To provide low amounts of nitrogen with an organic fertilizer, choose an organic material that contains lots of carbon and little nitrogen. ... This reduced flavor ...

Plant and Soil Sciences eLibrary - passel.unl.edu

The microorganisms take nitrogen from the soil for proteins. Consequently, for a time the concentration of inorganic nitrogen in the soil declines, and may be deficient for plant growth. As residue decomposes, the C:N ratio narrows. At a ratio of approximately 17:1, nitrogen becomes available for plant use.
