Wood chip question 2
Fragment of a discussion from Course talk:APBI200
Becca, consider thermal diffusivity in relation to subsurface temperature changes; thermal admittance relates to surface temperature changes.
1st be clear that in this question there is an organic layer (wood chips) overlying the mineral soil. The question (#4) asks how the organic layer on top of the mineral soil will impact the temperature of the mineral soil (in winter). Consider whether or not, the "heat" lost from the mineral soil in winter will be less, the same or greater with an organic mulch on top; and why?
