Waterlogged wasteland treatment through agro-forestry: A review
Journal Title: Journal of Applied and Natural Science - Year 2017, Vol 9, Issue 1
Abstract
India covers 147.75 mha degraded area, whereas 6.41 mha area confined to waterlogging problem in Bihar, Maharashtra, Gujarat, Uttar Pradesh, Orissa, West Bengal, Punjab, Tamil Nadu, Andhra Pradesh, Haryana, Kerala, Rajasthan and few other states. The transpiration principle of plants is used in bio-drainage treatment to reclaim such problematic areas sustainably. Evergreen broad leaved species recorded high transpiration rate and contribute highly in reclamation of waterlogged saline soils. Short rotation fast growing tree species like Salix, Eucalypt, Acacia, Albizia, Terminalia, Prosopis, Populuswere the suitable species for such areas. Agri-silviculture, agri-horti- silviculture, silvi-pasture, multipurpose woodlots, strip plantation and boundary plantations were widely used for reclamation of saline-waterlogged conditions of India. In agri-silviculture system, Eucalypt based agroforestry systems are widely used for reclamation of waterlogged areas as compared to other woody plant based systems. 0.84–0.86 m total drawdown of ground water in 3 years Eucalypt tree species. The vertical and horizontal root spreading of tree species is one important character for capturing and transpiration of excess water from waterlogged area. From the present investigation, longest root system was recorded from Prosopis cineraria (20-60 m) species.
