Nanotechnology in Agriculture- Focus on Fertilizers

Nanotechnology is the exploitation of materials at the nano scale (1-100 nm in any dimension). The high bioreactivity of nanomaterials (or nanoparticles) has led to the potential for their application in a variety of systems, including agriculture and food. Although exposure of food crops to nano-scale nutrient elements at high doses has produced dramatic negative responses, evidence has since mounted that at the right, usually low, doses and environmental condition, nanoparticles of nutrient elements have beneficial effects, with the potential to be used as fertilizers to address multiple crop productivity parameters, including growth promotion, yield enhancement, crop health stimulation, nutrient agronomic fortification, and nutrient management. These benefits, therefore, warrant the development of nano-scale fertilizers to enhance the use efficiency of nutrients by crops, thereby mitigating the undesirable fertilizer effects in the environment. Whereas sufficient evidence exist to motivate industry investment in the technology, nanofertilizer as a concept is still at the early developmental stages, and several concerns remain, such as inadequate field-based studies, type of nanofertilizers (encapsulated or naked; nano-enabled bulk fertilizers) to produce, how to efficiently and effectively apply nanofertilizers at field scale (powder broadcasting, suspension application, seed coating, foliar or soil placement), and the lack of adequate understanding of the fate of intact nanoparticles taken up by plants - considering that plants, after all, need the ions, not the particles. Nevertheless, it is anticipated that the development of cost-effective nanotechnologies that are non-disruptive to existing bulk fertilizer production processes are likely to be favored by the fertilizer industry, allowing the incorporation of nanofertilizers into current fertilization regimes for sustainable and qualitative food crop production. This presentation highlights the rationale for developing nanofertilizers, types of nanofertilizers and relevant nutrients, and the fate and effects observed with nanomaterials in plant-soil systems. Perspectives for scaling and commercialization of nanofertilizers are also presented.
