Global agriculture is at a critical situation, which is challenged by soil degradation, climate variability, declining nutrient use efficiency and growing food demands. The conventional input-intensive farming has often undermined long-term soil health and ecosystem services. In response, agro-ecological approaches are gaining momentum as a science based, socially inclusive, and environmentally sustainable alternative. These novel approaches emphasize biodiversity, ecological balance and the integration of traditional knowledge with modern innovations. Simultaneously, the smart nutrient management powered by digital tools, AI models, and site-specific data offers the potential to optimize fertilizer use, reduce losses, and enhance crop productivity. The convergence of agroecology and digital nutrient solutions presents a unique opportunity to transform food and land use systems into more resilient, adaptive and sustainable models. This Research Topic invites interdisciplinary efforts to explore these synergies for future ready agriculture.

Modern agriculture is increasingly confronted with the dual challenge of maintaining high productivity while safeguarding environmental and soil health. Excessive reliance on synthetic fertilizers has led to nutrient imbalances, groundwater contamination, greenhouse gas emissions, and declining soil fertility. At the same time, climate change continues to exacerbate land degradation and disrupt food production systems. To address these challenges, there is an urgent need to transition from linear, input heavy nutrient practices to circular, adaptive and knowledge-intensive systems. This Research Topic aims to explore the integration of agro-ecological principles with smart nutrient management tools to enhance land use resilience and food system sustainability. Recent advances in remote sensing, AI-powered diagnostics, precision agriculture, and digital soil mapping have opened new frontiers for site-specific, resource-efficient nutrient management. When combined with agroecological strategies such as intercropping, composting, and legume-based rotations, these innovations can regenerate soils, optimize yields and improve nutrient use efficiency. This collection seeks contributions that bridge ecological science, digital technology, and practical applications to redesign resilient agroecosystems.

This Research Topic invites original research, reviews, case studies, and perspective articles that address the intersection of agro-ecological practices and smart nutrient management to build resilient land use and food systems. The editors encourage interdisciplinary contributions that explore innovative approaches integrating ecological principles with digital, data-driven, AI-enabled nutrient management tools etc.
