The impact of oxygen diffusion from plant roots on the soil redox in the root zone in flooded rice bays was investigated using two Australian rice growing soils. The rates of production of Fe(II) and Mn(II) in pore water resulting from the reduction of soil minerals was used to gauge the extent of development of anaerobic conditions and the time taken for equilibrium to establish. Soil concentrations of readily reducible Fe were 13-28 times greater than Mn, making Fe a more reliable indicator… CONTINUE READING
