“…The TGA analysis showed three decomposition stages in the nanoformulations, similar to those reported by Kameda et al (2010) and Bianco et al (2009). Particle size analysis according to DLS and SEM micrographs (Figure S3) showed that the dimension of the nanostructures in all the nanoformulations was within the range reported for other nanomaterials as in Meier et al (2020) and Bianco et al (2009).…”

Increasing rates of nitrogen (N) conventional fertilizer have led to increasing risks of N losses to the atmosphere, mainly as ammonia (NH3) and nitrous oxide (N2O). The aim of this study was to evaluate the effect of foliar N-based nanoformulations on the dynamics of N2O and NH3 emissions from grasslands. Six N treatments (50 kg N ha−1) plus a control (n = 4) were tested on a completely randomized design: granular urea (Urea-g), dissolved urea (Urea-d), dissolved ammonium nitrate (NH4NO3), and nitrate-, urea-, and ammonium-based nanoformulations (NO3-F, Urea-F, NH4-F) applied as foliar spray to intact soil cores maintained under controlled conditions. In addition, a control N = 0 was included. Cumulative emissions of N2O and NH3 (mg N m−2) were measured using dynamic/static chambers. Effects on yield and soil available N were also quantified. Volatilization of NH3 was the main N loss pathway (ranged from 2 to 51% of the N applied). Higher emissions were observed with NH4-F and low emissions in the nitrate-based fertilizers. Direct N2O losses were low compared to NH3 losses, varying between 0.07 and 0.25% of the N applied. Due to high NH3 losses, indirect N2O losses were 0.3 to 2.8 times greater than direct N2O losses. There was no effect of N treatments on soil available N or pasture yield. The application of a NO3-foliar formulation emerges as a potential alternative for the mitigation of integrated N gaseous emissions. Ammonium-based nanoformulations require improvements in order to reduce losses. Further studies should include yield evaluations under field conditions, cost–benefit analysis, and potential impacts in the agri-food chain.

“…NPs can be employed in several ways aiming to reduce soil pollution, like remediation processes to diminish the employment of pollutant products [142]. Applying nanotechnology to fertilizers, herbicides, pesticides or growth promoters can lead to important benefits by reducing the required amount of these compounds and enhancing their activity [143]. In this way, the dose needed to achieve the effect is lowered as well as the consequent side effects and pollutant release to the environment and, therefore, the energy that would be consumed to carry out later soil treatments.…”

The unique properties that nanoparticles exhibit, due to their small size, are the principal reason for their numerous applications, but at the same time, this might be a massive menace to the environment. The number of studies that assess the possible ecotoxicity of nanomaterials has been increasing over the last decade to determine if, despite the positive aspects, they should be considered a potential health risk. To evaluate their potential toxicity, models are used in all types of organisms, from unicellular bacteria to complex animal species. In order to better understand the environmental consequences of nanotechnology, this literature review aims to describe and classify nanoparticles, evaluating their life cycle, their environmental releasing capacity and the type of impact, particularly on living beings, highlighting the need to develop more severe and detailed legislation. Due to their diversity, nanoparticles will be discussed in generic terms focusing on the impact of a great variety of them, highlighting the most interesting ones for the industry.

“…Micronutrients such as iron (Fe), boron (B), manganese (Mn), copper (Cu), zinc (Zn) and molybdenum (Mo) have also been enclosed in nanomaterials such as chitosan, zinc oxide NPs (ZnO NPs), Cu NPs and Ca NPs, which improve the effective accessibility of micronutrients to plants [ 6 , 23 , 24 , 25 ]. These micronutrients play crucial roles in diverse plant physiological and chemical reactions, including photosynthesis, enzyme components and enzyme activators.…”

“…These micronutrients play crucial roles in diverse plant physiological and chemical reactions, including photosynthesis, enzyme components and enzyme activators. Moreover, the application of nanofertilizers made of micronutrients promotes plant growth and increases yields [ 24 , 25 ]. For example, ZnO NPs fertilization of strawberry significantly increased fruit setting and the grain yield compared to strawberry fertilized with zinc sulfate (ZnSO 4 ) [ 24 ].…”

“…B deficiency damages shoot growth and pollen germination. However, foliar application of calcium borate NPs (CaO 2 B 2 O 3 ·10H 2 O NPs) to lettuce promoted the accumulation of B 1.54-fold and 3.95-fold in shoots and roots, respectively, compared with treatment using a nutrient solution in traditional B addition [ 25 ]. As mentioned above, extra fertilizing micronutrients can enhance the photosynthesis rate and antioxidant enzyme activity.…”

With the frequent occurrence of extreme climate, global agriculture is confronted with unprecedented challenges, including increased food demand and a decline in crop production. Nanotechnology is a promising way to boost crop production, enhance crop tolerance and decrease the environmental pollution. In this review, we summarize the recent findings regarding innovative nanotechnology in crop production, which could help us respond to agricultural challenges. Nanotechnology, which involves the use of nanomaterials as carriers, has a number of diverse applications in plant growth and crop production, including in nanofertilizers, nanopesticides, nanosensors and nanobiotechnology. The unique structures of nanomaterials such as high specific surface area, centralized distribution size and excellent biocompatibility facilitate the efficacy and stability of agro-chemicals. Besides, using appropriate nanomaterials in plant growth stages or stress conditions effectively promote plant growth and increase tolerance to stresses. Moreover, emerging nanotools and nanobiotechnology provide a new platform to monitor and modify crops at the molecular level.
