Öğe Soil fertility in arid lands: strategies for sustainable management and fertilization(Elsevier, 2025) Hikmet Gunal; Mesut Budak; Elif Gunal; Miraç Kilic; Abdel Rahman Mohammad Al Tawaha; Abdel Razzaq Al-Tawaha; Arun Karnwal; Nataliia Nesterova; Abhishek Singh; Vishnu D. Rajput; Karen Ghazaryan; Tatiana Minkina; Iftikhar Ali; Amjad M. Husaini; Tauseef A. Bhat; Rahul Kanaoujiya; Rizwan RashidArid and semiarid regions, constituting approximately 30% of the Earth’s land surface and home to over 2 billion people, face pressing challenges in maintaining soil fertility and agricultural productivity amid intensifying agriculture, climate change, and limited resources. This chapter explores the complex dynamics of assessing soil fertility in these regions, emphasizing the need for innovative assessment approaches that integrate traditional knowledge, advanced technologies, and data-driven insights. The multifaceted nature of soil fertility, encompassing organic, mineral, physical, and biological aspects, requires a balanced and optimized approach for sustainable agricultural production. Soil fertility decline, though less visible than erosion, poses a significant threat to agricultural productivity and food security. Investigating and mitigating soil fertility loss demand attention, emphasizing the importance of long-term research and monitoring to comprehend slow and seasonal changes in soil properties. Farmers, equipped with valuable knowledge gained through years of observation, play a pivotal role in shaping effective agricultural programs and policies. Integrating farmers’ perceptions into decision-making processes enhances the sustainability and effectiveness of interventions. Oil analysis, especially in regions with low fertility, high pH, and low organic matter, empowers farmers to make informed decisions regarding crop selection, irrigation, and fertilization practices. Innovative tools, including portable spectrophotometers, hyperspectral imaging, and artificial intelligence (AI), offer promising solutions to overcome limitations in conventional nutrient analysis method and to optimize resource allocation and enhancing productivity. Static soil maps are relics of the past. Digital soil mapping (DSM), leveraging environmental data and advanced algorithms, offers a dynamic and highly accurate picture of soil fertility variations, enabling targeted interventions and informed land-use planning. Recommendations for promoting farmer-centric approaches, investing in research and technology adoption, embracing DSM and AI, nurturing traditional knowledge, and prioritizing resource conservation are outlined. Investing in research, technology adoption, and farmer-centric approaches is crucial. We must embrace traditional knowledge, promote DSM and AI, and prioritize resource conservation. By implementing these recommendations, resilient soils in arid and semiarid regions can be cultivated, ensuring long-term health and productivity crucial for global food security. Collaboration between scientists, policymakers, and farmers is essential for the success of these strategies, offering a path toward sustainable agriculture in challenging environments.
