Comparative study on physico chemical parameters of soil and water among three aquatic successional stages at Jahangirnagar University campus

Abstract

This study was conducted on the physico stages (submerged floating, and emerged) of the wetlands of Jahangirnagar were selected along the study area and studied during January 2010 to October 2010. On an average, water P H , dissolved oxygen, acidity, alkalinity, total hardness, nitrate and free CO contained 6.2 ± 0.19; 6.85 ± 0.21mg/l; 36 and 1.6 ± 0.52 mg/l respectively & soil ± 0.18; 6.17 ± 0.89%, 0.27 ± 0.02mg/gm values of water P H , dissolved oxygen, acidity, alkalinity, total hardness, nitrate and free CO stage water were 6.86 ± 0.88; 6.82 ± 0.42 11.2 mg/l and 1.5 ± 0.52 mg/l respectively. And soil matter, were 6.38 ± 0.08; 6.13 ± 0.94%; For emerged stages water P H , dissolved oxygen, floating stage were 6.8 ± 0.26; 6.83 ± 0.37 8.69 mg/l ; 1.7 ± 0.48 mg/l respectively. And were 6.43 ± 0.11; 6.11 ± 0.95%; 0.40 ± 0.02 mg/gm; 0.96 and negative correlations among these parameters were also studied. Strong positive correlations were found in between organic carbon-organic matter (r=0.99) in submerged stage, P 0.79), acidity-free CO 2 (r=0.73), organic carbon stage, P H -dissolved oxygen (r=0.81), organic carbon correlation. Strong negative correlations were found in between alkalinity emerged stage. Organic carbon and organic matter showed significantly strong correlation (r=0.99) in all studied stages. From this study, it was found that, the water P stages than submerged stage. Dissolved oxygen was higher in submerged stages than floating and emerged stages. These may be because of submerged stage was early stage of decomposition process, variation of acidity, alkalinity and total hardness were found in three succession stages. High concentrations of water nitrate were obtained; this may due to the decomposition process on the lakes.

“…Similar results were also recorded by Sultana and Huda (2013) in the wetlands of Jahangirnagar University campus. The present result is also supported by the result (pH 6.99 to 7.0075) obtained by Medudhula et al (2012) from lower manair reservoir of Karimnagar district, Andhra Pradesh.…”

“…Similar findings were observed by Sultana and Huda (2013) in the wetlands of Jahangirnagar University campus and Kumar and Oomen (2011) in water bodies of Gujarat, India. Calcium and magnesium are essential to fish for metabolic reactions such as bone and scale formation.…”
