Nanofertilizers (NF), an advancing aspect of agricultural technology, have generated significant attention to augment nutrient dynamics in crops. This chapter examines the influence of NF on soil physicochemical characteristics, with a particular focus on their ability to release nutrients, modify soil structure, and regulate pH levels. The purpose of these innovative fertilizers is to gradually release nutrients; hence enhance the absorption by plants and increase agricultural output. The interplay between NFs and soil particles impacts soil aggregation, texture, and water retention. Furthermore, the possible impacts on soil pH, microbial populations, and the breakdown of organic matter are examined, highlighting the complex relationship between nanomaterials and the soil ecosystem. Although NFs have the potential for sustainable agriculture, it is essential to carryout comprehensive research to understand their long-term consequences, including residual effects and environmental implications. This chapter emphasizes the need of exercising prudence in the implementation, conducting thorough environmental surveillance, and establishing regulatory frameworks to assure the appropriate usages. Continuous study is crucial for obtaining a thorough comprehension of the effects of NF on soil health. This knowledge serves as a basis for making educated decisions on agricultural methods and ensuring sustainable food production.
