Soil pH

Introduction: Within this task we were required to determine the ecological state of the Reddam House wetland, which I presume is at a good standard. I decided to test the ecological status of the wetland by gathering samples from the wetland and testing it for various aspects in the water and the plants that are found within the area. Method: • Collected water in a sterilized bottle at Reddam House wetland as well as observed surrounding fauna and flora. • Took the water to Rand Water to have…

levels in the soil controls soil pH and species richness within a community Hypothesis 1: Calcium levels in the soil controls soil pH. Prediction: An increase in the calcium levels in the soil will make the soil less acidic. Reasoning: Calcium exists mainly in the soil as exchangeable cations (ca^2+) associated with basic anions, which reacts with soil acidity (H) to neutralize it. Analytical approach: Regression Independent variable: Calcium levels Dependent variable: Soil pH Hypothesis…

Johnson 125). The researchers discovered that when the synthesized acid rain reached pH levels below 2.0, there were significant reductions in the germination of such plants (McColl and Johnson 127). Additionally, some of the germination rates in certain firs and pines were reduced by up to 32 percent (McColl and Johnson 125). Also, there were related problems to the plants that were exposed to the acid rain with pH levels below 2.0. The plants appeared to have problems absorbing and utilizing…

detailed description of soil locations, textures and physio-chemical properties can be found in Sections 2.3.1(page 41) and 3.3.1(page 56). We selected four types of soils out of seven types of soils, namely MGA, KBA, TAA and DUA. Key soil characterisation of these four soils is summarised in Table 4.2. The reason why these four types of soils were chosen for this chapter was that they had distinct soil parameters in terms of total organic carbon (TOC), Fe oxide, Al oxide, pH which have been…

Temperature is one of the water characteristic or more precisely one of the physical water parameters. Water temperature affects almost all other water quality parameters. It plays a key role in aquatic life and habitations. Thus, the fluctuation of temperature controls what aquatic kind will live and bloom in the water body. Water temperature can also affect “the metabolic rates and biological activity of aquatic organisms”. Therefore metabolic rates of aquatic organisms is directly…

pH Levels: The pH level system is the measure of the concentration of hydrogen ions in solutions. Subsequently, if there is a higher concentration then the pH is low meaning it’s acidic and if there’s a lower concentration then there’s a high pH levels meaning it’s basic. pH levels affect the quality of water because it affects the toxicity and the solubility of chemical substances and heavy metals. This causes the concentration of hydrogen ions in the water to change from the normal pH range…

salinity level should be between 0.5 to 35 ppt. The typical pH range for an estuarine system is between 5 and 9, which is the range most finfish populations adapt to live in (pH, 2012). The main chemical species responsible for affecting the pH include the levels of oxygen and carbon dioxide (pH, 2012).…

in population. The quality of soil is of paramount importance when it comes to planting crops. A major factor attributed to soil quality is the presence of earthworms. Earthworms are very important in the world of agriculture and can help maximize crop yields. In this study, the effects of earthworms on varying soil pHs and soil density were viewed. Earthworms (Lumbricus terrestris) are very beneficial for the soil. They change the structure and composition of the soil, they alter water…

Argiustolls which is of the Mollisol order (National Cooperative Soil Survey 2000). It is found only within the Gallatin County of southwest Montana. Blackmore soils are not very prevalent within southwestern Montana. The exact location of the Blackmore soil type is found specifically 1100 feet south and 1800 feet west of the northeast corner of section 27, T. 2S., R.6E. This area has an elevation of 4,800 to 5,500 feet. This type of soil can be found on relict stream terraces with slopes…

2.1 Soil The soil is a major source and natural medium for plant growth which has a direct impact on yield and quality of crops growing on it. 2.1.1 Nutrients in soil Most plants raise by absorbing nutrients from the soil. Soil is a major source of nutrients needed by plants for growth and development. There are two main classification of nutrients in the soil; Macronutrients and Micronutrients. Carbon (C), Hydrogen (H), and Oxygen (O) are also essential for plant growth, but not considered…
