The value of root mass was higher (4.28 t ha<sup>-1</sup>) in the undisturbed stand than the disturbed stand (2.04 t ha<sup>-1</sup>). The biomass of smaller fine roots (&lt;2 mm diameter) was 1.51 and 3.2 t ha<sup>-1</sup> in the disturbed and undisturbed stands respectively. Most of the fine roots were present in the surface soil layer (0-15 cm), in both the disturbed and undisturbed stands (67% in the disturbed and 64% in the undisturbed). The nitrogen stock in the fine roots was more (38.61 kg ha<sup>-1</sup>) in undisturbed stand than the disturbed stand (16.93 kg ha<sup>-1</sup>). More nitrogen was confined in the fine roots of &lt;2 mm diameter in both undisturbed (28.8 kg ha<sup>-1</sup>) and disturbed (13.59 kg ha<sup>-1</sup>) stands.</p> <p>DOI: <a href="http://dx.doi.org/10.3126/njbs.v2i0.7484">http://dx.doi.org/10.3126/njbs.v2i0.7484</a></p> <p><em>Nepalese Journal of Biosciences </em>2 : 10-16 (2012)</p> ER -
