Integrative approaches to optimize phosphorus utilization and ecological balance in farmland systems

Phosphorus is a critical, non-renewable nutrient that underpins global food production and ecosystem health. Despite its importance, phosphorus use efficiency (PUE) in farmland remains alarmingly low, with only 15–25% of applied phosphorus absorbed by crops. The remainder is often immobilized in soil or lost through runoff, contributing to resource depletion and eutrophication of aquatic systems. Recent advances in plant physiology, molecular biology, and soil science have illuminated complex mechanisms of phosphorus uptake, translocation, and recycling in plants. However, significant knowledge gaps persist in understanding how these processes can be harnessed and regulated to achieve sustainable nutrient management. The global transition toward ecological agriculture and the implementation of the Sustainable Development Goals (SDGs) further emphasize the need for an integrative framework to enhance P efficiency, minimize environmental risks, and support circular nutrient economies.This Research Topic aims to integrate cutting-edge insights across disciplines to improve phosphorus management and utilization in farmland systems. The goal is to deepen theoretical and practical understanding of plant phosphorus physiology, elucidate molecular and regulatory mechanisms governing P efficiency, and develop innovative technologies that optimize fertilizer use while mitigating ecological impacts. It also seeks to explore adaptive strategies that enable crops to maintain productivity under low-phosphorus conditions and to encourage the development of sustainable nutrient recycling systems. By synthesizing advances in plant–soil–microbe interactions and precision agriculture, the initiative aspires to provide a scientific foundation for reducing dependency on non-renewable P resources and promoting sustainable farmland ecosystems aligned with the SDGs.To gather further insights into efficient phosphorus management in farmland and ecological agriculture, we welcome contributions focused on interdisciplinary and sustainable solutions. Articles should emphasize integrative approaches that combine theory with applicable technologies. We invite submissions addressing, but not limited to, the following themes:o Crop phosphorus physiological utilization and adaptive responses to low-P conditionso Molecular and physiological regulatory mechanisms influencing P efficiency, including gene function and signaling pathwayso Plant–microbe and rhizosphere interactions enhancing P acquisition and recyclingo Development and application of innovative P fertilizers, such as slow- or controlled-release formulations and precision fertilization techniqueso Phosphorus balance assessment, loss mitigation, and ecological risk control in farmland systemso Recycling strategies for phosphorus recovery from organic and waste sourceso Integration of phosphorus management into ecological agriculture and circular economy frameworksWe welcome original research articles, review papers, and short communications presenting novel findings, innovative methodologies, or comprehensive syntheses that advance phosphorus use efficiency and sustainable agricultural practices.
