The serious issues faced in agricultural lands and ponds are due to salinity. As salinity cannot be detected on high scales through satellite images, in this study the remotely sensed turbidity has been compared and studied with laboratory-measured salinity. The high-resolution Sentinel-2 MSI data with optimum bands for water quality detection have been used in this study. The small agricultural ponds in the study area were not detected by the conventionally used water indices, as the ponds were surrounded by homestead vegetation. Hence, a new index called Pond Probability Spectral Index (PPSI) was formulated and used in the decision tree algorithm to delineate all the ponds. Turbidity indices were used over the extracted ponds to classify them into three classes, clear, turbid and highly turbid. From the field accuracy assessment, one of the turbidity indices out performed in segregating the ponds with an overall accuracy of 83.3%. It was also found that salinity was inversely proportional to turbidity only when the turbidity value was greater than 100 NTU. The total estimated pond area (average of 3 seasons) in the Sundarban region was 471.66 km 2 .","PeriodicalId":285583,"journal":{"name":"Journal of the Indian Society of Coastal Agricultural Research","volume":"252 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115848943","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The physicochemical analysis of the soil showed that the soil was alkaline in nature with high salinity. The organic carbon, total nitrogen and available phosphorus status of the soil were low while the available potassium content was high. Bacterium N8 isolated from the rhizospheric soil possessed multiple growth-promoting activities i.e., the highest phosphate solubilizing efficiency (8.52 mg P g -1 of sugar), nitrogen-fixing capacity (0.7 mg of N g -1 of sugar), phosphatase enzyme activity and tolerance to salinity at 6% NaCl. A morphological study of this bacterium indicated that it was gram-positive, rod-shaped and was present in both single and chain form. The PCR amplification of genomic DNA (using 16S rDNA specific primers) showed a clear visible band at 1.5Kb. Sequencing of the amplicon followed by BLAST analysis depicted that the bacterium N8 exhibited the highest similarity (99%) with the genus Bacillus . The NCBI-Gen Bank accession number of the bacterium was SUB416213 N8 MH489431. The presence of members of the genus Bacillus in the rhizosphere soil of Suaeda nudiflora from Sundarbans is being reported for the first time. This study has led to a significant avenue for the use of the N8 bacterium as a potential salt-tolerant phosphate solubilizing bio-inoculum for improving nutrient availability in the coastal region.","PeriodicalId":285583,"journal":{"name":"Journal of the Indian Society of Coastal Agricultural Research","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128534548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
