Moreover, the assumption that the ferrous iron is only oxidized by oxygen is likely to fail when nitrate is present in appreciable amounts. Scarification by heat, acid treatments, bleach, oxidizing gases and mechanical abrasion are some of the traditional procedures known to elicit germination. Acids and oxidizing agents may weaken layers of tissues surrounding the embryo and allow emergence of the embryo. Consequently, the species losing electrons are virtually oxidized.

Thus, the powerful oxidation reaction would be expected to come to an early end after the fast initial stage, oxidizing only 10 % of the added nutrient organic acids. The precipitation of dolomite from basinal brines rather than meteoric waters further suggests that the dolomite was precipitated at an earlier stage than the haematite, which required oxidizing conditions. In their model, the reducing fluids remove oxidized iron coatings from the sand grains, and later precipitate the iron as spherical concretions when the iron encounters oxidized groundwater. The silty-heterolithic association requires deposition in areas away from the influence of major channels, where extensive sorting and fractionation of finegrained sediments occur under oxidizing conditions. Improvements can be reached through a better treatment concept using different chemicals such as oxidizing agents or considering other areas of potential dosage such as the freshwater system.
