Presentation in the Iberian Congress of Soil Science

“The soil as sustainable resource for the bioeconomy” was the theme for the VIII Iberian Congress of Soil Sciences, held at San Sebastián/Donosti, during 20-22 June 2018.

Researchers of the projects RECARE and RESTECO contributed to the 3rd session, devoted to “Protection and restoration of soils”, with the comunication titled “Soil restoration strategies in the Guadiamar River Valley. Evaluation of 20 year of monitoring after the Aznalcóllar mining accident”.

This work is a review of the 20-year monitoring of contaminated and remediated soils, after the Aznalcóllar mine-spill. The application of soil amendments (sugarbeet lime and biosolid compost) was evaluated and results of 14-year changes of pH and organic carbon were shown.

At a large scale, in a soil survey along the Agrio and Guadiamar rivers, high level of Cd and Zn were detected in certain spots of channel and river banks.
