At your lab bench you will have 3 different soil texture classes (soils A, B, C) arranged in a funnel that has been prepared with a filter at the bottom. You will add a designated amount of water (50 mL) to each of the soil samples and record the time it takes before you see water move through the other end. After 2 minutes has passed you will also measure the amount of water that flowed through the soil into the catchment beaker. Record all observations below and answer the following questions:
SOIL A \(\rightarrow\) | Time = | Volume water that flowed through = |
SOIL B \(\rightarrow\) | Time = | Volume water that flowed through = |
SOIL C \(\rightarrow\) | Time = | Volume water that flowed through = |
- Out of the following textures below, please indicate which was SOIL A, B, or C.
- Sand =
- Silty Clay Loam =
- Clay =
- Which texture class did the water move through the fastest? The slowest?
- Why do you think this occurred?
- What is a practical application of this method? (Aka why would you want to know this specific information about the soil?)
