Was traveling in Thai country side this weekend and we have a lot of laterite here (red, iron rich soil) where locals tend to correct for it with bio mass like coconut husks as temporary solution which made me wonder what is a more permanent solution? And that's just biochar - literally almost inverse of everything laterite is!
