Waterlogged and subsequent soil salinizations are the two major causes of degradation of irrigated agricultural lands making it unfit for crop cultivation. Surface drainage is inefficient to combat the problem adequately. Subsurface drainage technology is an effective control measure for both. However, this technology is to some expensive and has an associated problem of safe disposal of the drainage effluents. Bio-drainage is considered by some as an effective alternative, in which water and salt tolerant plant species are grown to remove the salt solutions from saline and waterlogged lands in an eco-friendly and economical manner. Bio-drainage has now been portrayed as a land reclamation option, confirmation of salt uptake from saline lands having established plantation needs to be carried out.
