What kind of soil do you use?

Well, on the lighter side, I don't think I'd care for the manure smell.

I wonder how this happened.

Manure has a lot of nutrients, but most of them afraid of dirty smell. Growing plants is easier in manure than soil.
Regarding Red Soil people already using it in farms, but nowadays the soil became worst to the farmers.
