In organic farming, organic fertilizers and manures like compost, vermicompost, cow dung manure, etc. are used and added to farmlands from external sources. In natural farming, neither chemical nor organic fertilizers are added to the soil. In fact, no external fertilizers are added to soil or give to plants whatsoever. Organic farming still requires basic agro practices like ploughing, tilting, mixing of manures, weeding, etc. to be performed. In natural farming there no ploughing, no tilting of soil and no fertilizers, and no weeding is done just the way it would be in natural ecosystems. Organic farming is still expensive due to the requirement of bulk manures, and it has an ecological impact on surrounding environments; whereas, natural agriculture is an extremely low-cost farming method, completely moulding with local biodiversity.
