Zero Budget Natural Farming (ZBNF) is a scalable model of low-input/high output agriculture that eliminates the use of synthetic external inputs by utilizing local farm-based inputs and regenerates soil health. ZBNF is being implemented by the state government of Andhra Pradesh, which is transitioning 6 million farmers and 8 million hectares to 100% chemical free agricultural practices by 2024, making Andhra Pradesh the first natural farming province in India.
