Hi Reddy,
Natural farming is a very good practice on a long run cultivation. natural farming aims to make the minimum interference with the natural circumstances in which the desired plant species grow. the plant that you need to have, say, grains, fruits, etc., is part of an ecosystem in which it finds a place without conflict with other elements of it, viz., the soil, the moisture regime, other life forms. over time, it establishes an equilibrium that enables it to survive and produce optimally. nature is generous, and optimal produce is usually more than necessary for the survival and reproduction of the plant - so it gives a surplus to the human component of the system.Therefore, the advantages are: sustainability; retention of quality; lower expenditure in terms of inputs including labour; and production of other life forms in the system.
