17 May INRAE researchers were at the Phy2SUDOE S1 site (St Médard d’Eyrans) measuring plant parameters
In April and May 2021, INRAE researchers were working at the Phy2SUDOE S1 site (St Médard d’Eyrans, France) to measure several plant parameters and quantify the phytomanagement progress. The plots at this former wood preservation site were previously managed under the PhytoSUDOE project to remediate the Cu/PAH-contaminated soils.
After several years of sunflower / tobacco crops for the phytoextraction of bioavailable soil Cu and biodegradation of PAHs, the purpose was to assess the culture of other valuable crops such winter barley and agropyrum and the recovery of soil ecosystem services (biomass production, biodiversity of soil microbial community, etc.). Both cereals were sowed in October 2020. Plant parameters were then investigated, and Leaf Area Index (LAI), maximum stem length, and chlorophyll index were measured. For both cereals, the plots amended with either one or two dressings of compost still produce more shoot yield, with higher values for LAI and maximum shoot length as compared to the non-amended plots and basic slag-amended ones.
Plant parameters will be assessed again at harvest time, including the shoot dry weight yield and grain yield. Then plant parts will be analyzed.
