“…Nanomaterials that are utilized for wheat biofortification can also be classified as (a) Polymeric nanomaterials made up of repeated chains of molecules differing in structure and compositions [ 42 ]; (b) ceramic nanomaterials that are nonmetallic and heat resistant nanomaterials composed of both metallic and nanometallic compounds [ 43 , 44 ]; and (c) metal nanomaterials made up of metallic compounds such as metal oxides, quantum dots, nanogold, nanosilver [ 45 ]. Moreover, these materials can be grouped according to their nutritional benefit to the applied plants, such as (a) micronutrient fertilizers, (b) macronutrient fertilizers, (c) plant growth-stimulating NFs, and (d) nanomaterial-enhanced fertilizers [ 44 ].…”

“…As NPs can be applied in appropriate doses at appropriate timings, these can optimize the use of natural resources allowing “precision farming”. While conventional fertilizers are being applied several times in a growth season by farmers to increase the yield, the controlled release of nutrients from nanofertilizers reduces the number of doses and consequently application costs [ 44 ]. A chemical fertilizer consumption of 22 million tons have been reported in 2015 by USDA [ 96 ].…”

The deficiency of nutrients in food crops is a major issue affecting the health of human beings, mainly in underdeveloped areas. Despite the development in the methods of food fortification, several barriers such as lack of proper regulations and smaller public-private partnerships hinder its successful implementation in society. Consequently, genetic and agronomic biofortification has been suggested as the potential techniques for fortifying the nutrients in diets. However, the time-consuming nature and restricted available diversity in the targeted crop gene pool limit the benefits of genetic biofortification. In agronomic biofortification, organic fertilizers face the problem of prolonged duration of nutrients release and lesser content of minerals; while in inorganic fertilizers, the large-sized fertilizers (greater than 100 nm) suffer from volatilization and leaching losses. The application of nanotechnology in agriculture holds enormous potential to cope with these challenges. The utility of nanomaterials for wheat biofortification gains its importance by supplying the appropriate dose of fertilizer at the appropriate time diminishing the environmental concerns and smoothening the process of nutrient uptake and absorption. Wheat is a major crop whose nano-biofortification can largely handle the issue of malnutrition and nutrients deficiency in human beings. Though several research experiments have been conducted at small levels to see the effects of nano-biofortification on wheat plants, a review article providing an overview of such studies and summarizing the benefits and outcomes of wheat nano-biofortification is still lacking. Although a number of review articles are available on the role of nanotechnology in wheat crop, these are mostly focused on the role of nanoparticles in alleviating biotic and abiotic stress conditions in wheat. None of them focused on the prospects of nanotechnology for wheat biofortification. Hence, in this review for the first time, the current advancement in the employment of different nanotechnology-based approaches for wheat biofortification has been outlined. Different strategies including the supply of nano-based macro- and micronutrients that have shown promising results for wheat improvement have been discussed in detail. Understanding several aspects related to the safe usage of nanomaterials and their future perspectives may enhance their successful utilization in terms of economy and fulfillment of nutritional requirements following wheat nano-biofortification.

“…70% in 2050 as a result of the increasing population [ 5 , 6 ]. It is necessary to ratify innovative and futuristic agri-technologies to achieve global food security with improved plant productivity [ 6 ], because environmental difficulties may arise primarily due to the inefficiency of various farming operations based on conventional fertilization practices [ 7 ]. The nutrient utilization efficiency (NUE) seems to be an important metric for assessing agricultural production and nutrient bioavailability in plants [ 8 , 9 ].…”

“…Fertilizers offer nutrients to optimize crop productivity, usually being applied through soil surface broadcasting or mixed with irrigation, which may cause damage to the atmosphere, water bodies, and the ecosystem [ 10 , 11 , 12 , 13 , 14 ]. Hydroponic techniques are used to grow some crops under greenhouse conditions, at the expense of about 10 times greater water and energy consumption, found to be neither economical nor sustainable [ 7 , 15 , 16 ]; the addition of fertilizers can cause eutrophication and ground water contamination, which may badly impact public health [ 17 , 18 ].…”

“…In such a scenario, newer agricultural interventions need to be implemented to fulfill the desire of our global food system [ 7 ] along with the safety of ecosystems, biodiversity, and the climate [ 12 , 13 ], as fertilizer use is proposed to be nearly 20% less by 2030 [ 19 ] through best farming practices to ensure approx. 85% of global agricultural production in the next 10 years [ 20 , 21 ].…”

Recent Trends in Nano-Fertilizers for Sustainable Agriculture under Climate Change for Global Food Security

et al. 2022

Nano-fertilizers (NFs) significantly improve soil quality and plant growth performance and enhance crop production with quality fruits/grains. The management of macro-micronutrients is a big task globally, as it relies predominantly on synthetic chemical fertilizers which may not be environmentally friendly for human beings and may be expensive for farmers. NFs may enhance nutrient uptake and plant production by regulating the availability of fertilizers in the rhizosphere; extend stress resistance by improving nutritional capacity; and increase plant defense mechanisms. They may also substitute for synthetic fertilizers for sustainable agriculture, being found more suitable for stimulation of plant development. They are associated with mitigating environmental stresses and enhancing tolerance abilities under adverse atmospheric eco-variables. Recent trends in NFs explored relevant agri-technology to fill the gaps and assure long-term beneficial agriculture strategies to safeguard food security globally. Accordingly, nanoparticles are emerging as a cutting-edge agri-technology for agri-improvement in the near future. Interestingly, they do confer stress resistance capabilities to crop plants. The effective and appropriate mechanisms are revealed in this article to update researchers widely.
