If there is an intrusion of sea-water into freshwater aquifers, whether the cat-ion exchange is sufficient to account for the change in water chemistry?
I think that you have to study about SAR in water and ESP in soil (of the surrounding environment) if you wish to study about the impacts on agriculture.
Some time article in the link may also important for your study.

While sea intrusion is recognized as the mixing of sea water into freshwater aquifers. Coastal aquifers are increasingly threaten by sea water intrusion due to increased urbanization, groundwater exploitation, and global sea level rise. Pattern diagrams, which constitute the outcome of several hydro - geochemical processes, have traditionally been used to character vulnerability to sea water intrusion. The cation exchange occurs when equilibrium in the groundwater is disturbed by seawater intrusion. A groundwater quality index for seawater is developed to estimate seawater mixing and water mixing domain. The index is validated with data from worldwide coastal aquifers using GIS spatial analysis. The index constitutes a key indicator in aquifer exploitation to meet growing water demands.
Dear Suresh Kumar Govindarajan , I think that the link below be important for your study.
