Excerpt from Memoirs of the Department of Agriculture in India: Azotobacter and Nitrogen Fixation in Indian Soils The enormous area of cultivated soil in India which is never likely to receive any addition of nitrogenous manures but is yet the only source of nourishment and livelihood of millions of cultivators, makes the nitrogen problem in this country of paramount importance from the point of View of the transference of this element from the air to the soil by various natural agencies. The importance of leguminous crops in this respect cannot be overestimated, but in actual practice the fact remains that enormous quan tities of nitrogen are annually going out of the country in the form of agri cultural exports, whereas the amount actually added to the soil by the cultivation of Leguminosce cannot be considered sufficient to replace this loss, nor is there any importation of artificial nitrogenous manures in quan tities worthy of consideration. Another source of soil nitrogen remains, namely, the non-symbiotic organisms such as C'lostridium and Azotobacler which, so far as our knowledge at present carries us, are largely responsible for the present state of fertility of soils all over the world.
