First of all let me apologize for the title, I don't mean to offence anyone here.
But in fact I tell the truth. Maybe I unveil another food scandal! ;-)
Chinese farmers have a clever way to make compost. They re-use poo and pee!
Farmers will water the vegetable and the earth with the compost: a mixture of poo and pee
Of course when the vegetable grow they don't spray the compost anymore!
So in fact we don't really eat any of this :-)
It takes a minimum of 5 days to make this.
You should mix together pee and poo. You should water it every two day.
As you can imagine it doesn't smell good.
