Formatted Abstract/Summary
Mine soils stabilization is an in situ remediation method that uses inexpensive amendments to reduce heavy metals availability and increase soil organic matter, nutrients and water retention in polluted soils. We tested the long-term effects of several amendments (pig manure, sewage sludge and marble mud) on the immobilization of heavy metals and improvement in soil physico-chemical properties in abandoned tailing ponds from SE Spain affected by former mining activities. Results showed that an initial increase in pH close to neutrality occurred and remained practically stable with time. However, soil organic matter decreased owing to mineralization and leaching. Total contents of heavy metals remained stable for a long time, but bioavailable metals decreased in the amended plots. However, increments in Pb and Zn in El Lirio, and in Cd and Zn in Brunita in the amended plots after 5 years of monitoring were observed. The main reasons could be slight decreases in pH, water and wind erosion of surface particles that provokes shifts in bioavailable metals, decrease in soil organic matter, which initially immobilized metals, and release of root exudates by colonizer plants in amended plots, which tend to mobilize nutrients and as a consequence metals.
