The role of earthworms in organic matter cycles,imal residues may be decomposed by the microflora but much organic matter, particularly the tougher plant leaves, stems and root material, does not breakdown without first being disintegrated by soil animals and acted upon by enzymes in their intestines. Earthworms have an important role in this ini

Ansgar Klein,Jupp Legrand,Thomas Leifquare sampling tool, for estimating populations of earthworms by handsorting. He concluded that sixteen sample units of an area of 1/16 m. taken to a depth of 20 cm gave an adequate estimation of a population of medium-sized species. For larger worms and deeper samples, a larger area of sample was required.
