I recall organic germanium sesquioxide from the Japanese researcher K.
Orton (1874) noted that "the brown color for which it [the Buena Vista] is so justly admired is not a natural, but a derivative color, formed from the conversion of a notable quantity of protoxide of iron [Fe[O.sub.2] into sesquioxide [[Fe.sub.2][O.sub.3]]."
The particles of humus coat the sesquioxide and, thus, the phosphates become protected and this coating can prevent the fixation of the P in the soil (Tisdale & Nelson, 1966).
The soil consists of a concretion of iron sesquioxide forming hard substrates that are partially penetrable by plants (Antonini et al., 2005; Rosiere and Chemale, 2000).
