some people seem VERY confused as to the death smell in organic teas. Let me try to explain. Copied from another post of mine:
I`ve seen the sweetest smelling plants come from organic fertz which smelled like death. My soil smells like a thick Earthly smell, NOT putrefaction. Earth worms go crazy over my soil even if the fertilizer smells like death. The plants produce their own ketones. Anaerobic bacteria means it does not need oxygen for growth.
Facultative anaerobic organism - will convert to bacteria which uses oxygen.
Obligate anaerobes - will die with the presents of oxygen. All good compost will drain well and create oxygen pockets in the root medium.
Most people don`t know what the hell they are talking about. The truth is that you want heavily oxygenated tea and soil. The smell does not matter, in fact, the only kind of organic fertilizer which hurts the plants is stagnate teas which were "brewed" with low oxygen and stagnate in low oxygen environments, this promotes Obligate anaerobes. Edit: have you ever smelled a manure compost with added nutrients like blood-meal? The ammonia release is normal and one of the steps to promote healthy fertilizers. Facultative anaerobic organisms will destroy Obligate anaerobes with oxygen. Make sure your soil is well-oxygenated.
Example, don`t brew organic tea and then let it sit in a non-oxygenated container. This will promote Obligate anaerobe bacteria, this CAN harm the roots because the "bad bacteria" does not have the time to oxidize/die, creating food for "good bacteria". Smell has nothing to do with it and it is a completely natural process. "Bad bacteria" will break down the cellular walls of organic compounds quickly and with induction of oxygen, the "Bad Bacteria" will die off and be replaced by "Good Bacteria" releasing the valued N-P-K. "Bad bacteria" is like a battering ram which knocks down the cell walls of organic material.
Putrescine and cadaverine are amines which cause the dead-shit smell.
putrescine + O2 + H2O = 4-aminobutanal + NH3 + H2O2
both are completely natural by-products of lowly oxygenated environments. With the adaptation of leonardite and oxygen, both give a reduced Obligate anaerobe environment. This promotes "good bacteria" by metabolizing "bad bacteria" into food, releasing ammonia, ketones, and hydrogen peroxide (dead smell). enzymes known as catalase peroxidase will harmlessly decompose H2O2 into oxygen and water.
Ammonia convert via Ammonification: The transformation of organic nitrogenous compounds (amino acids, amides, ammonium compounds, nitrates etc.) into ammonia is called ammonification. This process occurs as a result of hydrolytic and oxidative enzymatic reaction under aerobic conditions by heterotrophic microbes.
