Re: The clay shards and pottery in TP What & Why?
Interesting thoughts about the possible effects of the pottery adjuncts in the soil on diseases, especially the effect on the ammonia in urine. The effect of excess humanure in tropical climates usually results in nasty diseases such as cholera and diphtheria which can, and has, killed many people.
I wonder if the combined use of charcoal, pottery, and whatever other stuff help sterilize,or offset, the use of human excrement.
