摘要:The experiment was carried out to find out the impacts of plough pan on physical and chemical properties of soil. For this purpose, soil samples were collected from two locations of Basail upazila in Tangail dristrict, one having compact plough pan layer in subsoil (site-1) and other one with no plough pan layer (site-2). A survey was also conducted on land use pattern in these areas to get the causes of plough pan formation. In site-1, rice is the dominant crop and in site-2 shallow rooted crops such as mustard, potato, onion etc. are grown. In site-1, organic C, N, K, S, Zn contents were found higher and the concentrations of C, N, K, P, S and Zn decreased from topsoil to lower layers, whereas, concentrations increased to subsoil layer except P in case of site-2.
