“…27,28 Moreover, the high capability to be doped with foreign ions or molecules (e.g., K + , Mg 2+ , Zn 2+ , CO 3 2-, NO 3 -, urea, etc), and tuneable solubility make them as the ideal nanoplatform to provide a sustained delivery of multinutrients upon nanoparticle dissolution. [29][30][31] In fact, several works in agrochemical field demonstrated the potential of ACP and Ap nanoparticles for the controlled delivery of plant macronutrients, such as phosphorous [32][33][34][35][36][37][38] and nitrogen. 29,30,[39][40][41][42] Synthetic Ap nanoparticles have been also functionalized with humic subtances (HS) providing the synergistic co-release of crop nutrients and stimulants.…”

“…The treatments were introduced when plants were 14 days old and stopped when the plants were 45 days. The solutions were sonicated for 30 min at 45/65 kHz using a GT SONIC-L3 sonicator before application [ 19 ] to disperse NPs agglomerates by generating evacuated cavities or microvoids in the liquid. This exerted a shear force on NP agglomerates, effectively overcoming the van der Waals force that holds them together [ 56 ].…”

“…The previously published work on the effect of macronutrients (i.e., hydroxyapatite nanoparticles (HANPs)) on Raphanus sativus (radish) with respect to seedling growth and two plant metabolites, serves as the foundational bedrock upon which the current study was built [ 19 ]. The insights and discoveries obtained from our earlier research, where a concentration of 10,000 mg/L of raw HANPs had no toxic effects on R. sativus, [ 19 ] have laid a solid groundwork, providing essential context and understanding to investigate how a micronutrient (i.e., ZnO NPs at high doses) could affect R. sativus . Despite the limited commercial utilization of ZnO NPs thus far, there is a concern that once widespread adoption occurs, there may be an excessive release of these nanoparticles.…”

The escalating release of zinc oxide nanoparticles (ZnO NPs) into the environment poses a substantial threat, potentially leading to increased concentrations of zinc (Zn) in the soil and subsequent phytotoxic effects. This study aimed to assess the effects of ZnO NPs on Raphanus sativus (R. sativus) concerning its tolerance levels, toxicity, and accumulation. ZnO NPs were synthesized by the wet chemical method and characterized by powder X-ray diffraction (PXRD), Fourier-transform infrared (FTIR) spectroscopy, ultraviolet–visible (UV–vis) spectroscopy, dynamic light scattering (DLS), and scanning electron microscopy (SEM). The effect of ZnO NPs (70 nm) on R. sativus grown in coir was evaluated. The application of 1,000 mg/L of ZnO NPs resulted in a significant increase (p < 0.05) in soluble protein content, carbohydrates, chlorophyll a (Chl-a), chlorophyll b (Chl-b), total chlorophylls, carotenoids, and antioxidants by 24.7%, 58.5%, 38.0%, 42.2%, 39.9%, 11.2%, and 7.7%, respectively. Interestingly, this dose had no impact on the indole acetic acid (IAA) content. Conversely, the use of 2,000 mg/L of ZnO NPs in the same medium led to a significant reduction (p < 0.05) in soluble protein content by 23.1%, accompanied by a notable increase in IAA by 31.1%, indicating potential toxicity. The use of atomic absorption spectroscopy confirmed the internalization of zinc in seedlings, with a statistically significant increase (p < 0.05). In control plants without ZnO NPs, Zn concentration was 0.36 mg/g, while at the highest ZnO NPs tested dose of 10,000 mg/L, it significantly rose to 1.76 mg/g, causing leaf chlorosis and stunted seedling growth. This suggests potential health risks related to Zn toxicity for consumers. Given the adverse effects on R. sativus at concentrations above 1000 mg/L, caution is advised in the application and release of ZnO NPs, highlighting the importance of responsible practices to mitigate harm to plant life and consumer health. The study demonstrated the tolerance of R. sativus to high Zn levels, classifying it as a Zn-tolerant species.

“…Pristine HANPs were shown as an alternative for conventional phosphorus fertilizers (Liu and Lal, 2014;Madanayake et al, 2021). Recently, pot tests using multifunctional phosphorus NFs (PNFs) containing humic substances and HANPs showed improved plant growth and productivity in corn.…”

Agricultural development has become a requisite to meet the food security of an increasing world population under changing climate for eliminating poverty and hunger. Recently, scientists recognized that human wellness and healthy life are going to face challenges in the near future because of the vulnerability of agriculture and nat-ural resources. It is due to imbalance and unnecessary use of synthetic agricultural inputs in traditional farming systems. Therefore, improved agricultural technology has to ensure, in traditional farming, safe agricultural produce and bringing down of environmental pollution. Recently, nanotechnology (NT) has been recognized as a promising next-generation technology in the field of agriculture. As an environment-friendly and economically viable tool, the potentiality of nanomaterials (NMs), such as nanosensors, nanopesticides, nanofertilizers, nanocarriers, nanochips, and nano-packaging, has shown great prospect in improving safe agricultural productivity and upholding of environmental safety. Because the use of NMs decreases imbalance and unconscious utilization of synthetic fertilizers and pesticides, this minimizes the loss of nutrients and lead to improved agricultural productivity thru the smooth distribution of fertilizers and pesticides, and also improving water and nutrient effi-ciency. The current review concentrates on the utilization of NT for agricultural sustainability and environmental safety.
