The scientific study, creation, and alterations of materials and structures at the nanoscale is often referred to as “nanotechnology.” The agricultural and industrial sectors have recently paid close attention to soil contamination by metals and metalloids. Certain nanomaterials may enhance the germination of plant seeds and the general growth and development of plants. Scientific interest in integrating nanomaterials inside plants for ecological administration is high. However, if the concentration of the nanomaterial is not adequately controlled in industrial and agricultural sectors, toxicity will likely result. Copper-based nanomaterials have demonstrated significant potential in soil and environmental remediation applications, including CO2 reduction, wastewater treatment, and biosensing. Copper-based nanomaterials have demonstrated significant potential in soil and environmental remediation applications, including CO2 reduction, wastewater treatment, and biosensing. Because of their non-toxicity, low allergenicity, and biodegradability, copper-based nanomaterials are an efficient and sustainable method of safeguarding crops or soil during soil restoration. Scientists and researchers have demonstrated that copper-based nanoparticles may be utilized for soil remediation and to clean up various polluted surroundings, which will ultimately result in a safer and better world for everyone involved in agriculture. This chapter summarizes the information showing, in terms of soil protection, using copper-based nanomaterials and their special agro nano-chemicals in soil remediation is not only safer for soil in the agricultural sector but also more affordable and kinder to the environment.
