2.2.2. Marine Group
In the Marine group, the soils are developed from marine sand. Some subgroups
such as beach ridge complex and swale/lagoon are formed between the
sandbanks. In sandbank area Udipsaments (sandy soils) were formed and used for
coconut garden and the finer sandy soils were used for settlements, home garden
and vegetables.
Inundated swale is dominated by Hydraquents (locally peaty) which were
utilized for rice fields. In the swampy coastal areas and inundated tidal land,
Hydraquents, Sulfaquents, Endoaquepts, and Fluvaquepts are formed. In the estuary
plain, Fluvaquents and Halaquepts dominated. The swampy areas were covered by
swampy forest and shrubs, mangrove and locally used for coastal fish ponds or tidal
rice fields. In the upper part of coastal areas, coarse materials (sand or sandy) cover
the land with the main soil of Udipsamments and Eutrudepts.
