Abstract: The application of FYM maintained or increased nitrogen status of LTFE soils. In treatments of FYM (T8, T9), the status of nitrogen fractions increased. In case of all the fractions of nitrogen found significantly maximum in T9. At initial stage of experiment (1st year) available nitrogen status of LTFE soils falls under lower range (<250 Kg N ha-1), also after 5th, 10th, 15th and 20th year it decreased to lower range (<250 Kg N ha-1) in most of the treatments, except treatments which received FYM (T8 & T9) which showed medium range in available-N status of LTFE soils. Further It was established here that for maintaining N fertility of soil at long run, addition of FYM is essential with inorganic fertilizers. Similar results were also recorded in case of all other fractions of nitrogen. In LTFE soils the percent depletion of different forms of nitrogen was interesting under all treatments. The total-N and O. C. showed positive depletion after a span of 20 year except T1, T5, T6 and T9 and available-N exhibited positive depletion except treatment T1, T5 and T6.
