Plant–Soil Synergy Through Organic Amendments: Unlocking Abiotic Stress Resilience

Improving plant and soil health is essential for building climate-resilient agricultural systems capable of sustaining global food production. Modern cropping environments face increasing pressures from salinity, drought, heat, nutrient depletion, and soil degradation stressors that weaken plant performance and limit yield potential. Organic and carbon-rich amendments such as composts, biochar, plant residues, seaweed-based formulations, and microbial inputs offer effective, nature-based solutions to restore soil function and strengthen plant resilience.These amendments improve soil structure, water-holding capacity, and nutrient availability while stimulating microbial activity and promoting carbon stabilization. Enhanced soil quality directly influences plant nutrient uptake, root development, and overall physiological stability under adverse conditions. Organic amendments have also been shown to support antioxidant activity, osmotic balance, and stress adaptation pathways, contributing to improved plant growth and yield under challenging environments.A deeper understanding of these benefits depends on advanced analytical tools that capture soil-plant interactions at multiple scales. Emerging technologies including high-throughput sequencing, metabolomics, soil microbiome profiling, soil EC sensors, digital fertigation systems, remote sensing, and predictive modeling offer new opportunities to map how soil amendments influence nutrient cycling, carbon turnover, microbial networks, and plant performance. Integrating these approaches is essential for identifying the mechanisms by which organic amendments improve soil health and enhance plant tolerance to abiotic stress.Despite growing global interest, substantial gaps remain in linking soil quality improvements to measurable physiological, biochemical, and agronomic outcomes in plants. This Research Topic seeks to address these gaps by bringing together interdisciplinary research that connects soil amendment strategies, soil carbon dynamics, stress physiology, yield enhancement, and advanced analytical methods. By uniting field experiments, controlled trials, multi-omics platforms, imaging tools, and predictive modeling, this collection will support the development of sustainable, nutrient-efficient, and climate-resilient agricultural systems.Key Themes (but not limited to):• Nutrient transport, signaling, and abiotic stress adaptation in plants• Nutrient enrichment and nutrient-use efficiency resulting from organic inputs• Plant physiological and biochemical responses to abiotic stress in improved soils• Soil amendments and their role in improving soil quality and fertility• Advanced plant–soil interaction analysis using multi-omics and sequencing technologies• Processes of soil carbon cycling and carbon stabilization in amended soils• Use of soil sensors, imaging tools, and precision technologies for nutrient and water monitoring• Soil improvement strategies contributing to enhanced plant growth, yield, and quality• Nature-based amendment approaches for climate-resilient and sustainable agriculture Topic editors: Dr Rathinapriya Periyasamy, Seung Tak Jeong, MJV Largia, Dr Maharajan Theivanayagam Source: https://www.frontiersin.org/research-topics/76476/plant-soil-synergy-through-organic-amendments-unlocking-abiotic-stress-resilience
