Zero Budget spiritual Farming means for all the crops, the production cost will be zero. In the Zero Budget Natural Farming nothing has to be purchased from the outside. All things required for the growth of the plant are available around the root zone of the plants. There is no need to add anything from outside. Our soil is prosperous-full of nutrients. How much nutrients the crops takes from the soil? Only 1.5 to 2.0 % Remaining 98 to 98.5% nutrients are taken from air, water & solar energy. Agriculture Universities says false that we have to add fertilizers from outside. If science says, that 98% crop body is constituted by air and water, then where is the need to add the fertilizers from the outside? Every green leaf produces the food throughout the day. These green leafs are food producing factories. What is used the leaves for producing the food? It takes carbon dioxide & nitrogen from the air, water from the canal, river or well given by the monsoon clouds, and solar energy from the sun for producing the food. Every green leaf of any plant produces 4.5 gram carbohydrates per square feet surface, from which we get 1.5 gram grains or 2.25 gram fruits. For preparing this food, the plants take necessary elements like air, water and solar energy from the nature, not from us. Monsoon clouds do not send any bill for the water that he supplied. Neither air sends bill for the nitrogen it supplied or the sun for the solar energy. All these are available free of cost. Green leaves do not use the technology of the Agriculture University for taking CO2 from the air or solar energy from the sun. Whether monsoon clouds use the technology of Agriculture University for giving rainwater? No! All these elements constituting 98% body of the plant are available free of cost. Remaining 1.5% nutrients taken from the soil are also available free of cost as it is taken from the prosperous soil which is enriched with these nutrients. Moreover, for this it does not use the technology of the Agriculture University.
