experiment was to create a clear aqueous fertilizer that had a pH range of 6.0-7.0 with first three solid compounds the first day and then four solid compounds the second day. To complete this experiment, make calculations to find how much of each compound is needed in grams, use an analytical balance to measure out compounds accurately, mix the compounds in DI water until they are dissolved, test pH levels, effectively add acids or bases depending on pH level, and…

acidic in which the pH was about 5.6 and is considered problematic when it is less than this pH (Botkin & Keller, 2014; ESA, 2000; Kulp, 1990). In other words, acid rain is precipitation with pH below 5.6 (Botkin & Keller, 2014). Pre-industrial, the rain was slightly acidic because it reacted with atmospheric carbon dioxide (CO2) and water (H20) in the atmosphere to form carbonic acid (Dubey, 2013). Below is a general formula representing the reaction of CO2 and H20 to form carbonic acid: H2O(l)…

The Effect of pH levels on the Motility of Daphnia in Lake Ecosystems Introduction: The production, transportation, and use of chemicals by chemical industries can result in chemical pollution. This leads to a harmful effect on ecosystems and their balance of life (Linlin, Chen, 2012). The pH levels of aquatic environments are important because it affects the physiology of animals by changing their behaviors. The ion concentrations associated with the water and the organism’s survival can also…
