Title: Analysis of Soil Samples for Dispersion and Stability
Abstract:
The aim of this experiment was to analyze and compare different soil samples for dispersion and stability. Three soil samples were tested: mine site soil, tilled soil, and untilled soil. The results showed that the untilled soil sample had the lowest dispersion percentage, indicating stable soil structure. The mine site soil sample had the highest dispersion percentage, suggesting unhealthy soil. Factors such as soil size, density, aggregate, and porosity were found to affect the amount of slaking that occurred. The water in the beaker varied in color, with the mine site soil sample producing cloudy white water due to its properties. Overall, the experiment highlighted the importance of soil structure in determining soil health.
Hypothesis: If the soil sample is compacted and undisturbed, then it will show stable soil structure and low dispersion percentage.
Introduction:
Soil dispersion and stability are important factors in determining soil health and productivity. In this experiment, three different soil samples were tested to assess their dispersion potential and stability. The goal is to determine which soil sample represents healthy soil with stable structure.
Materials:
- Three different soil samples: mine site soil, tilled soil, and untilled soil
- Beakers
- Water
- Measuring devices
- Stirring rod
Methodology:
1. Measure and record the density of each soil sample
2. Submerge each soil sample in water and observe the slaking process
3. Record the dispersion percentage of each soil sample
4. Compare the results and draw conclusions
Results:
- Density of mine site soil: 1.27g/cm³
- Density of tilled soil: 0.97g/cm³
- Dispersion percentage of mine site soil: 12.40%
- Dispersion percentage of tilled soil: 22.22%
- Dispersion percentage of untilled soil: 20.41%
Discussion:
The results of the experiment supported the hypothesis that untilled soil would exhibit stable soil structure with low dispersion percentage. Factors such as soil size, density, aggregate, and porosity all played a role in determining the slaking process. The differences in dispersion percentages between the soil samples indicated their relative health and stability. The water in the beaker varied in color due to the properties of each soil sample. Further research could explore the impact of different soil treatments on dispersion and stability.
Conclusion:
In conclusion, the experiment successfully analyzed and compared different soil samples for dispersion and stability. The results highlighted the importance of soil structure in determining soil health. It was found that untilled soil exhibited stable soil structure, while mine site soil showed signs of instability. Further research is needed to explore the impact of soil treatments on soil health.
Recommendations:
Future research could focus on exploring the impact of different soil treatments and management practices on soil dispersion and stability. It would also be valuable to investigate how these findings can be applied to improve soil health and productivity in agricultural settings. Additionally, further experiments could be conducted to validate the results and expand our understanding of soil structure.
Overall, the experiment provided valuable insights into the factors influencing soil dispersion and stability, contributing to the existing knowledge on soil health and management.
Some questions to ponder when developing your discussion section of your lab report.
- What do you notice/observe about each soil sample?
- What color is the water in the beaker?Why is this?
- What factors affect how much slaking happen?
Which soil sample would represent healthy soil? Why?
- Which soil sample would represent unhealthy soil? Why?
Which soil sample would represent stable soil structure? Why?
Which soil sample would represent stable soil structure? Why?
- What does dispersion percentage of each soil sample infers?
Which soil samples has the highest and the lowest susceptibility potential of dispersion and tunneling why?

It is recommended that laboratory reports are written and submitted using the outline below.
Title
Abstract
Abstracts are a summary of the experiment as a whole and should familiarize the reader with the purpose of the research.Not all lab reports require an abstract However, they are often included in upper-level lab reports and should be studied carefully
When writing an abstract,try to answer these questions:
Why was the research done or experiment was conducted the aim and objectives?
What problem is being addressed?
What results were found?
What are the key findings?
To answer the question above, here are the hints:
Mine soil sample submerged fast less than 2mm followed by tilled soil and untilled soil slow.
Mine soil sample cloudy white, tilled soil sample cloudy and untilled soil sample clear due to their soil property and structure (color)
The factors affecting soil sample are, Soil size, soil density, Soil aggregate and soil porosity.
The healthy Soil sample is a untilled soil sample because it was compacted and not disturbed.
Unhealthy soil sample is mine site soil sample.
Hypothesis
I would suggest using "if and then" statements when developing your hypothesis. There could be more than hypotheses addressing different aspects of the experiments.
