Nitrogen status of soils of subtropical region of Jammu and Kashmir (JandK) state was evaluated by studying both surface and profile samples from different locations. In surface soil samples, the total N ranged from 460 to 1830 ppm, available N 75.43 to 599 kgha-', NH/- N 5.40 to 30.10 ppm and (N02- and N03-) - N 2.80 to 16 ppm. In general, the depth wise distribution of different forms ofN showed a decreasing trend with increasing depth. C:N ratio ranged from 4.19 to 13.77 and mostly narrowed with increasing depth. pH did not show any significant relationship with any form of N. Organic carbon gave a significant positive correlation with all forms of N in both surface and profile samples. Clay content did not show a significant relationship with different N forms but showed a positive relationship with total N in surface soil samples.
