Effect of salinity and biochar on (A) shoot Ca²⁺ (mg⁻¹ g D.W), (B) root Ca²⁺ (mg⁻¹ g D.W) (C) shoot K⁺ (mg⁻¹ g D.W), (D) root K⁺ (mg⁻¹ g D.W), (E) shoot Na⁺ (mg⁻¹ g D.W), (F) and root Na⁺ (mg⁻¹ g D.W), of pea. Error bars above means specify the ± SE of three replicates. Same letter sharing by means for a parameter do not vary significantly at p ≤ 0.05. V1 = Meteor; V2 = Green Grass; Control = No salinity; Salinity = 80 mM Nacl; Control = No Biochar; BC (55 g) = Biochar 8 g/kg soil; BC (110 g) = Biochar 16 g/kg soil.
