Let us not put both these words together .
Natural Farming e.g. ZBNF etc. Uses Cow Urine , limited Dung etc. and almost no Menure
Organic Farming i.e. Generally followed Vermicompost , Compost.
Seen most of the Titles as Natural Organic , which is misleading.
Both are totally different technologies .All those who wants to migrate from Chemical Farming should know the difference between these two and Choose appropriate option as per their conviction.
