A revolutionary approach to promoting sustainable agriculture is the use of biodegradable nanoparticles to enhance crop productivity and reduce environmental impacts. Biodegradable nanoparticles improve the bioavailability and controlled release of agricultural inputs, minimizing waste and runoff while reducing the chemical usage. Their biodegradability ensures minimal residue accumulation and fostering ecological balance. The utilization of chemical and biological agricultural inputs is fundamental to every economy. The application of chemical fertilizers and pesticides causes unanticipated consequences like negative impact on the ecosystem and ecological equilibrium. Biofertilizers and biopesticides mitigate some adverse environmental impacts of chemical agricultural inputs. Modern developments in nanotechnology present the potential for sustainable agriculture, which entails resolving issues related to both agriculture and the environment. Nanomaterials utilized in agriculture, especially nanofertilizers and nanopesticides, provide a gradual and prolonged release in addition to environmentally beneficial characteristics. NPs can be customized to meet the exact requirements of the plants. Nanofertilizers have enhanced stress tolerance, rendering them very valuable in the context of climate change. Moreover, nanopesticides and nanofertilizers have very less requirements which cause transportation expense reduction and a positive impact on the economy.
