How do legumes improve phosphorus uptake of the following wheat?

&lt；p&gt； 只有大约20%的磷肥被小麦等作物吸收，其余的以固定的形式积累在土壤中。利用这种固定的土壤磷库可能会减少化肥的使用。一些豆科作物可以利用部分土壤磷库，促进后茬小麦的生长和磷吸收。然而，这种生长和磷吸收改善背后的机制尚不清楚。在这项多学科的国际合作中，我们将阐明豆类-小麦轮作中磷库和土壤微生物群落组成和活动的动态。这一知识对于优化豆类作物对小麦的影响，提高农业的可持续性，减少化肥的使用造成的污染至关重要。

<p> Only around 20 percent of applied P fertiliser is taken up by crops such as wheat, the rest accumulates in soil in fixed forms. Utilisation of this fixed soil P bank could reduce fertiliser applications. Some legumes may have access to part of the soil P bank and improve the growth and P uptake of the following wheat. However, the mechanisms behind this improved growth and P uptake are unclear. In this multidisciplinary international collaboration, we will elucidate the dynamics of P pools and soil microbial community composition and activity in the legume-wheat rotation. This knowledge is crucial for optimising the effect of legumes on wheat to enhance sustainability of agriculture and decrease pollution caused by fertiliser application.</p>
