Perspectives

Aromatic grasses were found to be promising for phytorernediation of sodic and saline-sodic soils. A relative performance of amelioration with that of chemical amendments highlights the effective role of aromatic grass in amelioration of sodic and saline-sodic soils. Phytorernediation has been found to be beneficial in several aspects: (1) no financial liabilities for chemical amendments, (2) financial benefits from aromatic crops during amelioration, (3) more uniform and greater zotre of amelioration (4) improvement in soil properties and (5) environmental benefits in terms of C sequestration. However, phytorernediation approach is effective only when used on moderately sodic and saline-sodic soils. Moreover, the amelioration process through phytorernediation is very slow and it requires calcite to be present in the soil. So, the feasibility of phytorernediation is limited when soil is highly saline or sodic. Considering the challenge associated with amelioration of sodic and saline-sodic soils and environmental consequences, it is high time to consider the soil as an useful natural resource rather than environmental burden. In this context, phytorernediation through cultivation of aromatic crops is a cost effective intervention for amelioration of these soils. The economic importance of aromatic crops as a candidate for phytorernediation of sodic and saline- sodic soils of resource poor fanners is also realized. So, phytorernediation can be more effective if selected plants have economic value or local utilization at the farm level. However, in future, we need to consider the economic value of improved soils.
