Earthworm Biodiversity in an Arid Region of Rajasthan, India

Among the dirt fauna, night crawlers have a significant job to improve soil surface. The dirt surface assumes a significant job in water holding limit. Night crawlers have a capacity to improve soil qualities. It adds to the breakdown of natural issue and discharge plant supplements (Edwards and Bohlen, 1996). Worms are likewise considered as helpful marker of the wellbeing of soil environment (Edwards and Bohlen, 1992) concerning their job in soil richness through fracture and stirred up the dirt with mineral molecule, improving microbial action to breakdown plant natural matter.The commitment of night crawlers in soil turnover, structure arrangement and fill in as a ripeness enhancer in various way. Night crawlers are helpful in land improvement and natural waste administration (Edwards and Baker, 1992; Lavelle and Martin, 1992; Johnson, 1997; Villenave et al. , 1999). The conveyance and populace thickness of different night crawler species have been associated with soil type and h orticulture land use (Haynes et al. , 2003; Sbrina et al. , 2009). The biodiversity of night crawlers is impacted by physical, synthetic and organic properties of soil and climatic states of habitats.Earthworm’s biodiversity is legitimately influenced by soil qualities (Edwards and Lofty, 1977). These people group impacting factors are soil pH, natural issue, nitrogen, C/N proportion, soil dampness and soil surface. Biodiversity is considered HR (Heywood, 1996). As of late, numerous researcher examined the biodiversity and dispersion of night crawlers in the various pieces of the world (Blakemore, 2000, 2002, 2003; Change and Chen, 2004,2005; Blakemore et al. ,2006; Sautter et al. , 2006; Ghafoor et al. , 2008).Present examination was done in Bikaner region, which is situated in Thar desert of Rajasthan extending 28. 01â ° N 73. 19â ° E. . The normal downpour fall here is 10† to 15† as it were. Accordingly, climatic conditions are antagonistic for life forms. A large portion of its territory is inundated with tube wells and Indira Gandhi channel. Because of unfavorable conditions from an extensive stretch, there is as yet a couple of data about biodiversity and living spaces. The current examination will uncovered new essential data for additional exploration on night crawlers and its nature and use of worms in agribusiness division.
