Phosphorus: a limiting nutrient for humanity?   总被引:2,自引:0,他引:2  
Highlights? P is essential to build key molecules, such as RNA needed for rapid growth. ? P is often limiting to productivity in ecosystems, including to crops. ? Large amounts of P are mined annually to make fertilizer to produce food. ? Current P use is unsustainable owing to ecosystem impacts and uncertainties about fertilizer production. ? A food system redesign to combine P-efficient crops with P recycling is needed.  相似文献
