Hello, Mr. Cho,
This year most farmers in our area have slaughtered all their cows to prevent an epidemic of Foot-and-mouth disease (구제역), which made obtaining good quality manure difficult.
While searching for other sources of base fertilizer, I remembered your lecture on human manure.
I thought, since my family has been following JADAM SESE lifestyle (eating diverse whole organic grains and leafy greens, exercising, avoiding synthetic hygiene products and antibiotics) for a long time, it might be a good time to start building a JADAM no-smell composting toilet.
You often say that a high quality compost should contain 1/3 manure and 2/3 sawdust. So I did the numbers.
If my family produced 500 kg of human manure a year, then every year I would have to buy 1000 kg (or 5 cubic meters) of sawdust to make compost using your method.
I live in a desert, there are no woodworking operations here, and 1000 kg of sawdust would cost almost as much as my family spends annually on food.
So I have questions.
1. Can I use less sawdust?
2. Can pine tree sawdust be used?
3. Can sawdust be substituted with other materials like shredded barley straw or old shredded hay?
4. Your ancestors used human manure to grow crops for thousands of years. Did they mix it with sawdust too? If not, why can't we use the ancient method today?
Thank you!
