Soil and water resources are under mounting pressure from climate variability, land degradation, and the intensification of agricultural production. In many regions, inappropriate or excessive nutrient applications undermine crop productivity in the long term, while simultaneously accelerating soil erosion, depleting soil organic carbon stocks, and contaminating surface and groundwater bodies. These interconnected processes not only compromise ecosystem integrity but also pose significant risks to food security, rural livelihoods, and environmental sustainability.
Yet, nutrient management also represents a powerful entry point for change. When carefully designed and context-specific, nutrient strategies can enhance soil fertility, stabilize agricultural landscapes, and reduce diffuse pollution. Advances such as precision fertilization, the recycling of organic amendments, integrated crop–soil–water systems, and the use of digital decision-support tools are opening new pathways to improve nutrient efficiency. These innovations have the potential to transform agriculture into a driver of soil conservation, water protection, and climate resilience, ensuring that productivity gains are achieved without sacrificing ecological health.
We particularly welcome contributions on (but not limited to):
• Precision nutrient application and decision-support tools to minimize losses
• Conservation agriculture practices (e.g., cover crops, crop rotations, no-till) and their impact on soil fertility and hydrological cycles
• Interactions between nutrient management, soil organic carbon dynamics, and erosion control
• Monitoring and modelling of nutrient fluxes in soil–water systems at plot, farm, and watershed scales
• Nature-based and agroecological solutions, and Biostimulants for nutrient retention and water conservation
• Policy, socio-economic, and farmer-engagement perspectives on sustainable nutrient management
By bringing together soil scientists, agronomists, hydrologists, ecologists, and modelers, this session seeks to foster interdisciplinary dialogue and promote actionable solutions for sustainable land and water management. Contributions from early-career scientists, as well as examples from Mediterranean, arid, and semi-arid regions, are especially encouraged.
