Compost tea is a common input on CNG farms, but a few considerations should be made when brewing and applying. If the tea is made with finished compost and/or vermicompost and contains no additives, it can be applied without restriction. The addition of fish emulsion (or other additives like molasses, kelp, etc.) increases the risk of e. coli, listeria, and other harmful bacteria. Therefore, for applications of compost tea made with unfinished compost or raw manure and/or with additives mixed in, CNG requires the same restrictions as raw manure (i.e. applied according to the 90/120 rule). If additives are mixed into finished compost tea and applied within an hour of mixing, the tea can be applied without restriction.
