Direct determination of the differentiation process of the oxidized and reduced soil layers in paddy fields



Direct determination of the differentiation process of the oxidized and reduced soil layers in paddy fields



JARQ [Japan Agricultural Research Quarterly] 19(3): 172-177



The redox potential of an ill drained paddy field was studied just below the soil-water interface and at 5 cm depth over a period of 100 days, when the soils were drained. The soil-water interface remained above +200 mV for 50 days before showing a gradual decline to below OmV after 100 days. At 5 cm depth redox potential dropped rapidly below OmV following irrigation. Drainage led to a rapid increase to greater than 400 mV.
