Phosphate is one of the most important limiting nutrients for crop growth and production. Plant acquisition of soil phosphate largely depends on root proliferation to accelerate soil exploration, and on phosphate bioavailability mediated by root exudates and rhizosphere microorganisms. Central to this is the need for a better understanding of the complex biogeochemical interfaces in the rhizosphere. This project explores recently developed non-destructive imaging, isotope, and metabolism techniques to generate a systematic research tool in tracking rhizosphere interactions and imaging phosphate dynamics from macroscale to nanoscale levels. This study will provide new opportunities to improve crop nutrient use efficiency and crop production.

磷是作物生长和生产的重要限制性营养元素之一。植物对土壤磷的吸收主要依赖于根系的增殖和根系分泌物及根际微生物对磷的生物有效性。这一点的核心是需要更好地了解根际复杂的生物地球化学界面。该项目探讨了最近开发的非破坏性成像，同位素和代谢技术，以产生一个系统的研究工具，跟踪根际相互作用和成像磷酸盐动态从宏观到纳米级水平。该研究将为提高作物养分利用效率和作物产量提供新的机遇。
