Abstract:
Soil of Sundarban delta is rich in elements. Due to geographical position soil of Mangrove is very rich in Na, K, SiO₃, P (Mitra et al 2013). Sea is nearby and rivers fall in Bay-of-Bengal. 9 rivers like Hooghly, Matla, Raimongal, Ichhamoti, Vidyadhari, Gosaba, Canning, Saptamukhi and Herobhanga meets Delta. Mangrove soil has Organic Carbon, Na, K, SiO₄ & P. Sea water is rich in NaCl, K, P and other trace elements. Due to merging of land and water (rivers and sea) salt tolerant plants can thrives well over there. A. alba, S. apetala, E. agallocha, and other plants grow with inundated water. Mostly muddy and acidic water near mangrove. 100 km. stretches of Hooghly river which faces high tide from Bay-of-Bengal are rich in fish fauna.
