Soil and land use surveys in Puthia Upazila (small administrative unit) of the district of Rajshahi, Bangladesh under the AEZ (Agroelcological Zone)-11 were carried out to examine the changes in physical properties and land use patterns in between 1989 to 2009. Significant changes in land types, land use patterns along with crop diversification were identified. High land (HL) decreased 15.7 % in 2009 compared to 1989 survey. Medium high land (MHL) increased 124% and medium low land(MLL) decreased significantly (55%) during the survey. Sara, Tahirpur, Gopalpur, Ishwardi, Sukdebpur, Mehendigonj and Ghior soil series were identified at the time of survey. Cropping patterns were also changed in 2009 compared to 1989. In single cropped area mixed crop and relay crops were used for achieving food requirements. A large area was converted to permanent mango orchard which may be alarming for the agricultural planners, scientists and other concerns. About 278 ha agricultural land converted into non-agricultural land for making permanent buildings and other constructions. About 46.2% top soils were identified as loam soil, 38.5% as clay loam soil, 1% as clay soil, and 14.3% as miscellaneous soils in Puthia Upazila. Double and triple cropped areas were significantly increased in 2009 compared to 1989. For sufficiency of food, new crop varieties and high yielding varieties of different crops were introduced under crop diversification programs within the study period. For conservation of soil health, black gram, mung bean and other leguminous crops were introduced in some areas. Soil test based fertilizer application program would be useful to maintain soil fertility and provide continued awareness of ongoing changes in cropping patterns.
