Nano-Biofertilizers Synthesis and Applications in Agroecosystems

Abstract

Green chemistry and nanobiotechnology have great potential for generating new and significant products that are favorable to the environment, industry, and consumers. The nanoforms of metals and nanocomposites are more effective and efficient agents than their bulkier counterparts because of their distinctive physical, chemical, and optical properties. Green technology is a rapidly growing scientific field that has recently received attention due to its many applications. Different nanoparticle dimensions, sizes, and bioactivities will develop as a consequence of changes in the biomaterials employed for synthesis. The existing understanding of several green synthesis methods, that depend on different plant components and microorganisms for the production of nanoparticles, is summarized in the current review. Employing these materials minimizes synthesis costs while minimizing the use of hazardous chemicals and promoting “biosynthesis.” To produce metal nanoparticles efficiently, bio-reduction is influenced by the abundance of essential enzymes, proteins, and biomolecules. Rapid biosynthetic regeneration makes this characteristic sufficient for their employment in a range of situations. In this review, we explore the biosynthesis of nanomaterials and their potential in sustainable agriculture. Biosynthesized nanofertilizers, or bionanofertilizers, are a revolutionary new class of fertilizer that has been developed with the help of nanotechnology. These fertilizers offer many advantages over traditional fertilization methods and can be used to increase crop yields while reducing the environmental impact of fertilizers. Bionanofertilizer are an inexpensive way to increase plant growth and production, and to improve the use of nutrients by plants and the health of the soil. According to our survey, nanotechnology presents a wide range of prospects by offering a cutting-edge and environmentally friendly alternative in the agricultural sector.

Effect of the pre-magnetic treatment of seeds and the N-fertilizer on the yield and quality of groundnut grown in sandy soil

“…However, the combination between the MT of the seeds and the N-fertilizer significantly increased the N availability in soil and uptake by groundnut seeds. The interactive significant effect of the MT of the seeds and the N-fertilizer is strongly reflected in the estimated yield and yield parameters in tables 4 and 5 (El-Basioni et al (2015), Hafeez et al (2023), Bairwa et al (2023), Altalib et al (2022), Nile et al (2022)). As well, it showed an almost significant effect on the uptake of the P and K nutrients along with the Na/K ratio in the seeds and/or the straw (Tables 6 and 7).…”

Green synthesis trends and potential applications of bimetallic nanoparticles towards the sustainable development goals 2030

“… 60 These reactions are favorable since plant leaves comprise several functional groups and phytochemicals acting as stabilizing and reducing agents. 61 Polyethylene glycol 62 and starch 63 are some of the commonly used materials to achieve a biomolecule-mediated synthesis of metallic NPs. Lastly, waste material-mediated synthesis is one of the less explored types of synthesis.…”

“…Compared to traditional (also known as “physicochemical”) methods, a remarkable advantage is that green synthesis involves fewer reactants, since, in most cases, reducing and stabilizing agents are the same substance. 61 Furthermore, green nanotechnology presents the advantage of energy efficiency and cost-effectiveness as the synthesis carried out following its principles is low in energy consumption and, consequently, low cost. In addition, they are clean and easy and show a decrease in the production of greenhouse gasses and wastes, as well as a minimal consumption of non-renewable raw materials.…”

Climate Smart Agriculture: The Role of Fertilizer Innovations and Efficient Plant Nutrient Management

“…Smart delivery systems which use nanotechnology, have some positive impacts on climate-smart agriculture. These systems encompass advantages in a broad range such as self-regulating ability, the ability to regulate remotely, target-based action, and most importantly having multifunctional characteristics to resist climate stress (Yadav et al, 2023).…”
