[Stoves] ***SPAM*** Dung Rocket Stove - Failed Test

[Anand Karve]

I have repeatedly shown that plants kill, digest and absorb bacteria. Dung
is a good source of bacteria. An ancient Indian way of providing plants
with nutrition is to mix dung, sugar and some soil and ferment the mixture
in a big barrel. After three days, this bacterial soup is given to plants
along with irrigation water. A survey made by a student of mine showed that
thousands of farmers follow this practice. They get high yield without
using any other source of plant nutrition.
Yours
