Population dynamics of earthworms in relation to soil physico-chemical parameters in agroforestry systems of Mizoram, India.
TLDR
In this paper, earthworm population dynamics was studied in two agroforestry systems in the tropical hilly terrain of Mizoram, north-east India, over a period of 24 months, from July 2002 to June 2004.Abstract:
Earthworm population dynamics was studied in two agroforestry systems in the tropical hilly terrain of Mizoram, north-east India, over a period of 24 months, from July 2002 to June 2004. Two sites of agroforestry situated at Sakawrtuichhun (SKT) and Pachhunga University College (PUC) campus, Aizawl, having pineapple as the main crop, were selected for detail studies on population dynamics. Five of the total twelve species of earthworm reported from the state were recorded in the study sites. The density of earthworm ranged from 6 to 243 ind.m(-2) and biomass from 3.2 - 677.64 g.m(-2) in SKT. Comparatively the density and biomass in PUC, which is at relatively higher altitude were lowerwith a range of 0 to 176 ind.m(-2) and biomass from 0 - 391.36 g.m(-2) respectively. Population dynamics of earthworm was significantly correlated with rainfall and physical characters of the soil. Earthworm biomass was significantly affected by rainfall and moisture content of the soil. The influence of chemical factors was relatively less.read more

Effect of abiotic factors on the distribution of earthworms in different land use patterns
TL;DR: Earthworm biodiversity and distribution have been found to be positively correlated with type of vegetation and moisture content at the different collection sites and also varied according to soil habitat, soil tillage and land used pattern.

Impact of soil physico-chemical properties on distribution of earthworm populations across different land use patterns in southern India
TL;DR: It was noticed that the distribution of earthworm was higher in forest lands and followed by grasslands having high organic manure rather than agricultural land, and a significant impact of habitat conditions on the soil physico-chemical properties as well as earthworm density was revealed.
