Calculating the Composting Carbon Nitrogen Ratio
How do you apply the carbon-nitrogen ratio if the compost consists of more than 1 C:N (greens and browns) ratio? For example, I want to add both leaves and sawdust for the carbon and then add coffee grounds and garden waste for the nitrogen. Do I have to add the carbon ratios together and the nitrogen together individually? When I did it this way I came to a very big number (E.g 25:1 + 350:1….leads to 3960:1). Help?
Also, if I don’t use vegetables can I substitute it with other greens/browns (E.g. grass clippings)?
