Nano-Selenium and its Interaction with other Nano-Nutrients in Soil under Stressful Plants: A Mini-Review

The massive application of nanoparticles in many sectors including medicine, agriculture and industry caused the inevitable release into different environmental compartments particularly groundwater and soil. The fate and behavior of these nanoparticles in soil and groundwater and their effects on soil biosystem remain largely unaddressed. Nano-selenium (Se-NPs) has intensive applications nowadays in different agroecosystems, but several studies concerning this behavior in plants and soils carried out in individual case studies. Thus, the interaction of nano-selenium with different other nano-nutrients in soils and their uptake by cultivated plants still need urgent investigations. Based on the interaction is a common feature in the nature. Therefore, there are still also many unanswered questions regarding the interaction of Se-NPs with other nano-nutrients in soil like when these reactions will be synergistic or antagonistic? Which factors can control the bioavailability of nano-Se in soil in presence of other nano-nutrients? What is the expected role of stressful plants in orientation of this interaction among nano-nutrients?
