Soil Analysis Lab

We set up 3 fermentation set-ups, labeling them 1, 2, and 3. Then, filled a tub with hot water and inserted the end of the plastic tubing into one of the test tubes and submerged the collection tube and plastic tubing in the tub. After that, we mixed the fermentation solutions for the other tubes, (tube 1 got 4mL of water and 3mL of corn syrup, tube 2 got 3 mL of water, 1 mL of yeast and 3 mL corn syrup, tube 3 got 1 mL water, 3 mL yeast and 3 mL of corn syrup) . We then mixed each test tube and put the rubber stoppers in the fermentation tubes. Finally, we marked the water level on each collection tube with a wax pencil to use as the baseline. Then at 5 minute intervals we measured the distance from the baseline for 20 minutes.

We will take 3 measurements of how deep the soil is in 3 different places to get an overall average.

Measure 500ml of tap water in the 500cm3 beaker, then measure 5g of sodium hydrogen carbonate using the 50cm3 beaker and weight scale and place in the beaker of water, using the glass rod to dissolve it into the mixture.

To calculate the effective diameter of the particles, we use Equation 1 provided below. To determine the effective diameter of the particles, we needed to have the hydrometer readings and temperature for each time taken, as well as using the Coefficient of temperature adjustment table provided in Appendix 3 and the Hydrometer 152H length readings in Appendix 4. To able to determine the Percent Finer for Hydrometer, we use Equation 2 provided below as well as Equation 3 for the Dry Weight of Soil provided below. For Equation 2, we also need the Specific Gravity correction for percent finer table to be able to solve Equation 2. The Specific Gravity correction for percent finer table is provided in Appendix 5. Furthermore, to determine the total

“Drainage patterns, the hilliness of the ground, the range of soils, the nature of the bedrock,

Add RO water to the 25 ml volumetric flask up to the mark. Put stopper on the flask and shake it properly.

6.) Measure out 50ml of water from the wetland. Place filter paper in a cone shape into the glass funnel then place the funnel above an empty beaker and then pour the 50ml and the see for any precipitate, insects and dirt then record results.

The soil has a thick litter layer, but thin humus layers due to fast decomposition. There is also a rapid leaking, which is the downward movement of the nutrients in solution in the soil. Soil is determined by the climate, vegetation, topographic position and soil age.

Repeat steps 3-4: Fill 1 tube with 50% NaCl. Weigh each of the tubes/cells. Record on the chart. 3. Label a 500mL beaker with 50% NaCl and fill it with 400mL of the 50% NaCl solution.

Submerge the graduated cylinder in the plastic tub so that it is completely filled with water. Hold the open end of the graduated cylinder and move it vertically upside-down where the open end of the graduated cylinder is still submerged in the plastic tub. Clamp the graduated cylinder the ring stand of the lab table to keep it in place. perforate a hole in the top of the rubber cork for the solution container. Cut a straw the length of about four inches. place the straw inside of the rubber cork hole. Set up your timer for two minutes.

Trial Pitting – Trial pits can easily be performed by hand but it will take triple the amount of time and you won’t be able to get a good depth to get a good samples. Trial pits are usually dug mechanically because it is finished much faster and can be dug a lot deeper. Trial pits are normally excavated at 4.5m deep as this provides a good insight of what the foundations will be sitting on and it provides information if deeper foundations are needed. The advantages of machinery is that greater depths can be achieved which would result in a more detailed soil sample test etc. A disadvantage of this would be minor ground disturbance which could cause problems.

1. A representative sample was chosen by quartering (according to BS 812: Part 102: 1984) or by use of a sample splitter (Fig. 2C1-3). The sample to be tested should be the approximate weight desired when dry. For this experiment, about 3 kilograms of coarse aggregate was weighed.

Wetland soils are extremely varied. They are found from the tropics to the subarctic. They can be seasonal or year-round, freshwater or saltwater, organic or mineral. The one thing that all of them have in common is that for at least part of the year they are saturated with water. This saturation has a significant impact on the soil's physics, chemistry, and biota. However, over the past century more than half of all the wetlands in the United States has been drained for agriculture and other uses such as construction. When the soils are drained the physics, chemistry, and biota are drastically changed. This paper is an attempt to

Approximately 2000g of a soil sample that passed a No. 4 sieve was measured. Calculations were done for how much water should be added to reach the desired moisture content. The calculated moisture was added with a spray bottle and mixed thoroughly in the sample. The sample was then placed in a cover container. These steps were done prior to the experiment.

Expansive soils have been reported from many parts of the world, mainly in the arid or semi-arid regions of the tropical and temperate zones like Africa, Australia, India, South America, United States, and some regions in Canada. This never means that expansive soils do not exist elsewhere, because they can be found almost everywhere. However, in the humid regions water tables are generally at shallow depth and moisture changes, which are responsible for volume changes in soils, are minimal excepting under extended drought conditions (Arnold, 1984; Shuai and Fredlund, 1998; Wayne et al. 1984).
