Local and systemic effects of phosphorus and nitrogen on nodulation and nodule function in Alnus incana [link]Paper  doi  abstract   bibtex   
Phosphorus (P) and nitrogen (N) effects on nodulation, nitrogenase activity and plant growth were studied in the root‐hair‐infected actinorhizal plant Alnus incana (L.) Moench. A split‐root experiment, as well as a short‐term experiment with entire root systems and a broader range of P concentrations, showed that P effects were specific on nodulation and not a general stimulation via a plant growth effect. These results indicate that nodule initiation and nodule growth have a high P demand. The split‐root assay, comprising seven combinations of two N and two P levels, showed that P could counteract systemic N inhibition of nodulation, but did not counteract N inhibition of nitrogenase activity.
