“…More efficient approaches for the foliar application of micronutrients to crops on the broadacre scale can be achieved through the production of novel fertilizers and delivery processes. Crop production can benefit from nanoparticle properties due to their initial fast reactivity, sustained slow-release, and surface-coating effects for intervascular transfer to developing tissue ( Gutiérrez et al., 2011 ). Moreover, the use of natural materials to produce nanomaterials that can be used as vehicles for loading and delivering micronutrients to grain could reduce the risk of toxicity in plants.…”

Agronomic biofortification of wheat grain with zinc can improve the condition of about one billion people suffering from zinc (Zn) deficiency. However, with the challenge of cultivating high-yielding wheat varieties in Zn-deficient soils and the global need to produce higher-quality food that nourishes the growing population, innovation in the strategies to deliver Zn directly to plants will come into play. Consequently, existing foliar formulations will need further refinement to maintain the high agronomic productivity required in competitive global grain markets while meeting the dietary Zn intake levels recommended for humans. A new generation of foliar fertilisers that increase the amount of Zn assimilated in wheat plants and the translocation efficiency of Zn from leaves to grains can be a promising solution. Research on the efficacy of adjuvants and emerging nano-transporters relative to conventional Zn forms applied as foliar fertilisers to wheat has expanded rapidly in recent years. This review scopes the range of evidence available in the literature regarding the biofortification of bread wheat (Triticum aestivum L.) resulting from foliar applications of conventional Zn forms, Zn nanoparticles and novel Zn-foliar formulations. We examine the foliar application strategies and the attained final concentration of grain Zn. We propose a conceptual model for the response of grain Zn biofortification of wheat to foliar Zn application rates. This review discusses some physiological aspects of transportation of foliarly applied Zn that need further investigation. Finally, we explore the prospects of engineering foliar nano-formulations that could effectively overcome the physicochemical barrier to delivering Zn to wheat grains.

“…Skipping of gene transfer from foreign organisms allows nanotechnology to consume less time than conventional gene transfer methods (Chinnamuthu & Boopathi, 2009). Nair, Varghese, Nair, Maekawa, Yoshida & Kumar (2010), and Gutiérrez, Mussons, Gatón & Rojo (2011), showed that priming of gene expression and release of genetic material throughout time in plants could be pursued by using properly functionalized nanomaterials loaded with various genes and substances. For example, PEGylated chitosan nanoparticles can control the release of genetic material throughout time (Nair et al, 2010;Gutiérrez, Mussons, Gatón & Rojo, 2011).…”

Nanotechnology advent in agri-food sector is set to prompt next revolution in agricultural engineering. However, there is a perpetually rising need for development of new nanotechnologies that could synchronically work with various agrochemicals such as fertilizers, pesticides, herbicides, and growth promoters to potentially increase farmlands efficiency, preserve agro-ecosystems, and diminish the negative health risks imposed by conventional practices. In nanotechnology, smart delivery systems that utilize either nanoscale carriers such as clay nanotubes and carbon nanotubes or nanoparticles such as mesoporous silica nanoparticles and silver nanoparticles, could enable not only the accurate and targeted delivery of functional ingredients but also their impartial dissemination over farmlands. Nanotechnology has found applications for bioremediation of irrigation water and agricultural runoff, crop breeding, agronomic traits via genetic manipulation of genomes at molecular level, and detection of minute quantities of contaminants and stressors as well as early detection of plant diseases and continuous monitoring of plant environment through employment of nano-biosensors. Scientists are diligently working to explore new substitutes for conventional technologies. Advancements in nanotechnology could help them to explore new frontiers and find novel applications in agri-food sector.Keywords: Agrochemicals; bioremediation; crop breeding; micro-fabricated xylem vessels; smart delivery systems; smart nano-dust.
