Soil Profile and Physical Properties of Soil of Research Field in Rajshahi, Bangladesh

Soil profile and physical properties of soil are important for crop cultivation and horticultural practices. This study was carried out to identify the soil profile of the research field of Institute of Environmental Science (IES) of University of Rajshahi during December 2024-February 2025. For getting the Soil Profile of Rajshahi University campus, two bores were dug in research field. The soil samples were collected from two sites at a considerable depth with possible variation of the horizons. A total 12 sediment samples from two soil profile sites were collected and analyzed in the laboratory of Department of Geology and Mining of University of Rajshahi. In 1st soil profile site (SP1), soil horizon A was found at 0 - 15 cm, E & B1: 15 - 60 cm, B2: 60 - 78 CM, C1: 78 - 100 cm and C2: 100 - 200 cm, whereas in the 2nd soil profile site (SP2), the soil horizon was found at different depths, A: 0 - 30 cm, E & B1: 30 - 58 cm, B2: 58 - 83 cm, C1: 83 - 163 cm and C2: 163 - 203 cm. From physical soil properties analysis, the particle size was found dominantly sands with almost identical silt and clay. Major soil textures of the studied profiles are sandy loam, sandy clay loam, loamy sand and medium loam, and most cases, soil order is mainly Entisols. The soil composition of IES research field of University of Rajshahi was found to suitable for diverse agricultural activities, however, challenges like water retention and soil fertility are problematic in some areas of this research field.
