SEM–EDS microstructural characterization of peat soil used for incubation of sulfur-bearing silicate–phosphate glass fertilizers

The investigated materials were glasses from the multicomponent SiO2–P2O5–K2O–MgO–CaO–SO3 system, designed as potential slow-release carriers of plant-essential nutrients. The dataset documents the microstructural features of the peat granules and the local chemical composition at selected points on the soil samples.

The data support the interpretation of soil–glass alteration processes occurring during incubation experiments and complement the results discussed in the associated scientific publication.
