Nanotechnology aids in the field of agricultural sciences in reducing environmental pollution by using nanoparticles and nanocapsules that have the capacity to control or delay delivery, absorption, and are more efficient and environmentally friendly. In addition, nanocrystals are produced to improve the efficacy of pesticides so that they can be applied in lower doses. Since fertilizers are the primary cause of worry and use nanotechnology to provide more efficient solutions, creating fertilizer using nanotechnology would be a novel development in this field. Using modern nanotechnologies, there are still many opportunities for agricultural research.
