Strategies for N Based Nanofertilizers Use in Grasslands. Because grassland ecosystems present unique features compared to traditional annual or perennial crops, the approach for applying nanofertilizers should follow a particular strategy (), considering grass harvest by cattle and the different grazing patterns during the year, …

Use of non-conventional and economically sound chitosan-based technology (nano-fertilizers) is thought to play pivotal role in upscaling the future agriculture and to combat the global food crisis (Fig 1) (Feregrino-Perez et al., 2018).The promising nanotechnology is thought to enhance crop production, minimize overuse of synthetic …

The effects of NFs may be regulated by characteristics of soil, environment, delivery mechanism of NPs, and plant species. The foliar method of entry has proven to be the most effective, as nutrients may be easily absorbed through nanosized pores found in leaf plasmodesmata (Iqbal, 2019; Rajput et al., 2021; Kalwani et al., 2022).

Nanofertilizers can be produced by adding nutrients individually or in combination to the adsorbents with nano-dimensions. In the case of cationic nutrients, …

The use of NFs was found to be one of the most effective methods for increasing resource efficiency, plant production, and lowering ... Shahraki, A.D. Nanofertilizers and their roles in sustainable …

Excessive use of synthetic fertilizers cause economic burdens, increasing soil, water and atmospheric pollution. Nano-fertilizers have shown great potential for their …

Nanofertilizers improves the surface area available for various metabolic reactions in the plant system, resulting in a faster rate of photosynthesis and higher crop dry matter and yield.

A nanohybrid construct like nanofertilizers (NFs) is an excellent alternative to overcome the negative impact of traditional chemical fertilizers. The NFs provide smart nutrient delivery to the plants and proves their efficacy in terms of crop productivity and environmental sustainability over bulky chemical fertilizers. ... Physical methods ...

Nanofertilizers. Nanofertilizers are plant nutrients wholly or partially composed or engineered of nanostructured formulation(s) that can release active ingredients into the soil slowly and in a controlled manner, thereby preventing nutrient loss, eutrophication, and the pollution of water and air.

These characteristics of nanofertilizers make them exceedingly suitable for their use in modern agriculture [19,51]. ... Various methods for the delivery of nanofertilizers to plants are listed below. 3.4.1. In Vitro Methods. Aeroponics and hydroponics are both soil-less (without soil) methods. In aeroponics, the plant's roots …

nanofertilizer is essential to Þnd the best application method. Nanofertilizers can be ap-plied to plants through foliar, water, and soil application [6]. Figure 3. ClassiÞcation of nanofertilizers.

Soil microbial biomass carbon in soil samples was estimated as per the method of Ref. 29. ... (2018). They concluded that after the application of Zinc oxide (ZnO) nanofertilizers (0.5–2 mg/g), ...

Nanofertilizers can be synthesized either by top-down (physical method) or bottom-up approach (chemical method). The top-down approach is based on the reduction of size to ... In addition to the chemical and physical methods, nanofertilizers can also be synthesized by using biological method (biosynthesis) which is called green synthesis.

noticed when treated with biogenic Cu nanofertilizers having 20 nm size. Molybdenum Nanofertilizers: Molybdenum is required in very small quantities. The range is between 0.3 and 1.5 ppm for most of plant tissue and between 0.01 and 0.20 ppm for a growing medium. Mo nanofertilizers solution as a micronutrient source of Mo for chickpea

Here, the granules are allowed to flow in a fabricated orbit under the influence of an air stream, which is considered an efficient method for the prepared controlled release of nanofertilizers. For instance, polyacrylic acid (PAA) acts as an appropriate material for coating urea [ 27 ] as it acts as a barrier to prevent nitrogen loss.

The latter properties allow nanostructured fertilizers to be used as an intelligent delivery system for plant nutrients. Nanofertilizers are released very slowly compared to conventional fertilizers. Nanofertilizers are projected as a tool to meet the criteria for sustainably intensifying agricultural practices over the next 30 years.

Different kinds of encapsulation methods incclude: (a) encapsula-tion of nutrients with nanomaterials like nanotubes or nanoporous materials, (b) coating of nutrients with a thin protective layer of polymer and (c) formulations which can deliver nutrients as par-ticles or emulsions of nanoscale dimensions [9,10]. Need for nanofertilizers

Nanofertilizers have the potential for targeted administration and regulated release since they are more soluble, reactive, and penetrable through the cuticle. Nanofertilizers reduce the toxicity of heavy metals, stress caused by abiotic factors, boosts crop development, production, quality, and the efficiency with which nutrients are utilized.
