Hydromorphic soils are evolved by which process

Solution(By Examveda Team)

Hydromorphic soils are characterized by the reduction of localized segregation of iron, owing to the temporary or permanent waterlogging of the soil pores which causes a lack of oxygen over a long period.
Hydromorphic soils are evolved by the process of Gleization. It is a typical pedogenic regime of soil that occurs in a moist or cool and cold climate. The pedogenic regime in the soil formation process results in the development of a Glei in the lower part of the soil profile above the parent material due to poor drainage conditions and where waterlogged conditions prevail and such soils are called hydromorphic soils.
