Food chain has been altered through farming nanotechnology, which energizes such elements as Sulfur (S) and Selenium (Se), and several industries, such as crop farming, aquaculture, tree forestry, animal and poultry farms, and plant nutrients, have utilized this technology. Sulphur nanofertilizers reduce the stress level on the environment, increase the fertility of the soil, and optimize nutrient release. Selenium agents impede the occurrence of micronutrient insufficiency in human beings and animals, and Chalcogenide concentration minimizes the intake of synthetic additives and optimizes the conversion rate of feeds. The use of sulfur fertilizer helps activate sprouting and improves tolerance to diseases. Intelligent sensors with chalcogenides and optoelectronic agricultural plans can provide real-time information on the moisture of the soil, soil nutrients, and stress. These products increase nutrition, demand fewer resources, and provide adaptable agriculture approaches in an evolving climate.
