When we talk about organic farming, we were still describing a technique of agriculture that consists of various interventions with fertilizers, tilling, weeding, and even using pest biocontrol measurements. On the other hand, natural farming is a "view" or a way of agriculture made by "Masanobu Fukuoka" which is basically a "do-nothing" strategy where there is no intervention with any kind of the traditional and modern agriculture practices, the farmer uses the complexity of interactions between the diverse plants and animals to deter the need of pesticides and chemical inputs. So basically no insect, plant, or soil is harmed in the process at all, it's as if you are putting together different pieces of a puzzle to form a natural cycle between every single living organism on your farm.
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.
In natural farming, decomposition of organic matter by microbes and earthworms is encouraged right on the soil surface itself, which gradually adds nutrition in the soil, over the period.
Organic farming still requires basic agro practices like plowing, tilting, mixing of manures, weeding, etc. to be performed.
In natural farming there no plowing, 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 molding with local biodiversity.
I understand that organic agriculture uses fertilizers such as compost, vermiculture and animal guano (without antibiotics or hormones in its management), incorporation of waste and if it needs extra nutrient contributions, those from pure rocks are used, without processes or additives of chemical origin or synthetic chemical. In addition, organic agriculture should be self-sufficient in the natural fertilizers initially mentioned, since it ensures that the components have had the required handling, origin and quality, unless the external supplier certifies their origin and processes. In the case of natural production, although they may not use hormones or antibiotics or any prohibited product required for organic production, they do use herbicides, which is why it is called NATURAL, but cannot be classified as ORGANIC.
Organic farming is regulated by standards and principles. Organic farming requires returning to the land what is taken. On the other hand, natural agriculture remains a picking agriculture. It is not governed by any standard. Organic farming ensures animal welfare and the link to the soil (a fundamental principle for reducing greenhouse gas emissions).

This paper is describing practical applications of natural farming and its benefits: money savings, yields, increased profits, etc. There are many benefits and some drawbacks.
Organic farming is exclude use of synthetic chemical fertilizers, PGR, livestock feed additives and pesticides in order to sustain the ecological balances by applying organic ammendment only like organic manures, bio-fertilizers, and bio-pesticides etc..These organic manures have to be arranged from outside that is external sources rather than manipulating the natural environment by managing in- farm resources or crop wastes or animal wastes so called natural farming... Use of Jeevamrit and Beejamrit prepared by cow dung, cow urine and other natural inputs is natural farming...
