Practice exam question

I remember that mineral matter is a better conductor comparing with organic matter. However, SOM has large number of negative charges and high water retention. Why isn't this the other way around?

Becca, we will cover thermal properties of soils after the midterm exam. IF you are referring to hydraulic conductivity consider that hydraulic conductivity is maximum in saturated conditions, and that when a soil is saturated, large well connected pores are better conductors of water than small pores.
