Zero-valent nano iron synthesis and the investigation of the use of zero-valent nano iron as iron fertilizer in plants

In this thesis, zero-valent nano iron was produced by chemical precipitation method using FeCl3 and NaBH4. Dimensional anylisis of the produced zero-valent nano iron particles were carried out with XRD and SEM research. On the other hand, the synthesized zero-valent nano iron particles were applied to the soybean as iron fertilizer against the iron deficiency in plants. Zero-valent nano iron, FeEDDHA and FeSO4.7H2O fertilizers were applied under controlled conditions to soybean at three different doses (0 mg kg-1 – 15 mg kg-1 – 30 mg kg-1). When the results were compared, it was found that the zero-valent nano iron was more effective than the other iron fertilizers, and the 15 mg kg-1 zero-valent nano iron dose was found as the most suitable dose for soybean.
