Effect of elemental sulfur as fertilizer ingredient on the mobilization of iron and phosphorus from a calcareous soil cultivated with durum wheat: Ιnduced assemblage of plant growth promoting arylsulfatase producing bacteria. Plant growth promoting arylsulfatase producing bacteria

The application of fertilizer granules with incorporated elemental sulfur (FBS0) in durum wheat crop produced higher yield compared with that produced by the conventional ones (F), provided that the soils of the experimental fields (F vs FBS0) were of comparable quality. In this experiment, it was examined quite the opposite case, where the FBS0-treatment took place in a soil of profoundly inferior quality compared with the F-treatment’s soil, aiming at possibly alleviating the imbalance.Fertilizers amended with elemental sulfur counteracted effectively the inferior quality of the rhizosoil, by modulating the abundance of plant growth promoting bacterial communities, thus enhancing microbial mediated nutrient mobilization, resulting in improved plant nutritional status.
