Soil pollution, characterized by the presence of harmful chemicals or substances in concentrations that adversely affect non-target organisms, is a growing environmental concern. The projected global population increase of 2 billion over the next 30 years has intensified the demand for agricultural productivity, leading to widespread soil degradation. Toxic metals, hydrocarbons, agrochemicals, and excess nutrients from industrial, agricultural, and urban activities contribute significantly to this issue. This creates a pressing conflict between the pursuit of immediate economic benefits and the need for sustainable soil management, emphasizing the urgency of adopting innovative remediation strategies. To combat soil pollution, emerging strategies such as phytoremediation, nanoremediation, biochar application, and electrokinetic remediation offer promising solutions. These approaches, whether applied individually or as part of integrated systems, address the limitations of traditional methods and aim to restore soil quality. Phytostabilization using endophytic bacterial strains by many studies has been reported to reduce heavy metal toxicity in soil while enhancing plant growth. Likewise, bioremediation techniques, including bioaugmentation (BA) and biostimulation (BS), have demonstrated significant efficacy in degrading petroleum hydrocarbons. These methods resulted enhanced germination of seeds and also increase microbial activity in contaminated soils. Nanotechnology also has emerged as a powerful tool for soil remediation where different magnetic nanoparticle systems can be effectively used to degrade hydrocarbons more efficiently than conventional methods. Similarly, biochar applications electrokinetic remediation, coupled with permeable reactive barriers, further aids in reducing pollutants and heavy metals. Thus, leveraging these advanced methodologies, along with interdisciplinary research and community involvement, offers scalable and adaptable solutions to diverse and evolving environmental challenges. By such innovative approaches, sustainable soil resource management can be achieved, ensuring the long-term health and productivity of vital ecosystems while balancing ecological preservation with economic growth.
