P4two is a Wageningen Sandwich PhD project that aims to design intercrops with high phosphorus use efficiency based on different preferences for P sources by two crop species.
Intercropping is the simultaneous cultivation of multiple crop species in a single field. Crop species have a variety of strategies to mobilize sparingly soluble P sources. We investigate whether combining plant species with different P acquisition strategies could enhance plant production through complementarity effects on soil P mobilization. We test combinations in pots on different soil types. All experimental work is done in China.
