re “night soil” — I am too tired to search for a link/”proof”, but I have heard the same thing. Not necessarily that ALL fruits and veggies are grown in night soil, but “some” is more than I care to eat. ;-)
I have to say I had not heard of this “night shade” fertilizer before other than as a type of plant. I looked briefly and this item caught my eye since a lot of product from Thailand is sold in Walmart.
Check labels....I don’t buy any food from other countries. I was really surprised to see popular brands of tuna coming from Thailand. Check Walmarts frozen fish....Thailand or some other far off place. I’m limited here to one market HEB and Walmart...yuck on both of them. HEB has more items everyday that have more spanish than english on the label.
Anyway here is the night shade item I found at “first” glance in Google.
****************
In Thailand, the septic tank system is used for night soil collection. Some night soil is disposed of directly into sewers or transported and dumped into the rice paddy fields or public areas.
