The performances of five biodrainage species were monitored for its soil moisture depletion, groundwater table depression and soil fertility improvement in waterlogged lowland of Indo-Gangetic alluvial plains of West Bengal. The results of the study showed that all biodrainage plantations had differential potential in extracting surplus water from deeper soil layers and consequent recession of groundwater table. Their efficiency followed in the sequence of Eucalyptus spp. > Bambusa arundinacea > Casuarina equisettifolia > Dalbergia sissoo > Musa spp. There was considerable improvement in soil properties such as pH, EC and CEC beneath plantation strips compared to field without plantation, except in eucalyptus. The variable build-up of organic C, available N, P and K in surface soil was observed under the vegetation canopy compared to non-canopy site. However, fast growing eucalyptus tree was emerged as the most potential biodrainage species to remediate the waterlogging hazards and maintained the desired soil moisture balance.
