Abstract

Physico-chcmical analysis of mangrove soils in two islands (Prentice and Lothian) in sundarban areas were carried out and compared to highlight the quality of the soils that facilitate the existence as well as survival various flora and fauna to play immense role in the stability of the environment. Study revealed that there were slight differences in the grain size, pH, organic carbon and exchangeable calcium (Ca12) and magnesium (Mg12) content in soils of these two islands. The litter of the mangrove forest might. play vital role not only on the variation of carbon to nitrogen ratio (C/N) and carbon to phosphorous ratio (C/P) but also retention ability of these essential nutritional elements in soils. Ca+2 and Mg+2 were the principal cations as observed in exchange reactions. Potassiun ion (K+) recorded comparatively higher values than the sodium ion (Na+) in these soils probably due to more amnily for K+ uptake in the existing biotic community as well as trapping capacity by edaphic components in these areas.
