Abstract

Peat soil of Bangladesh is seasonally flooded, poorly to very poorly drained, very dark greyish brown to black organic soil. These soils include alternate layer of peat and muck, sometimes peat and mineral layer at the top of the profile. Two popular management techniques are practised in these areas namely, ‘Sharjan’ and ‘Gher’ procedure. In peat soils organic matter content is very high. Due to the presence of highly decomposed and partially decomposed orgnic matter, there is a possibility of root injury by H₂S gas. The main landuse patterns are: fallow-broadcast aman, fallow-mixed aus and broadcast aman, Boro-shrimp and Boro-mixed shrimp and T. aman. There are some possibilities to improve these soils having mineral layer at the top of the profile and by allowing the sediments settling on full organic soils.
