Abstract

The fine root biomass and soil microbial biomass were estimated from two soil depths (0-15 and 15-30 cm) in the tropical moist forest (Charkoshe Jungle) located in Sunsari district, eastern Nepal. Soil samples were analyzed also for their physico-chemical characteristics. In the upper soil depth (0-15 cm) soil organic carbon and total nitrogen were 3.07 and 0.24, respectively. Soil microbial biomass carbon and biomass nitrogen were 676.6 μg g-¹ and 59.0 μg g-¹, respectively, while fine root biomass was 2.74 t ha-¹. Soil organic matter decreased by 56% in lower (15-30 cm) depth in comparison to upper depth. Similarly, the fine root biomass also decreased in lower depth by 44% in comparison to upper layer. Soil organic carbon, total nitrogen, soil microbial biomass carbon and biomass nitrogen showed negative correlation with fine root biomass.
