Abstract:

The delta region of India and Bangladesh is popularly known as Sundarbans. Agricultural productivity of the region is very poor due to higher soil salinity and poor drainage due to presence of brackish ground water table at shallow depth. Increasing land elevation through land shaping has showed to increase in crop productivity. The original lands remained waterlogged for about five months (July to November) in a year while elevated lands were never waterlogged. Soil samples were collected from uplands and adjacent original lowlands from eight different field locations in three different seasons (winter, summer and late summer) for two years. Results depicted that there was a considerable change in fertility status due to conversion of lowlands into uplands. Soil salinity decreased after changing land elevation to a great extent. Soil organic carbon (SOC) was higher in lowland situation, but permanganate oxidisable carbon (POXC) & microbial biomass carbon (MBC) was significantly higher in upland situation than lowlands. Phosphorus availability increased after increasing land elevation. Potassium and micronutrient availability was higher in lowland situations compared to upland situation.
