Abstract

Soil samples were collected from the three locations of Umvita, Ghona Madar Danga, and Taligati. Among the three locations, Umvita and Ghona Madar Danga were divided into two polders i.e., Polder -25 (Beel Dakatia ) and Polder-27. However, Taligati was in Polder - 25 (Beel Dakatia) only. Soils were analyzed for moisture content and soil nutrients (Ca, Cu, Fe, Zn). The moisture content in the soil of Polder -27 was relatively lower than that of the moisture content in the soils of Polder -25 (Beel Dakatia ), which indicated t he presence of high concentration of organic carbon and humic acid. The average concentration of essential macronutrient Ca and micronutient Fe and Zn were found to be lower in the soil of Polder -25 (Beel Dakatia) compared with the soil in Polder -27. However, the concentration of Cu was higher in Polder -27 in comparison with Polder-25 (Beel Dakatia). The lower value of soil nutrients in Beel Dakatia indicated loss of soil fertility.
