The heavy silty young marine clay cracks to a depth of 35-40 cm during the dry season. The cation-exchange capacity is 32.5 meq/100g soil for the subsoil and 52.2 meq for the topsoil (due to high humus content). Chemically the soil resembles solonchak, but in profile structure it more closely resembles solonets. Yields of 2, 500 kg/ha shelled rice are normal. The average Cl content of the groundwater (6.4 g/litre) is too high for agriculture. Salinization of the upper 5 cm of topsoil is unexpectedly slight and apparently has no direct relationship to groundwater salinity. With irregular changes in the monsoon the soil may become highly saline while the crop is still standing. (Abstract retrieved from CAB Abstracts by CABI’s permission)
