<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>

<p> 只有大约20%的磷肥被小麦等作物吸收，其余的以固定形式积累在土壤中。利用这种固定的土壤磷库可以减少化肥的施用。某些豆科植物可以利用部分土壤磷库，促进下茬小麦的生长和磷的吸收。然而，这种改善生长和磷吸收背后的机制尚不清楚。在这个多学科的国际合作，我们将阐明动态的磷库和土壤微生物群落组成和活性的豆类-小麦轮作。这些知识对于优化豆类对小麦的影响，提高农业的可持续性和减少化肥施用造成的污染至关重要。lt;/p>
