“…the N cycle), because some of the ascending taxa (Bradyrhizobium, and Mesorhizobium) and some of the declining taxa (Armatimonadetes and Chloroflexi) which contain ammonia−/nitriteoxidizing bacteria, anammox bacteria, and denitrifying bacteria, are both reported to be involved in nitrogen fixation, nitrogen removal or in the (de)nitrification process (Li, 2017). In other words, stimulatory and inhibitory actions of MNPs against microbial processes can also be advantages to control nitrogen losses and production of greenhouse gases from soils (Achari and Kowshik, 2018;Gilbertson et al, 2020). For fungi, the relative abundance of the class Archaeorhizomycetes, the order Archaeorhizomycetales, the family Archaeorhizomycetaceae, and the genus Archaeorhizomyces decreased significantly at elevated CuO NPs concentrations.…”

“…Over the past decade, food insecurity and poverty problems still exist especially in many developing countries despite the fact that tremendous progress has been made in increasing agricultural productivity. One of the promising innovative techniques in agriculture is the application of nanomaterials (FAO/WHO, 2010) in the form of fertilizer or as a pesticide developed on the basis of metal oxides nanoparticles (MNPs) (Asadishad et al, 2018) to achieve higher yields with fewer inputs and less nutrient runoff (Gilbertson et al, 2020). For instance, the addition of TiO 2 NPs, ZnO NPs and CuO NPs has been found to increase the growth and yield of crops probably by stimulating photosynthesis and respiration of plants (Adhikari et al, 2016) or by suppressing the growth of soil pathogens (Rizwan et al, 2017).…”

With the expanding nanotechnology, nanoparticles (NPs) embedded products are used in the agricultural sector to improve soil fertility. Thus, two typical metal oxides NPs and their mixtures were applied in different doses to evaluate the impacts on soil microbes. CuO and ZnO NPs boosted soil microbial communities as reflected by the increased number of extractable bacterial or fungal groups and the enlarged values of Chao 1, ACE, and Shannon indices. Relative abundance of some susceptible taxa such as Sphingomonadales increased with increasing concentrations of ZnO NPs, while IMCC26256 decreased with increasing concentrations of CuO NPs. The mixture of CuO and ZnO NPs did not show more promotional effects on the soil bacterial community than the sum of individual effects. Increased soil organic carbon mitigated the impacts on soil bacteria for CuO NPs, but not for ZnO NPs. As micro-nutrients, the ions released from CuO and ZnO NPs had the potential to promote soil microbial community richness and diversity. However, the positive impacts of MNPs were impaired at dosage higher than 250 mg kg −1 soil (213.08 mg kg −1 soil of Cu, 162.73 mg kg −1 soil of Zn). Thus, the application dose and soil type other than the coexistence of MNPs should be considered before the wide use in increasing agricultural productivity.

“…The advantages of nanotechnology need to be compared to other biofortification procedures that may provide long-term and cost-effective solutions, including plant breeding and CRISPR/transgenic technology [ 111 ]. In addition to assessing the overall environmental implications, it is important to determine if nano-based solutions are practical compared to conventional practices [ 112 ]. Nanomaterials continue to be manufactured in larger scales, which lead to further decreases in production costs.…”

The global community decided in 2015 to improve people’s lives by 2030 by setting 17 global goals for sustainable development. The second goal of this community was to end hunger. Plant seeds are an essential input in agriculture; however, during their developmental stages, seeds can be negatively affected by environmental stresses, which can adversely affect seed vigor, seedling establishment, and crop production. Seeds resistant to high salinity, droughts and climate change can result in higher crop yield. The major findings suggested in this review refer nanopriming as an emerging seed technology towards sustainable food amid growing demand with the increasing world population. This novel growing technology could influence the crop yield and ensure the quality and safety of seeds, in a sustainable way. When nanoprimed seeds are germinated, they undergo a series of synergistic events as a result of enhanced metabolism: modulating biochemical signaling pathways, trigger hormone secretion, reduce reactive oxygen species leading to improved disease resistance. In addition to providing an overview of the challenges and limitations of seed nanopriming technology, this review also describes some of the emerging nano-seed priming methods for sustainable agriculture, and other technological developments using cold plasma technology and machine learning.

“…Potential applications of engineered nanomaterials in agriculture include, but are not limited to, nanofertilizers [8,27,28], nanopesticides [8,29], nano-enabled agrochemical carriers [30,31] and nanosensors [32][33][34]. Selected engineered nanomaterials have been applied as soil amendments, seed coatings, and foliar sprays [35,36]. To meet the goal of controlled release and delivery of active ingredients with reasonable environmental cost and energy input, nanomaterials need to be carefully designed and applied by sustainable methods [23,35,37].…”

Nanoscale hydroxyapatite (nHA) was synthesized to investigate its potential as a phosphorus (P) ensembled nanofertilizer, using soybean (Glycine max L.) as a model plant. The conventional analogue phosphate (pi) was used for comparison with the synthesized nHA. Varied precipitation intensities (0%, 30%, 60%, and 100%) were simulated by adding selected volumes of the P fertilizers (nHA or pi) via foliar spray and soil amendment. The total amounts of added P were the same across all the treatments. The importance of a wash-off effect was investigated on foliar-treated seedlings by evaluating different watering heights (20, 120, and 240 cm above the seedlings). Fresh weight, pigment content, macro-, and micronutrient contents were measured in soybean tissues across all the treatments after 4 weeks of greenhouse cultivation. The synthesized nHA showed superior effects on plant nutrient content upon high precipitation intensities. For example, at 100% precipitation intensity, there was 32.6% more P and 33.2% more Ca in shoots, 40.6% more P and 45.4% more Ca in roots, and 37.9% more P and 82.3% more Ca in pods, as compared to those with pi treatment, respectively. No impact on soybean biomass was evident upon the application of nHA or pi. Further investigation into customizing nHA to enhance its affinity with crop leaves and to extend retention time on the leaf surface is warranted given that the present study did not show significant positive impacts of nHA on soybean growth under the effects of precipitation. Taken together, our findings increase understanding of the potential application of nHA as a nano-enabled fertilizer in sustainable agriculture.
