There is much talk of Compost Teas needing vigorous oxygenation to prevent the build up of toxic microbes. One of the key points made in this context is that E coli does not thrive in oxygenated water, and so this makes the compost tea 'safe' to use. In fact many compost teas have been used anaerobically - ie without air bubbling, for many years by different cultures, Japanese, Korean, and widely in South America. E coli is a facultative bacteria, which means it is able to grow in both aerobic and anaerobic environments. We will be posting more discussion on this shortly to explain our understanding of how we use both aerobic teas and anaerobic for different purposes on the farm. We would welcome feedback and ideas on this!
What are anaerobic compost teas?
We reproduce different microorganisms in Anaerated processes. We isolate, reproduce and then activate them ready to spray. We work with specific microorganisms such as Bacillus Subtilis or lactic acid bacteria among others or just native microorganisms and this high range of beneficial microbiology. We place the microbe culture in solution for a minimum of 30 days before using them as a foliar spray.
What is anaerobic tea for?
We work with a wide range of microbes depending on which brew we are dealing with. They can be used for specific situations or general pest and disease control on the farm or garden. These brews can be used for healthy practices in general, with the purpose of feeding the plant, and to re-cover and re-activate soil biology, creating a proper balance in harmony with local conditions.
How do they work?
At the end of the process the product content will contain a high range of available minerals (macro and micronutrients, trace elements ...), Organic Acids, proteins, vitamins, enzymes, carbohydrates, amino acids and different microbiology that will work in symbiosis with the natural processes in the plant and soil, developing and improving a nutritional and biological balance and a natural defence mechanism.
