“…This results fully acquiesced with Islam et al, (2016). Mondol et al, (2013) reported that the average pH value was 6.7 and 6.5 during wet and dry season at the vicinity of the Tejgaon industrial area adjacent to Dhaka City Corporation. Njoku (2013) recorded the pH variation (5.57-6.52) in the Niger Delta Region of Nigeria.…”

“…The lowest concentration of EC was recorded 43µs/cm at non-polluted site during monsoon (Table I). Mondol et al (2013) recorded the amount of EC 25-551 µs/cm at the vicinity of the Tejgaon industrial area adjacent to Dhaka City Corporation. Soil EC is a measure of the quantity of salts in soil (salinity of soil).…”

“…This low amount of organic matter content also indicate low total nitrogen content in the soil. Mondol et al (2013) recorded the amount of organic matter 4.87-11.55% at the vicinity of the Tejgaon industrial area adjacent to Dhaka City Corporation. Organic matter was found to increase cation exchange capacity that aided in the decomposition of dead algae, consume oxygen and release toxic gas like CO 2 , H 2 S and NH 3 (Colt and Armstrong, 1981;Boyd, 1995;Camargo et al, 2005).…”

“…Soil pH was determined by Hanna soil pH meter (Islam et al, 2016). EC was determined by Hanna EC meter (Mondol et al, 2013), Soil Organic Matter (SOM) was measured by Walkey and Black wet oxidation. Soil texture (% of sand, silt and clay) in the study area was analyzed by the hydrometer method described by Huq and Alam (2005), modified from Bouyoucos (1936).…”

The present study was conducted to find the status of different soil quality variables of the Meghna River during the period from September, 2015 to March, 2016. The values of different soil quality parameters such as silt, sand, clay, bulk density, pH, EC and organic matter fluctuated between 13.33-58.33%, 29.25-88.42%, 4.92-17.42%, 1.43-1.71g/cm3, 6.86-8.06, 43-942.67µs/cm and 0.24-3.1% respectively. The heavy metals were analyzed by Atomic Absorption Spectrophotometer (AAS). The observed order of heavy metals mean concentration in sediments Fe> Pb >Cr > Co > Cd in mg/kg, respectively. Significant differences (p<0.05) was found in the values of soil organic matter of the Meghna river in terms of sites. But the value of silt, sand, clay, bulk density, pH and EC exhibited no significant variation with sites. The concentration of silt, sand, clay, bulk density, pH, EC and organic matter showed no significant variation with seasons (p>0.05). Very strong positive correlation between Cr vs EC (0.965), Cd vs EC (0.962), Cd vs Cr (0.959) and bulk density vs % sand (0.951) was observed at the significance level 0.01. Fe vs % sand (0.944), Cd vs Fe (0.824), Pb vs % O.M (0.823) and bulk density vs Fe (0.822) showed very strong positive correlations at 0.05 level of significance. The concentration of the soil parameters indicate that the river is being polluted and the statistical analysis proved that anthropogenic sources are the main contributor.Bangladesh J. Sci. Ind.

The present study was carried out to monitor and assess the surface soil quality parameters of the Sitalakshya River, Bangladesh. The soil samples were collected from Kanchpur Bridge and Atlapur during rainy and winter season. Soil texture is an important tool that aids in organic matter retention, minerals dispersal, microbial biomass, and other soil properties. The soil of the study area was recorded sandy loam and loam. The concentrations of soil parameters ranged for EC: 65.7 μS/cm-99.83 μS/cm; pH: 6.67-6.97; organic matter: 0.43%-0.66%; and organic carbon: 0.23%-0.35% in the soil of the Sitalakshya River. Most of the parameters showed no substantial variations in respect of sites and seasons (p>0.05) except electrical conductivity and pH (p<0.05). Statistical analysis like correlation matrix exposed the close relationship between organic matter and organic carbon. The soil of the Sitalakshya River has low nutrient contents that are not enough for the plants and organisms. Rapid industrialization and the huge establishment of brickfields are the major factors behind this less productive ecosystem. The river must be protected from further deterioration by taking fruitful management plan. This preliminary study will be a useful tool in the conservation plan. This will also help the future researchers who want to work on the river. Contribution/Originality: The paper contributes the first logical analysis of the soil quality parameters of the Sitalakshya River. The study demonstrated the preliminary ecosystem condition of the river. This will provide baseline information for researchers and policymaker in the conservation issue. 1. INTRODUCTION The soil is a natural component of the environment that constitutes of mineral matter, water, air, organic matter and living community that varies according to place and time [1, 2]. Climate affects the type of rock weathering, removal and the redeposition of materials by wind, water, and glaciers that regarded as a crucial factor for soil formation [3]. It forms a natural buffer and filter system in water and offers a wide range of ecosystem services (e.g. food, fiber, water, and timber) [4, 5]. Soil exert great influence on the environmental quality and have an impact on the climatic conditions; water quality; nutrient cycling; and cultural services (e.g. aesthetic, spiritual, and recreational purposes) [6-8].
