Abstract : One of the key issues in compost research is to assess the quality and maturity of the compost. Biological parameters, especially supported mesofauna, have multiple advantages for monitoring a given system. The mesofauna of compost includes Isopoda, Myriapoda, Acari, Collembola, Oligochaeta, Tardigrada, Hexapoda, and Nematoda. This wide spectrum of organisms forms a posh and rapidly changing community. Up to this, none of the dynamics, in reference to the composting process, of those taxa are thoroughly investigated. However, from the mesofauna, only nematodes possess the specified attributes to be potentially useful ecological indicators in compost. They occur in any compost heap that’s investigated and in virtually all stages of the compost process. Compost nematodes are often placed into a minimum of three functional or trophic groups. They occupy key positions in the compost food web and have a rapid respond to changes in the microbial activity that is translated in the proportion of functional (feeding) groups within a nematode community. Furthermore, there’s a transparent relationship between structure and function: the feeding behavior is definitely deduced from the structure of the mouth cavity and pharynx. Thus, evaluation and interpretation of the abundance and function of nematode faunal assemblages or community structures offers an in situ assessment of the compost process.
