We standardised growth rate estimates derived from nine root and shoot parameters for plants grown in magnetite tailings and natural topsoil, using crops (eight species) to characterise previously identified plant responses and native plants (40 species) to understand the impact of edaphic conditions on the species pool available for restoration.
Originally we sampled the magnetite solutions using the "volume sam- ple" option of the HIAC PC-320 which would count the number of particles in each size channel in a given amount of solution. We used a method of sampling as much of the total sample as possible to minimize the problem of settling.

Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally-occurring minerals on Earth. Naturally-magnetized pieces of magnetite, called lodestone, will attract small pieces ...
Material and methods 2.1. Characterization of Fe 3 O 4 (magnetite) NPs. ... Plant growth enhancement by magnetite NPs has been reported by several studies. For instance, Pariona et al. (2017) showed that Fe 3 O 4 NPs increased the germination and growth of oak seeds (Quercus macdougallii).
