8. Human excreta (feces and urine) JADAM liquid ferilizer
Most of the famous Korean local brands of produce were made through the use
of human manure liquid fertilizer. ere was a saying that nothing is as sweet as that
which is grown with human manure. In Korea in the past, human manure was so
treasured that there even existed trade that bought and sold the rights to collect
human manure. However, the introduction of lush toilets as a means to attain hy-
giene and convenience completely exterminated human manure from our farming.
Human excrement and urine are permitted materials under the Organic Farming
laws. Let us re-discover this precious resource.
e Soil Association (SA), the organization that irst introduced organic certiica-
tion system in 1967 and is currently certifying over 80% of UK organic food, has em-
phasized the value of human manure. Its 2010 report “Peak Phosphorus and the
reat to Our Food Security” announced that human manure will play a vital role in
food security for the future. It affirms that phosphate rock – the ingredient for phos-
phorus fertilizer – will reach its peak production in 2033; price will soar after that. It
stresses the importance of bringing human manure back to farming. ere was a case
in 2007-2008 where phosphate rock price soared 800%. Human manure is rich in N,
P and K; it is the last option we have in the coming age of chemical fertilizer depletion.
Vegetarians produce around 400 g (0.9 lb) a day, meat-eaters about 150 g (0.3 lb). A
productive (?) person will produce 0.2 T (441 lb) of feces a year. An adult produces
about 1-2 kg (2.2-4.4 lb) of urine a day; making it 0.5 T (1,102 lb) a year. Surpris-
ingly, one day’s urine from an adult contains 30 g (1 oz) of urea. Besides urea, the liq-
uid is also rich in various amino acids and inorganic salts. Should you really keep
throwing these away? Our ancestors saw feces and urine as “money.” We need to re-dis-
cover human manure. It is foolish to lush this fertilizer away; they become nothing
but environmental pollutants when in fact they can save the environment. Let’s build
excrement-collecting toilets again on the farm. If you throw in wood chips and rice
stalks before use, the splashing won’t be so bad! A family of four will produce 1 T (264
gal) of human manure liquid fertilizer, over 2 T (528 gal) of urine fertilizer, and 2 T
(528 gal) of food by-product liquid fertilizer. What moree do you need? Look at the
analysis tables and you will see that they are all excellent sources of nutrients.
Many argue that organic farming should be combined with organic livestock farm-
ing. e reason is that they want to promote the use of livestock manure as fertilizer. I
do not understand why you would need animals when your family can produce better
quality fertilizer!
