This soil turns shallow during the monsoon, with clay content reaching nearly 40% to 50% all throughout the profile. In level land or depression, a slicken side along with the wedge shaped aggregates absorb the soil. This soil turns bonding during the summer season and remains the same during monsoon. The soil also has a good fertility status. The minerals found in this type of soil are smectite, hydrous mica, kaolonite and chloride. The structure of sediments deposited in this soil eventually turns finer.These are generally layers of sand at different department which do not go deeper than 40 to 60 cm of surface level due to the changing course of the current.
