Plant growth, productivity, and quality are all impacted by environmental factors such as abiotic stress and limited soil nutrients. Low phosphorus availability is a prevalent soil-related abiotic stress in both natural and agricultural ecosystems. Most mineral elements are absorbed by the action of nutrient-absorption proteins in plants. The absorption of nitrate ions by the root is regulated by high-affinity transport system. Soil may be supplemented with organic matter from several sources. The biochar is thought to have the potential to be a long-term carbon sink capacity. Carbon sequestration is an essential component of regenerative agriculture that helps to slow down global warming. Under these demanding circumstances, NPs can aid in protecting the photosynthetic machinery and enhancing photosynthesis. Certain nanoparticles, such cerium oxide and TiO2 nanoparticles, shield the photosynthetic apparatus from oxidative damage. Prolonged dryness has also been shown to impair root development, stomatal opening, leaf size, leaf water potential, and seed quantity, size, and tolerance, which prevents flowering and fruiting and lowers crop yield. By altering the availability and plant absorption of fertilizer nutrients in the soil, engineered nanomaterials can increase crop production. By directly acting on phytopathogens through the formation of reactive oxygen species, these can limit crop illnesses.
