The UK newspaper the Guardina, had a good article on this subject a few days ago. See
A short quote from it:

Should we panic?

No. The spread of the virus outside China is worrying but not an unexpected development. It increases the likelihood that the WHO will declare the outbreak to be a public health emergency of international concern. The key issues are how transmissible this new coronavirus is between people and what proportion become severely ill and end up in hospital. Often viruses that spread easily tend to have a milder impact.

Healthcare workers could be at risk if they unexpectedly came across someone with respiratory symptoms who had travelled to an affected region. Generally, the coronavirus appears to be hitting older people hardest, with few cases in children.

I recycle used potting soil/mix by using it as bedding for my worm bins (vermicomposting).

I use AsciiDoc to convert simple plain text source into multiple output formats: "AsciiDoc is a text document format for writing notes, documentation, articles, books, ebooks, slideshows, web pages, man pages and blogs. AsciiDoc files can be translated to many formats including HTML, PDF, EPUB, man page."

DocBook and LaTex are among the supported output formats. This way you don't need to know LaTex of DocBook at all.

According to Master Cho's original instructions you can use an alternative method by mixing leaf mold with the rice directly. See under the heading "Collecting from leaf mould"

I have the Kindle version of the JADAM book, that I read on my Lenovo tablet. The son does not provide this information in his JADAM book. He found the methods of his father too complicated, so he simplified things. Some things like creating LAB (Lactic Acid Bacteria) he just left out.

There are fungi that trap nematodes. From

Nematode trapping fungi, or “nematophageous fungi,” are carnivorous fungi that have developed methods and structures that enable them to successfully trap and consume nematodes. Nematode trapping fungi are responsible for keeping the nematode population in check and are an important part of the subsoil ecosystem. These fungi prey on nematodes and are in turn consumed by organisms on the next trophic level. Nematophageous fungi use several methods to hunt their prey. These methods include living within the nematode and slowly consuming them as well as spreading diseases through nematode populations. The fungi also live in the soil and set traps for the nematodes to squirm into.

It also has a picture, which is also used in the "Teaming with Microbes" book by Jeff Lowenfels and Wayne Lewis. More pictures can be found by Googling for "nematode trapping fungi".

From :

David Whitlock has not showered or bathed for 15 years, yet he does not have body odour. “It was kind of strange for the first few months, but after that I stopped missing it,” he says. “If I get a specific part of my body dirty, then I’ll wash that specific part” – but never with soap. As well as germs, soap gets rid of the skin’s protective oils and alters its pH level. Although Whitlock appreciated gaining an extra 15 minutes a day from soap-dodging, his primary motivation was to encourage friendly microbes to live on him in symbiotic harmony. The bacteria get to feast on the ammonia from his sweat and he gets low-maintenance, balanced skin.

I wonder whether using lactic acid bacteria (LAB) would help to rebalance the microbiome on our skin and armpits.

A previous thread on this topic with an interesting link how a young boy set up such a system:
Some other links: can be found at and

You could set up 2 systems, one for the poo and another one for the litter.  

You could test the pH level by preparing a sample following the procedure mentioned on page 4 of
No need for an expensive pH meter, a pH test strip, although not very accurate, will give you an idea whether adding calcium carbonate is necessary.

Make sure the bin or whatever you will be using has good ventilation. Ammonia gases will kill worms

An alternative would be to create the KNF (Korean Natural Farming) FAA (Fish Amino Acid). See KNF Fish Amino Acid for the original instructions found in Cho Han Kyu’s Natural Farming Handbook.

PS I don't understand why Natural Farming  automagically links to Eric Fisher's book that I haven't bought yet . I don't have that book. I refer to that term as defined in

I brew compost tea with a Mini-Microbulator that I built using a plan that I bought from Tim J. Wilson's. A video demonstrating it:  

A video of the 50 gallon version:

But I also use the much more simpler procedure to create Jadam Microorganism Solution (JMS), that has to be diluted 10x before using. For JMS  you don't need a pump and very little ingredients. See
