Hi. I'm doing a research about the composting operation. Your suggestion would be really helpful. Thanks a lot. 1) Is there a simple proportion between C and N in mixing the compost? For now we mix them as 1:1. But if I want to reduce the Carbon what's the minimum portion I could do. 2) Is there a general number for the density of the compost? What I'm using now is the density of a good quality soil.
