After the Rio Conference in 1992, Biodiversity became synonymous with protecting the environment.Bioindication has emerged as useful process for environmental evaluation particularly of the soil, whichis a complex entity able to perform a multitude of key functions, vital for life, such as breathing,assimilating nutrients like carbon and nitrogen, transforming and mineralizing organic materials likevegetables and animals, storing substances in reserve in the form of humus. Direct or indirectcontamination of the soil, by inorganic elements and/or organic compounds, can significantly changethe activity and the composition of the organisms living in soil (soil biodiversity) and irreversibly preventthe soil fulfilling its key functions to support the planet’s ecosystems. For example, decline in organicmatter content is closely linked to the loss of soil biodiversity. Recognising that soils contain as muchbiodiversity as the above ground habitats is the catalyst needed to protect this precious resource fromfurther degradation (Montanarella, 2006).
Project BIO-BIO has wanted to give a signal tightly umber of Bioindicators withappearance that cover the field of the Biodiversity for a reading very diversified that cover the threenutritional nets and that in the same time holds in consideration of the temporal appearance with theseasonal influences that can change the replies of the bioindicators, everything supported from arobust chemical-physical soil analyses.
Chemical-physical soil analyses are very important for a complete interpretation of soil quality. Theresults obtained, sole in their fill, will be able to serve to other experts like example to imitate toappraise, in manner exhaustive and entire, the quality and the health of the soil with special attention tothose areas that have an important human pressure.
