Geric qualifier (gr): in some layer at <= 100 cm, the effective exchange complex (sum of bases + 1 N KCl Al-exchangeable) does not exceed 1.5 cmol+/kg fine earth, OR the soil shows net positive charge (delta pH = pH_KCl - pH_H2O > 0). The "or" path makes Geric / Posic overlap by design (per WRB Ch 5).
