342-44) " In view of the fact that the energy added to the soil is not directly available to the nitrogen-fixing bacteria and that small amounts of available nitrogen are always present in the soil and the error in the laboratory determination of total nitrogen by the Kjeldahl method is greater than the possible amount of nitrogen fixed by nosymbiotic bacteria we are still unable to decide th [...] U. P. 1934 4 175; 1935 4 330; 1935 5 61) we have established that the oxidation of the carbohydrates present in molasses either through the agency of bacteria or sunlight or induction and the intermediate products to carbodioxide and water liberates energy in the soil and this energy is utilised in the fixation of atmospheric nitrogen and that is why the ammonia and the total nitrogen co [...] It is interesting to note here that previous workers determined only the total nitrogen of the soil after the addition of energy-rich"168 N. R. DHAR AND S. K. MUKERJI compounds and as the difference in total nitrogen is not very high before and after the addition of energy-rich compounds to the soil they were doubtful regardinthe fixation of nitrogen in the soil by the addition of energy-rich [...] The amount of fixation of nitrogen depends on the energy available from the oxidation of the carbohydrates of molasses and the bye-products formed from the partial oxidation of carbohydrates and that is why sufficient oxygen is necessary for obtaining beneficial results and this is achieved if the soil is dug or turned over once a week or TO days during the period of eight to twelve weeks between [...] The above results also show that molasses can fix nitrogen in the soil even in presence of ammonium salts as the total nitrogen in the soil containing molasses and annnonium sulphate is greater in the end than in the beginning.
