The study looked at how moisture affects the amount of soluble salts in coastal soils from the Sunderban region. When the soil was diluted with water, the soluble salt content increased. However, the total amount of water-soluble and exchangeable bases remained the same. The increase in soluble salts with higher moisture levels was due to chemical reactions. The soils preferred calcium over magnesium. As moisture increased, the levels of exchangeable sodium and magnesium decreased, while exchangeable calcium increased.
