Soil degradation is of worldwide concern since it supports life on Earth, providing ecosystem services such as biomass production, carbon sequestration, water purification, food production, among others. Over decades many anthropogenic activities contributed to its degradation and contamination, including the excessive loading of diverse synthetic organic compounds, metals, agrochemicals, nutrients, and many others. At the midpoint of the International Soil Decade, there are several international entities that standby the development and application of more sustainable agricultural and healthy soil practices and call for the restoration of contaminated soils. These restoration approaches must encompass solutions that themselves do not induce additional pressures to the soil ecosystems, being both sustainable and eco-friendly. In this context, microbial communities may play a leading role in restoring contaminated lands. Accordingly, the CLEAR project aims at evaluating the efficiency of a cost-effective and eco-friendly microbial consortia on metal-contaminated soils collected at the area of Estarreja. It is expected that the use of consortia will come up with a dual benefit for the metal-contaminated soils: (i) will sustain plants/crops using natural components of the soil itself and (ii) will relieve the metal load in soil.
