Abstract:
Nowadays, using innovative nanotechnology for the development of new and improved fertilizers agents is considered to be one of the most promising effective solutions in order to significantly enhance the global agricultural productions needed to meet the demands of an ongoing growing population. Due to this evolution, the need to evaluate the potential risks of these novel fertilizers in order to ensure their safe production, their use, and their disposal is a global concern. In this context, the focus of this study was the development of nano-devices and nano-materials with chemical properties that can be used as natural agriculture systems and natural biochemical substances. Magnetic oxide nanoparticles, FexOy, have been developed and utilized for the improvement of iron content in wheat plants. The plants were cultivated and treated at the soil level with magnetic oxide nanoparticles solutions. After they have reached maturity the plants were harvested and were analyze by optical microscopy, Fourier Transform Infrared Spectroscopy (FT-IR) and Scanning Electron Microscopy (SEM). The optical visualization of the harvested plant revealed the obtaining of a wheat standard plant with no abnormalities or other signs of damage. The harvested plants were dried and calcined. The ashes resulted from the calcination process were investigated by FTIR and SEM. Both FTIR and SEM results evidenced the presence of iron in the investigated samples. The results obtained in this study show the potential of these types of magnetic nanoparticles of being used in agricultural applications.
