Observations on the Edapho-Microbial Nature of Indian Botanic Garden, Howrah
Abstract
The edapmo-microbial nature of Indian Botanic Garden was assessed. The activities of Azotobacter were used as an indicator to determine the suitability of edaphic conditions for plant introduction. It was observed that the Hooghly River (Ganga) front had comparatively higher clay content and organic carbon. The water holding capacity, cation exchange ability, pH, porosity and available nutrients such as nitrogen and phosphorus and azotobacter activities of the river site were comparatively superior to the other sites. The middle stretch of the garden area was observed to be more saline than other two stretches. The area towards humaq, settlements was exposed to severe anthropogenic interference. Consequently, the microbial population was diminutive here with relatively inferior edaphic characteristics.Downloads
