摘要：A field investigation was carried out to evaluate the spatial variability of physical indicators of soil quality of an agricultural field and to construct a physical soil quality index (SQ) map. Surface soil samples were collected using m grid from an Inceptisol on Ganges Tidal Floodplain of Bangladesh. Five physical soil quality indicators, soil texture, bulk density, porosity, saturated hydraulic conductivity (), and aggregate stability (measured as mean weight diameter, MWD) were determined. The spatial structures of sand, clay, and were moderate but the structure was strong for silt, bulk density, porosity, and MWD. Each of the physical soil quality indicators was transformed into 0 and 1 using threshold criteria which are required for crop production. The transformed indicators were the combined into SQ. The kriged SQ map showed that the agricultural field studied could be divided into two parts having “good physical quality” and “poor physical soil quality.”
