Hydromorphic soils are evolved by which process

✏️Gleization is the process that dominates in such environments. It involves:
-The reduction of iron due to anaerobic conditions (lack of oxygen)
-This leads to the characteristic gray or bluish-grey colors and mottling patterns observed in hydromorphic soils

📌 Other Options Explanations:
-(a) Calcification
-Calcification is the process of calcium carbonate accumulation in the soil profile. It is associated with arid and semi-arid regions with high evapotranspiration rates, leading to the upward movement and precipitation of calcium carbonate.
-(c) Salinization
-Salinization is the accumulation of soluble salts in the soil, often due to high evaporation rates or poor drainage in arid and coastal regions. It results in the formation of saline soils.
-(d) Solonization
-Solonization is a specific type of salinization process that involves the accumulation of sodium salts in the soil. It leads to the formation of sodic soils with poor structure and drainage.
