Magnesium adsorption ratio (MAR) defines the relationship between magnesium and calcium concentration in groundwater (Ragunath 1987; Ayuba et al. 2013).
Magnesium adsorption ratio (MAR) causes harmful effect to soil when it exceeds 50 (Gupta and Gupta 1987).
Magnesium adsorption ratio expresses the relationship between calcium and magnesium concentration in surface water (Ayuba et al. 2013).
Sodium adsorption ratio (SAR), magnesium adsorption ratio (MAR), residual sodium bicarbonate (RSC), soluble sodium percentage (Na%), permeability index (PI) and chlorinity index were assessed for irrigation purposes.
The irrigation quality assessment was carried out using EC (μS/cm), SAR (Richards 1954), Kelly ratio (Kelly 1963) and magnesium adsorption ratio (MAR) (Paliwal 1972).

Sodium adsorption ratio (SAR), soluble sodium percentage (Na%), permeability index PI), magnesium adsorption ratio MAR) and salinity hazard are some of the factors to understand the groundwater suitability for agriculture.
To explore the ionic toxicity of the study area, the derived parameters like sodium adsorption ratio, soluble sodium percentage, residual sodium carbonate, magnesium adsorption ratio, Kelly's ratio and permeability index were calculated.
