Afforestation and soil reclamation
Karanja is promoted as being able to produce oil on poor, degraded or saline soils (Murphy et al., 2012). Karanja trees have been used for soil reclamation around coal mines and revegetation in India (Maiti, 2012).
Soil binder and improver
In India, karanja has been traditionally used by villagers on slopy uplands to bind the soil (Kumar, 2004).
