Soil pH

and encroachment. Degradation can also range from nutrient depletion, changes in soil structure and PH, desertification, and loss of organic matter (Brennan, 2005). The beautiful land in many parts of Arundel has become very over grazed. This is the main cause of the land degradation. Over grazing can lead to soil erosion and deposition, land degradation, and the overabundance of weed take over. Additionally, soil loses can lose it’s nutrients and organic matter. Overgrazing…

1.INTRODUCTION Climate change has become one of the leading factors that has damaged rural communities in the developing world. Rural areas in the developing world are mostly affected by climate change due to lack of education and funds to implement measures that can curb climate change. Climate change has damaged rural communities by affecting the livelihood of the rural people, health, agriculture, the economy just to mention a few. Natural disasters, sea level rises and global warming are…

P. putida and P. fluorescens isolates were cultured in 250 ml Laurea Broth (LB) medium at 30±1 ºC for 36 h in an incubator shaker at 150 rpm. The culture was then poured into 50 ml falcon tubes and centrifuged for 10 min. at 6000 ×g at 4 ºC. The pellet was washed thrice in 15 ml distilled water and centrifuged. Then it was dissolved in distilled water and the optical density (O.D) of the culture was set at position-1 at 600 nm=107–108 colony forming units (CFU) ml-1 for inoculation (Bhuvaneswari…

The values that arise from the feed analysis were: the dry matter, crude protein, acid detergent fibre, neutral detergent fibre, pH level and ash. Specifically, the value for the dry matter is the corrected value in order to allow for acids, volatile acids and other components that lost on oven drying. The crude protein which is determined from the total nitrogen of silage is 88.33 (g/kg DM). The value of the acid detergent fibre which is a measurement of lingin, cellulose and lignified nitrogen…

Acid, below-normal pH, causes many problems in our world today—from drinks to teeth, from pollution of industry to natural disasters. Acid is a chemical substance that can subdue alkalis, can dissolve specific metals and can turn them into salt, such as calcium, turns red on blue litmus paper, is corrosive or sour-tasting when it comes to liquid, generates pain in wounds, and turns colorless when placed in phenolphthalein which is used as a basic to acid indicator ("Definition of acid in…

Water Quality Water is essential to human life and the health of the environment. Good water quality is essential for irrigation, drinking and recreation and also sustains ecological processes that support native fish populations, vegetation and bird life. We expect that our water supply will not only be safe, but will taste good, and look crystal clear. Water quality is commonly defined by its physical, chemical, biological and aesthetic (appearance and smell) characteristics. Water quality…

Communication /6 Problem #2 Use the chart you just created to answer the following questions. a) Which substance would be the most corrosive? /1 Sample number 2 is the most basic and corrosive substance between the four samples. With its very high pH of 12, it can be predicted that sample number 2 is the oven cleaner that contains Sodium Hydroxide. Sodium Hydroxide (NaOH) is highly corrosive due to its elements; the presence of oxygen and an electrolyte (Sodium – Na) cause corrosion, the…

The purpose of this experiment is to determine the pH of known substances by use of a pH color indicator of red cabbage and the use of a pH meter. As well as, to observe the pH changes in a substance by adding in more basic of acidic to buffered solutions and unbuffered solutions. This experiment will also will show how to calculate H3O+, OH- and pH by use of known values. In order to do this lab, there are a few key components one needs to know and understand first. A solution is a homogeneous…

thing to humans than anything else. It is important to take care of the body from any harm. One thing that the body is capable of is maintaining pH levels and buffers. A pH is the power of hydrogen and buffers prevent extreme shifts in pH. The blood has a specific type of buffer that is maintained at pH level of 7.4. If the buffers shifts and levels of pH go to 7 or 7.8, it can be deadly. The blood buffer contains carbonic acid which dissociates into bicarbonate acid and hydrogen ions. This…

nZVI conc. (0.20 g/L) and initial pH of the conical flask was measured. The pH of the dye solutions were adjusted with dilute HCl (0.1N) or KOH (0.1N) solution by using a pHmeter with pH of solutions being 2,4, 6,8, 10,12 .The adsorption of MR dye on nZVI was studied in a pH range of 2–12. Methyl red is slightly acidic pH ranges from 4.5- 6.5. Fig. 4.3 shows the obtained results. The figure indicates that, for MR, the adsorption is strong in acidic medium. As the pH increase, the adsorption…
