Download Solution PDFStatement 1 is correct. Sodic soils are characterized by low electrical conductivity (EC < 4 dS m-1), high pH(>8.2), high Sodium Absorption Ratio (SAR > 13), and high exchangeable sodium percentage. Statement 2 is incorrect. Saline soils in southwestern Punjab result from evaporation enrichment and salt dissolution, not high rainfall.
