The interpretation of the sulfur data is fundamentally flawed. The net absorption ratio M_S/M_Mo for MoS₂ NPs (values ~8-15) is chemically impossible if the S originated primarily from the nanofertilizer, as MoS₂ has a fixed mass ratio of ~0.67. These high values indicate the absorbed S came predominantly from background soil sulfate, not the nanomaterial. The claim that MoS₂ acts as a synergistic “two-in-one” Mo and S fertilizer is therefore not supported by the data, invalidating a key conclusion of the study.
