ObjetivoTo study whether the addition of rhamnolipids (cause) improves Cu phytoextraction (effect) in Cu-contaminated soils (population).

DescripciónSamples are taken from two different soils (Coria and Constantina), which are then artificially contaminated with Cu, distributed in pots, and left to age for 45 days. Then, barley and mustard seeds are sown, fertiliser is added, and JBR-425 rhamnolipid is added after 15 days. After 30 days, the Cu content of plant biomass and the availability of Cu in soil are analyzed by two different methods: extraction with CaCl2 and EDTA. Cu was applied in three concentrations: 0, 500 and 1000 mg/kg, so 6 treatment groups were obtained combining the 3 concentrations of Cu with the addition or not of JBR-425. The control group was taken as the one that was neither contaminated with copper nor added with JBR-425.
