Abstract: The utilization of Nano-hydroxyapatite (nHAP) in agriculture has garnered significant attention in recent years due to its unique properties and potential benefits for enhancing crop growth and soil fertility. This review explores the diverse applications of Nano-hydroxyapatite in agricultural practices and highlights its multifaceted utility. Nano-hydroxyapatite, a nanoscale form of calcium phosphate, exhibits excellent biocompatibility and bioactivity, making it an attractive candidate for agricultural purposes. One key area of focus is its role in soil amendment and nutrient management. Nano-hydroxyapatite can serve as a slow-release fertilizer, gradually supplying essential nutrients such as calcium and phosphorus to plants. Its nanoscale structure enhances nutrient uptake efficiency, promoting healthier plant growth and improved crop yields. Furthermore, nano-hydroxyapatite demonstrates the ability to enhance soil structure and water retention, contributing to better soil quality and reduced water requirements for crops. Its interaction with soil microorganisms also influences microbial activity, potentially benefiting nutrient cycling and overall soil health. Beyond its direct impact on plants and soil, nano-hydroxyapatite has been investigated for its potential in crop protection. Studies suggest its role in the development of nanopesticides, providing a targeted and controlled release of pest management agents. Despite the promising applications, challenges and potential environmental impacts of nano-hydroxyapatite in agriculture warrant further research and careful consideration. This review provides a comprehensive overview of current research findings, discussing the potential advantages and challenges associated with the integration of nanohydroxyapatite in agricultural practices. As the agricultural sector seeks sustainable and innovative solutions, the exploration of nanohydroxyapatite opens avenues for improved resource efficiency and enhanced crop productivity.
