Enhancing biodiversity could improve P-use efficiency of grasslands,  which is beneficial given that rock-derived P fertilisers are expected  to become scarce in the future. Here, we show in a biodiversity  experiment that more diverse plant communities were able to exploit P  resources more completely than less diverse ones. In the agricultural  grasslands that we studied, management effects either overruled or  modified the driving role of plant diversity observed in the  biodiversity experiment. Nevertheless, we show that greater above-  (plants) and belowground (mycorrhizal fungi) biodiversity contributed to  tightening the P cycle in agricultural grasslands, as reduced  management intensity and the associated increased biodiversity fostered  the exploitation of P resources. Our results demonstrate that promoting a  high above- and belowground biodiversity has ecological (biodiversity  protection) and economical (fertiliser savings) benefits. Such win-win  situations for farmers and biodiversity are crucial to convince farmers  of the benefits of biodiversity and thus counteract global biodiversity  loss. <\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img src=\"\/wp-content\/uploads\/image-168-1024x548.png\" alt=\"\" class=\"wp-image-3481\"\/><figcaption>Panel\u00a0(<strong>A<\/strong>) refers to the biodiversity experiment and Panel\u00a0(<strong>B<\/strong>)  shows the\u00a0agricultural grasslands.
