Groundwater suitability for irrigated agriculture in Alluvial Bengal delta plain: Areview

<p>Groundwater is a vital source of irrigation and domestic purposes in Bangladesh, hence, it must satisfy the water quality guidelines. The study has selected eleven (11) Districts Bangladesh collect secondary data regarding groundwater. Several indices, such as soluble sodium percentage (SSP), adsorption ratio (SAR), magnesium (MAR), residual carbonate (RSC), Kelly’s (KR), permeability index (PI), (IWQ) are applied to evaluate quality. According IWQindex, results showed 25.5% samples fell highly suitability type, whereas 33.5% exhibited low remaining 41% were medium for purposes. values SAR, SSP, RSBC, MAR indices that about 31-64% very good, 5-20% poor same purpose. TDS, EC, total hardness good 88-93% fair excellent salinity hazard was found groundwater coastal areas completely unfit irrigation. findings would help improving management resources agricultural Bangladesh.</p>
