Global agriculture is severely hampered by soil salinity, jeopardizing environmental sustainability and food security. An excessive buildup of soluble salts in the soil hinders plant development and production by interfering with water intake, changing nutrient availability, and causing ion toxicity. This phenomenon is especially common in arid and semi-arid areas, where poor drainage and inappropriate irrigation techniques worsen salt problems. To deal with osmotic stress, ion imbalance, and oxidative damage, plants exposed to saline environments trigger intricate physiological and biochemical processes at the cellular level. These reactions include the production of proline and other osmoprotectants, the overexpression of antioxidant enzymes to lessen oxidative stress, and activating ion transporters to preserve ionic equilibrium. Despite these adaptive responses, long-term salt frequently overwhelms plant defenses, resulting in restricted development and yield reductions. A multifaceted strategy incorporating cutting-edge technologies and sustainable farming methods is needed to address soil salinity. Techniques including using halophyte-based farming systems, adopting soil supplements, increasing irrigation efficiency, and using salt-tolerant crop types have demonstrated promise in reducing the consequences of salinity. Additionally, using salt-tolerant microorganisms for bioremediation and sophisticated remote sensing methods for salinity monitoring might improve the accuracy of saline landscape management. A thorough grasp of salinity dynamics and using scalable, sustainable remedies will be essential to preserving ecological health and agricultural output as climate change worsens.
