A team from the University of Rouen came last week to sample soil and vegetation as part of the PLASTRAIT project:
“Plasticity in leaf litter quality of tree species: consequences for soil nitrogen cycling and plant-plant interactions.”
Last Thursday and Friday (June 12-13), Ludovic Henneron, from the Ecodiv unit, accompanied by three colleagues, sampled soil and vegetation on pure oak stands on OPTMix (O12-O214-O593, medium and low density). Other plots from the GIS Coop are also sampled. The aim is to study the nitrogen cycle and leaf traits of the species (tree and undergrowth). They installed five measurement points per plot, marked with a yellow stick. PVC tubes are inserted into the soil and will be retrieved at the end of July. The green oak leaf samples planned by EFNO will be used by Ecodiv for additional measurements.
