Surface soil samples were collected using 10  m × 10  m grid from an Inceptisol on Ganges Tidal Floodplain of Bangladesh. Five physical soil quality indicators, soil texture, bulk density, porosity, saturated hydraulic conductivity ( K S ), and aggregate stability (measured as mean weight diameter, MWD) were determined. The spatial structures of sand, clay, and K S 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 I P . The kriged SQ I P map showed that the agricultural field studied could be divided into two parts having “good physical quality” and “poor physical soil quality.” SN - 1687-7667 UR - https://doi.org/10.1155/2014/379012 DO - 10.1155/2014/379012 JF - Applied and Environmental Soil Science PB - Hindawi Publishing Corporation KW - ER -
