Abstract/Description: | Soil degradation in Gosaba Block of West Bengal representing Sundarbans ecosystem was assessed based on detailed soil characterization at 1:10,000 scale. The soils of study area were severely acidic (<4.5) to moderately acidic (4.5-5.5) in reaction and associated with slight to severe salinity (>10 dS m-1). Organic carbon content ranged from 0.67 to 1.66% in surface and 0.15 to 3.4% in sub-soils. Nutrient status of soils was deficient in available N, P and Zn and sufficient in available K, S, Mn, Cu and Fe. Soil properties (pH, ECe, CEC, clay and ESP) highly influenced the availability of plant nutrients. Based on severity, soil degradation was assessed using parametric approach and results revealed that management units MU-1 (Chan-Sicl-D5-A-S3) and MU-6 (Bhu-Sic-D5-B-S1) were under moderately degraded to highly degraded condition. Other management units were grouped into weakly to moderately degraded condition. Location specific management practices have been suggested to control the existing degradation problems. |
