Nanofertilizers: Types, Delivery and Advantages in Agricultural Sustainability

In an alarming tale of agricultural excess, the relentless overuse of chemical fertilizers in modern farming methods have wreaked havoc on the once-fertile soil, mercilessly depleting its vital nutrients while inflicting irreparable harm on the delicate balance of the surrounding ecosystem. The excessive use of such fertilizers leaves residue on agricultural products, pollutes the environment, upsets agrarian ecosystems, and lowers soil quality. Furthermore, a significant proportion of the nutrient content, including nitrogen, phosphorus, and potassium, is lost from the soil (50–70%) before being utilized. Nanofertilizers, on the other hand, use nanoparticles to control the release of nutrients, making them more efficient and cost-effective than traditional fertilizers. Nanofertilizers comprise one or more plant nutrients within nanoparticles where at least 50% of the particles are smaller than 100 nanometers. Carbon nanotubes, graphene, and quantum dots are some examples of the types of nanomaterials used in the production of nanofertilizers. Nanofertilizers are a new generation of fertilizers that utilize advanced nanotechnology to provide an efficient and sustainable method of fertilizing crops. They are designed to deliver plant nutrients in a controlled manner, ensuring that the nutrients are gradually released over an extended period, thus providing a steady supply of essential elements to the plants. The controlled-release system is more efficient than traditional fertilizers, as it reduces the need for frequent application and the amount of fertilizer. These nanomaterials have a high surface area-to-volume ratio, making them ideal for holding and releasing nutrients. Naturally occurring nanoparticles are found in various sources, including volcanic ash, ocean, and biological matter such as viruses and dust. However, regarding large-scale production, relying solely on naturally occurring nanoparticles may not be sufficient or practical. In agriculture, nanotechnology has been primarily used to increase crop production while minimizing losses and activating plant defense mechanisms against pests, insects, and other environmental challenges. Furthermore, nanofertilizers can reduce runoff and nutrient leaching into the environment, improving environmental sustainability. They can also improve fertilizer use efficiency, leading to higher crop yields and reducing the overall cost of fertilizer application. Nanofertilizers are especially beneficial in areas where traditional fertilizers are inefficient or ineffective. Nanofertilizers can provide a more efficient and cost-effective way to fertilize crops while reducing the environmental impact of fertilizer application. They are the product of promising new technology that can help to meet the increasing demand for food and improve agricultural sustainability. Currently, nanofertilizers face limitations, including higher costs of production and potential environmental and safety concerns due to the use of nanomaterials, while further research is needed to fully understand their long-term effects on soil health, crop growth, and the environment.

“…At the same time, the introduction route of the TiO 2 -NMs to the plant system plays an essential role in the toxicological mechanisms that may arise due to the variety of tissues or organs with which they can interact (roots, leaves, stem, etc.) (R. Singh et al, 2021).…”

“…Based on previous reports, the interaction between plant/TiO 2 -NM can positively or negatively affect the plant product's quality, such as a higher or lower production rate, depending on the plant species (R. Singh et al, 2021). However, one area with potential applications is the stress induction by TiO 2 -NMs.…”

The present study analyzed Medicago sativa L. crops irrigated by TiO2 in the anatase phase and TiO2 doped with Ag, Fe, Cu ions at 0.1%w synthesized by the sol-gel method (SG) and the sol-gel coupled with microwaves (Mw-SG). The materials were added to the irrigation water at different concentrations (50, 100, and 500 ppm). Affectation levels were observed by measuring stem morphology, chlorophyll content, secondary metabolite content (total phenolic, flavonoids), and antioxidant activity by 2,2-diphenyl-1-picrylhydrazyl radical assay. The results revealed a reduction in stem and leave size at different concentrations and chlorophyll content, showing no correspondence with the applied dose. Nanostructured materials in the soil generated nitrogen, boron, and potassium deficiencies observed in leaves. No linear effect related to the increase in total gallic acid, rutin content, and antioxidant activity dependent on concentration was determined. The stress factor depended on the dopant type, generating different stress levels at the three organs investigated (leaves, roots, stem). The metabolite augmentation was mainly obtained at 100 and 500 ppm for both synthesis methods.
