S Salinity laboratory diagram [11] (Figs 4a and 4b) based on sodium Adsorption Ratio (SAR) vis a vis specific conductance values, the two most significant parameters of sodium and salinity hazards indicate suitability for agricultural purposes.
Concentration of ionic species ([micro]mol/L) and sodium adsorption ratio (SAR) of the artificial rainwater (AR), leached fertiliser (LF), and gypsum + LF solutions applied during the column experiments Ionic species: N[O.
The main quality criteria for effluent irrigation are the normal chemical requirements for crop irrigation that apply to any irrigation water (salt content, sodium adsorption ratio, sodium, chloride, trace elements, nitrogen, and bicarbonate; Ayers and Westcot, 1985; Baler and Fryer, 1973; Bouwer and Idelovitch, 1987).
Sodium adsorption ratio (SAR) and exchangeable sodium percentage (ESP) are currently used as indices for assessing soil structural stability on interaction with water.
The important parameters affecting the suitability of groundwater for irrigation purposes are: total dissolved solids (TDS), electrical conductivity (EC), sodium adsorption ratio (RSC), sodium percentages (Na%).
The sodium adsorption ratio (SAR) of wastewater is often used as an indicator of the sodicity risk.
G] is the Gapon constant and the square brackets indicate concentrations (in mmole/litre or mmol/L) of the ions in solution, ESR is the exchangeable sodium ratio and SAR is sodium adsorption ratio.
Suitability of groundwater for Irrigation was also carried out based on Total Dissolved Solids, Electrical conductivity, Sulfates, Chlorides, (Table: 2) Sodium Adsorption Ratio and USSL Classification.
Concerns over the environmental problems of highly saline effluent and high sodium adsorption ratios from RCF plants and paper mills has meant that paper mills need to find alternative strategies to reduce the problem, One solution is to reduce the amount of sodium hydroxide used or replace it with an alternative alkali such as magnesium oxide.
