Summary Damage due to Has occurring in some acidic, heavy paddy soils and peaty fishponds is usually preceded by falls in temperature and atmospheric pressure. The O 2 , content of the water layer increases with the fall in the temperature and, as the redox‐level sinks in the mud, the superficial layer of the mud is oxidized and H 2 SO 4 is formed which releases H 2 S from the sulphide in its environment. The decrease of atmospheric pressure lifts the gases including H 2 S from the hollows of the mud into the water layer and thence into the atmosphere. The gases carry colloidal particles and render the water turbid. The released H 2 S may result in root‐rot and deficiency diseases in the rice plants, and algae bloom and fish death in the ponds.
