Comparison of the fresh biomasses of the tomato plants grown in soil containing bulk vs. nanoscale fertilizers including (a) bulk FeSO4 vs. Fe3O4 NPs, (b) iron citrate vs. Fe3O4@CA NPs, (c) iron humate vs. Fe3O4@HA NPs, and (d) Fe-EDTA vs. Fe3O4@EDTA NPs. The standard error is indicated by the error bars (n = 3). Different letters indicate differences between treatments (p < 0.05). The concentration of iron fertilizers has been reported based on mg of Fe per Kg of soil
