ABSTRACT

Hippophae salicifolia D. Don or Sea buckthorn is one species that has great potential for improving ecological and economic developments in the mountain areas of North Sikkim. The plant is found naturally at altitudes ranging from 2,377 to 3,093 m. in riverine (riverside or torrential side) and non-riverine (non river or non torrential side) areas where geo-physico-chemical parameters like aerial temperature, aerial moisture, soil pH, soil temperature, and soil moisture varied significantly. We analyzed ecological parameters and species association using standard quadrates. Actinorhizal plants invade nitrogen-poor soils because of their ability to form root nodule symbioses with N2-fixing actinomycetes known as Frankia. Variation in nodulation with respect to plant height was also observed. This was higher in riverine areas compared to non riverine sites at higher altitudes.

Characterization and Classification of Soils of Upper Rangit Basin in Sikkim

 

Sunita Das and M.K. Bandyopadhyay

 

ABSTRACT

Twenty soil series have been identified in nine broad landform units through reconnaissance soil survey on 1:50,000 scale. Soils are usually brown (10YR 2/2) to dark brown (10YR 3/3) at surface due to high organic carbon content. Soil structures are fine, weak, granular in surface and fine medium, moderate and subangular blocky in sub soils.  Soils are acidic (pH 4.3-5.3), pH values are comparatively higher in subsoils. Base saturation percentage of soils is fairly high.  Three soil orders viz. Inceptisols, Entisols and Mollisols have been identified. Entisols characterized with no diagnostic subsurface horizon cover an area of 11118.70 ha. Inceptisols with cambic subsurface horizon covers 59164.95 ha. Mollisols with mollic epipedon are distrubuted in 52855.56 ha.
