How do legumes improve phosphorus uptake of the following wheat?

<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>
