Assessment of Earthworm Distribution in Different Seasons in and around Pondicherry, India
The properties of soil determine the nature of the vegetation present and, indirectly, the number and types of animals. Eleven sites were sampled to study the distribution of earthworms in Pondicherry. Earthworms are probably the most important macro animals in soils (Brady and Weil, 1999). Hence the soil surveyed were analysed for various physical and chemical parameters to correlate their influence on earthworms and vice versa. The surveys were scheduled for four seasons—rainy season (Oct ’02), winter (Jan ’03), early summer (April ’03), and late summer (July ’03).
