  • Determining Soil Nutrient Levels

    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…

  • The Importance Of Nutrients In Plants

    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…

  • Earthworms Lab

    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 movement,…

  • Plant Science Seed Germination Lab Hypothesis

    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…

  • Calcium Levels And Species Richness Hypothesis

    Kishan Patel Section: 008 Pattern: Calcium 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…

  • Analysis Of Lulu Island Marsh

    that data taken from sample sites at the marsh such as pH, amount of organic matter deposited within the soil, and amounts of specific sediments deposited within the soil has a linear pattern as the marsh extends to the shore. This report will examine elevation, soil pH, water salinity, and soil texture data from unbiased sample sites in hopes of finding a relationship to support the hypothesis of this…

  • Blackmore Series Essay

    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 of approximately 0-15% and…

  • Nitrate And Phosphate Level Lab Report

    through my data relates to my hypothesis since it proves that the epigeic earthworms in the soil increased the nutrients in the soil, since the average nitrate and phosphate levels increased from tests 1-3. The results from this experiment showed that the control group increased their phosphate levels more so than the experimental groups, which contained the red wriggler earthworms. This could have been due to high amounts of Ca²⁺ in the water, leading to the Phosphate binding to Calcium, which…

  • Composting Research Paper

    resources, while helping improve plant development. Though compost provides the necessary nutrients for plants, some are concerned about the cost of composting. According to the “Green Action Centre,” compost is very cost effective and helps save money. This persuades gardeners from using harsh chemical fertilizers. Due to composting having the ability to decrease the amount of kitchen and garden waste, this reduces the needs for fertilizer, also making it cheaper to garden. Anything from…
