Nanotechnology implies the scientific research, development, and manufacture, along with processing, of materials and structures on a nano scale. Presently, the contamination of metalloids and metals in the soil has gained substantial attention. The consolidation of nanomaterials and plants in ecological management has received considerable research attention because certain nanomaterials could enhance plant seed germination and entire plant growth. Conversely, when the nanomaterial concentration is not properly controlled, toxicity will definitely develop. This paper discusses the role of nanomaterials as: (1) nano-pesticides (for improving the plant resistance against the biotic stress); and (2) nano-fertilizers (for promoting the plant growth by providing vital nutrients). This review analyzes the potential usages of nanomaterials in agroecosystem. In addition, the adverse effects of nanomaterials on soil organisms are discussed. We mostly examine the beneficial effects of nanomaterials such as nano-zerovalent iron, iron oxide, titanium dioxide, nano-hydroxyapatite, carbon nanotubes, and silver- and copper-based nanomaterials. Some nanomaterials can affect the growth, survival, and reproduction of soil organisms. A change from testing/using nanomaterials in plants for developing nanomaterials depending on agricultural requirements would be an important phase in the utilization of nanomaterials in sustainable agriculture. Conversely, the transport as well as ecological toxicity of nanomaterials should be seriously examined for guaranteeing its benign usage in agriculture.

“…However, nZVI tends to aggregate rapidly due to its magnetic property and small size, which greatly inhibits its reactivity (Xue et al, 2018b). To resolve this problem, synthesized nZVI particles have been usually supported on different surface-modified materials to enhance its removal ability on heavy metals (Cai et al, 2019). Zeolite, sepiolite, RM, and biochar (BC) are low-cost mineral and carbon-based materials that have been used to remove heavy metal pollution with high efficiencies (Mahar et al, 2015).…”

“…However, any technology can be a double edge sword though potential environmental risk should be neglected due to wide application nanomaterials. Once conveyed into soil their separation is not easily separation after soil restoration which can cause secondary pollution [7]. To eliminate the threat of nanocomposite and continuous development are needed to improve the implication and separation mechanism preventions.…”

“…Magnetic nanomaterials have several advantages over other materials such as smooth operation, high efficiency, reusability of adsorbent and above all economically favorable for in-situ remedies [6]. Cai et al, also highlighted that nanomaterials can be used for nanotechnology development of in-situ remediation [7]. However, other material can changed the reclaimed properties of reclaimed soil [8].…”

Soil contamination by with heavy metal(loid)s (HMs) has been a major environmental challenge for decades and escalating with industrialization development which is considered as a hindrance of socioeconomic development. Nevertheless, cost and time-effective, and sustainable in-situ remediation technologies remain facing technical and operational lacking. Magnetic nanomaterials have shown promising means of an innovative in-situ remediation strategy for the removal of PTMs contaminated soil. Magnetic adsorbent having high efficiency and capacity towards the removal of PTMs, and enormous reusability. Also, magnetic nanocomposite has improved with functionalization of groups on their large surface which increase the adsorption capability of the adsorbent. Nanotechnology development sector or enterprises as lack of field application of magnetic nanomaterials at commercial scale due to non-availability of required tools and materials. This information may support further environmental nanotechnology for contaminated soil.
