G. Bourrie et al., 2 TYPES OF SEASONAL-VARIATIONS OF DISSOLV ED IRON IN HYDROMORPHIC SOILS UNDER TEMPERATE CLIMATE, Comptes rendus de l'Academie des sciences. Serie 2, Mecanique, physique, chimie, sciences de l'univers, sciences de la terre, 318(1), 1994, pp. 87-92
Seasonal variations of dissolved iron follow two distinct patterns: th
e first is classically dependent on the level of the water table, iron
being mobilized when this level is high and reprecipitating as it low
ers; the second is original and dependent on lateral input of oxygen f
rom upslope, iron remaining immobile while this input persists and bec
oming mobilized as it stops and the environment becomes confined.
