(mineralogy)
FePO4·2H2O A pale-red mineral crystallizing in the orthorhombic system, isomorphous with variscite and dimorphous with phosphosiderite, and specific gravity 2.87.

Precipitation of the minerals strengite or variscite would be possible at this site during the study period given the near-neutral pH of soil (6.
It is also possible that phosphate minerals did not form because not enough iron was available for precipitation of variscite, strengite, or vivianite.
Williams and Patrick (1971) observed that crystalline strengite can be rendered soluble under pH 5 by lowering solution redox potential to values less than -200 mV, which are not normally found in submerged conditions.
1973) observed that strengite solubilisation was more pronounced under conditions of low pH combined with low redox potential.
