  • Tutorial practice questions mentioned in the "Virtual Soil Monolith Collection" cannot be accessed at that website, so they are posted here Practice questions

Lab 3 Assignment

Lab assignment - Texture and bulk density
Pls read the manual. Introduction for each lab includes all the information needed to answer lab assignment questions.

Pls attach the following to your lab assignment:
•Your hydrometer data sheet with sample calculations written out for at least one line in the data collection table (ie one time of measurement).

•The particle-size distribution curve. Don’t forget to include a title and axes labels. Indicate the % sand, silt and clay and the soil textural class.

•The table regarding the soil texture of two “mystery” samples (determined by hand-texturing). Include a brief justification of your answer.

•Calculation for sample used for demonstration of bulk density determination by core method.


Semi log paper (needed to draw the particle-size distribution curve) can be found in the attached pdf file. Bonus mark if you plot the data in Excel (but pls remember to use semi-log scale). Semi-log graph paper

Lab 4 Assignment

Lab assignment - Water retention

Required attachments for lab assignment:
•Your data collection sheet with calculations written out for both samples parameters (lines a through k), and for the first 2 tension values. Be sure to include units when you enter your data and to keep track of units when making your calculations.

•The water retention curves for medium and fine sand samples indicating air entry value (AEV) and air intrusion value (AIV). Use your data that you collected in the lab and also data provided in the appendix A (on p.92) of the lab manual.
