Description Certain plant species release root exudates with high concentrations of carboxylates in response to phosphorus limitation. These carboxylates mobilize P from less available P sources. However, the concentrations of these carboxylates in root exudates are very difficult to measure in the field. Literature that suggests that the leaf manganese concentration can be used to find plant species or to select for genotypes that are more efficient at acquiring P when soil P availability is low. The rationale for this is that carboxylates mobilise not only P, but also a range of micronutrients including Mn. We doubt whether this true. The aim of this project is therefore to find out if and how model root exudates indeed mobilize P and Mn at the same time, and how this is soil type dependent.
