[USCC] ammonia

[gregory th stamler]

Good day.I am in charge of monitoring our aerated/in bag composting of 
fish offal combined with wood shavings. After a day of starting the 
air, the temp. gets to 60 C and a vapor cloud with a strong ammonia 
smell starts coming out of the open toped bag.
I have two questions: Is the nitrogen  portion of the mix too high 
(which I think is)  and should I cover the top of the bag more to 
condense the vapor back into the bag and make the ammonia available to 
the critters doing the work !!
As always your thoughts and questions are welcome. Thanks, Greg at 
Meeker Aquaculture.
