I'm late on my wake n bake today. Been doing math shit again. Worse than the rain. Here guys, give this a shot if you feel so inclined.

1. You are given 100 kg of ground corn stalk residue (C/N = 80:1) to add to your garden. You can assume that the residue is 50% C and that 70% of the C will be converted to CO2 during the decay process. Assume that the C/N ratio of microbial biomass is 7.5:1. Answer the following questions. Show all calculations.


A. How many kg of C have you added to the soil?



B. How many kg C are released as CO2?


C. How many kg of N have you added to the soil?


D. How many kg of N will be needed to completely convert the residue to new microbial biomass?


E. How many kg of N will be mineralized/immobilized?

LOL. Good luck.
I don't know how to to answer all of the questions but maybe I'll be close enough!

A. 50kg
B. 35kg
C. 0.625kg
D. 7.5kg
E. I don't know if I have enough info to answer
 
The cardinals are back . :biggrin: Their very shy here and have lots of trees to hide in and their very sharp and avoid the prying eyes of the amateur photographers . By the time I get my camera focused they move on and whistle at me as they pass by . :rofl: :finger:
