+Technological Advancement in the Development of Nano Fertilizers for Sustainable Agriculture

This review explores the significance of nano fertilizers in addressing the concerns associated with the indiscriminate application of chemical fertilizers in agricultural soil. It focuses on the need for crop and soil-specific fertilizer application to prevent nitrogen overuse and proposes nanomaterials as a viable solution for amending soil with plant nutrients. The review examines the potential of nanomaterials for soil nutrient enhancement and discusses the different techniques involved in synthesizing nanofertilizers. It emphasizes the importance of studying both macronutrients and micronutrients concerning plants and explores the effectiveness of applying nanoparticles through roots or leaf surfaces regarding plant absorption rates. The review highlights that nano fertilizers have effectively raised crop yields by providing the ideal and necessary nutrients. It discusses how nano fertilizers can alleviate the heavy burden of chemical fertilizers, reduce associated costs, and promote sustainable agriculture. In conclusion, the review suggests that nano fertilizers offer a promising alternative to traditional chemical fertilizers. Farmers can mitigate the negative impacts of excessive nitrogen use while boosting crop yields by applying nano fertilizers in a targeted and soil-specific manner. The findings indicate that nano fertilizers, created through various synthesis techniques, can contribute to sustainable agriculture by providing adequate plant nutrients and reducing the reliance on chemical fertilizers.
