Midterm #2

Fragment of a discussion from Course talk:APBI200

Hello Sandra,

I was wondering how much of the Soil Biology unit will be tested on Midterm 2? Will we be asked about the specific characteristics of each type of organism or just understand their overall roles in the soil?

Also, in regards to Problem Set #2, what kind of material might we be tested on? You mentioned in class that there would not be a calculator question. So will we be tested on the different potential calculations? Or should our focus be more towards Pore Size Distributions, Soil Acidity, and Soil Salinity?

Thank you.

Hi Anika

re: soil biology you should know major groups of organisms and their role in soil & some key organisms within each group. For example, macro-organisms - what are some example organisms that are important in soils, and what do they do (in soils).

re: problem set #2 - focus on the parts which relate to soil chemistry. As indicated in an earlier post, midterm #2 will concentrate on material related to soil chemistry and soil biology - thus you will not be asked a specific soil physics question such as using soil water potential to determine the direction of flow; BUT you do need to understand how texture, soil water retention etc. related to overall soil quality assessment (similar to question 6 on the in-class review where you compared characteristics of 3 soils).
