Soil biological diversity.

 

Soil biological diversity reflects the variability among living organisms including a myriad of organisms not visible to the naked eye, such as microorganisms (e.g., bacteria, fungi, protozoa) and meso-fauna (e.g., nematodes, acari and springtails), as well as the more familiar macro-fauna (e.g. earthworms, ants and termites). The most recommended methods for soil biodiversity include the counting and identification of macro and mesoorganisms by a trained person, following extractions in the laboratory (e.g., Berlese funnel, Baermann funnel or pitfall traps in the field). A regular genomic analysis biodiversity to be assessed more accurately at the microbial level. It is recommended to associate at least one of these methods with the respiration rate mentioned in the recommended indicators in order to better interpret the values obtained.
