Kurzfassung
The proposed project shall contribute to the research cluster “Speciation and allocation of P in soils” of SPP 1685. In our project, (a) the relationship between soil development and spatial heter-ogeneity patterns of total soil P contents and P speciation, (b) P acquisition patterns by Picea abies (Norway spruce) and Fagus sylvatica (European beech) in soils with poor P availability and heter-ogeneous P supply, and (c) effects of heterogeneity patterns of either total P concentrations or P...The proposed project shall contribute to the research cluster “Speciation and allocation of P in soils” of SPP 1685.
