Summary

Below-ground plant N (BGN) of grain legumes is an important N pool for subsequent crops. Especially the easily available rhizodeposits (RD) provide an important N input, which might also be relevant in mixed stands. The objective of the present study was to estimate the time course of the BGN, especially RD-N, and the effect of mycorrhization on RD-N. Therefore, the quantity of RD-N of peas with and without mycorrhiza (Frisson and P2) was estimated at four different growth stages. The results show that the relative contribution of BGN to total plant N was equal in both varieties during the growing season. The contribution of RD-N to total plant N decreased over time. Mycorrhization did not affect the quantity of N-rhizodeposition. Consequences for mixed cropping systems will be further investigated in the project.
