“…Numerous categories of nano-fertilizers have been employed, and various nanoparticles have previously been advocated for use in agriculture. There are several different encapsulation techniques, such as encasing nutrients with a thin protective covering of polymer, coating nutrients with nano-materials like nanotubes, and formulations that can offer nutrients as nano-scale emulsions [118]. There is advancement in the use of urea-coated hydroxyapatite by employing it as a nano-fertilizer [119].…”

Nanotechnology has attracted remarkable attention due to its unique features and potential uses in multiple domains. Nanotechnology is a novel strategy to boost production from agriculture along with superior efficiency, ecological security, biological safety, and monetary security. Modern farming processes increasingly rely on environmentally sustainable techniques, providing substitutes for conventional fertilizers and pesticides. The drawbacks inherent in traditional agriculture can be addressed with the implementation of nanotechnology. Nanotechnology can uplift the global economy, so it becomes essential to explore the application of nanoparticles in agriculture. In-depth descriptions of the microbial synthesis of nanoparticles, the site and mode of action of nanoparticles in living cells and plants, the synthesis of nano-fertilizers and their effects on nutrient enhancement, the alleviation of abiotic stresses and plant diseases, and the interplay of nanoparticles with the metabolic processes of both plants and microbes are featured in this review. The antimicrobial activity, ROS-induced toxicity to cells, genetic damage, and growth promotion of plants are among the most often described mechanisms of operation of nanoparticles. The size, shape, and dosage of nanoparticles determine their ability to respond. Nevertheless, the mode of action of nano-enabled agri-chemicals has not been fully elucidated. The information provided in our review paper serves as an essential viewpoint when assessing the constraints and potential applications of employing nanomaterials in place of traditional fertilizers.

“…Due to nutritional deficiencies, the quality of produce and the overall yield of crops will be reduced. The extent of multi-nutrient deficiencies is increasing day by day, leading to crop losses of nearly 25–30% . To correct these nutritional deficiencies, farmers are applying large commercial fertilizers, leading to disturbance in the soil mineral balance and fertility and also creating environmental concerns.…”

“…Nanoparticles (NPs) interact at the molecular level in living cells, and employing nanoparticles in agriculture could impart some beneficial effects in seed germination and the control of plant diseases . Using NPs and nanopowders as carriers, controlled or delayed-release fertilizers have been developed. , NPs are highly reactive due to their specific surface area, high-density reactive areas, or increased reactivity on the particle surfaces.…”

“…The extent of multi-nutrient deficiencies is increasing day by day, leading to crop losses of nearly 25–30%. 1 To correct these nutritional deficiencies, farmers are applying large commercial fertilizers, leading to disturbance in the soil mineral balance and fertility and also creating environmental concerns. However, the real potential of fertilizers being applied remains unutilized primarily due to bottlenecks of leaching, runoff, fixation, and reactivity in the soil, leading to lower plant use efficiency.…”

Fe and Zn Metal Nanocitrates as Plant Nutrients through Soil Application

Nanocitrates of iron (Fe) and zinc (Zn) in the form of plant nanonutrients were examined for their behavior in soil and the uptake of these by 20-day old groundnut (Arachis hypogaea) seedlings under greenhouse conditions. The Fe (0.04 to 0.008 mmol/kg of soil) and Zn (0.02 to 0.004 mmol/kg of soil) nanocitrates were applied to soil and compared with commercial counterparts (FeSO 4 , ZnSO 4 , nano-Fe, nano-Zn, Fe-EDTA, Zn-EDTA). The combined nanocitrate compositions were also formulated by physical means and characterized. The plant uptake of Fe and Zn was determined through atomic absorption spectrometry (AAS). All the treated plants showed good germination and higher vigor indexes compared to the control treatments. The highest available Fe and Zn soil contents after leaching were 150.5 and 18.9 mg/kg, respectively, in combined nanocitrate compositions, whereas in the control (untreated) soil, the Fe and Zn contents were 6.0 and 0.7 mg/kg, respectively. The plant's Fe content was 0.48 mg/pot for the combined nanocitrate composition, and that of the untreated plant sample was 0.02 mg/pot. The plant's Zn content was 82.3 μg/pot for pure zinc citrate, and the respective untreated-plant Zn content was 2.1 μg/pot. These values are better than those observed for commercial fertilizers. Additionally, no trend in promotional and antagonistic correlations between Fe and Zn in combined nanocitrates was observed in the studied period (20 days in duration). Among the 34 synthesized citrates, six nanocitrates show promising trends for evaluation under field conditions with higher stability.

“…Additionally, increasing salinization harnesses the agricultural pro t and economic loss to farmers along with depletion of natural resources of fertilizers. Nanotechnology has been in use for agricultural sustainability through development of controlled and slow release techniques with targeted delivery of fertilizers or pesticides for plant nutrition and pest control and lower down the environmental impact [11,12]. For coming generations, nano-fertilizer could be a viable option that might substitute the N usage due to their small size, high surface area-volume ratio, controlled delivery, easy absorption and high reactivity [13,14].…”

Background Sustainable crop production along with best nutrient use efficiency is the key indicator of smart agriculture. Under abiotic stress conditions, nutrient uptake and translocation are restricted affecting plant growth and yield. The combined effect of nano-nitrogen and salt stress are very limited. Recent developments in slow releasing, nano-fertilizers in agriculture, begins a new era for sustainable use and management of natural resources. The aim of the study was to explore whether substitution with nano-urea could mitigate the detrimental effects of salt stress on plant growth and development along with physiological traits. Results With the onset of nano-formulations, this study was designed to explore the potential of nano-nitrogen by replacing traditional urea applications in 33, 50 and 60% doses on rice plant growth and development. Further, the strategic substitutions were compared in saline and sodic soils along with normal soils to dissect the beneficial response of nano-N in two rice varieties under saline stress of ECe ~ 6.0 dSm− 1 and sodic stress of pH ~ 9.1. With saline and sodic stresses, plant RWC decreased by 10.33% and total chlorophyll content by 1.32–1.52%, gas exchange attributes by 10.42–38.8%, leaf area upto 29.9% and yield upto 3.92%, respectively. Leaf greenness (SPAD index) was significantly higher with Nano-N along with number of grains/panicle, crop growth rate and net assimilation rate. Results depicted superiority of nitrogen replacement through nano-N with 0.2–1.64% enhancement in growth traits, 0.93–1.85% in physiological traits, and 1.92% in yield over 100% recommended dose of urea on cumulative basis in rice. Between varieties, salt tolerant rice variety, CSR-10 performed better than Pusa 1121 in terms of morphological, physiological and yield traits under stress conditions and nitrogen substitutions. Conclusions Overall, our experimental findings depicted promising potential of nano-N for enhancing the physiological growth and yield under salt stress and also optimizing better yield in normal soils with 33% replacement of conventional urea.
