Mineral composition of ash leaves (Fraxinus excelsior L.) used as fodder for the ruminants in summer

Résumé

In this paper, our objective was to study the consistency of the mineral composition of leaves from Fraxinus excelsior L. according to their provenance and management, i.e. pollarded vs. high stem trees. The leaves were collected in August 2016 on 7 sites spread out in 3 regions of France. The concentrations in Ca, Na, Fe, Mn and Cu of ash tree leaves, exhibited a high variability (coefficient of variation, C.V.>30%), while the concentrations in N, K, Mg, P, and Zn varied in a lesser extent (C.V.<30%). Pollarded trees exhibited higher N contents (P<0.001) and lower Ca contents (P<0.05) than high stem trees. There was no significant effect of tree management for the other elements. Our results confirm that ash leaves are rich in Ca, mineral of interest for dairy herd feeding. This tree species is also interesting to provide N, Mg, Fe, Zn and Cu.
