Abstract

This study aims to analyze burrowing activities of endogeic earthworms Pontoscolex corethrurus on some soil types namely garden soil (mineral soil), peat soil and sandy soil. The earthworm movement observed include vertical and horizontal movement. This study was conducted in the laboratory of Ecology, University of Bengkulu from January to March 2015. The parameters observed in this study is a long period of earthworms enter to the media, long period of earthworm reaches a depth of 20 cm and a length of a pore or hole formed by earthworms P. corethrurus. The results showed that the ability of earthworms to create pores or holes in the soil through their movement activities varied on three types of soil. Long period of earthworms to enter to three kinds of soil, is not significantly different statistically (at 5.62 minutes on peat soil, at 6.11 minutes on garden soil and 5.62 minutes on peat soil). In all three media, the fastest vertical movement of earthworms to reach the bottom of a glass container (depth 20 cm) is in the garden soil media (14.5 minutes) and significantly different on peat soil (14.75 minutes) and sandy soil (16.24 minutes). The longest vertical pores formed by earthworms is on sandy soil with a pore length of 16.24 cm and is significantly different from lenght of vertical pores on garden soil 13.25 cm and 12.64 cm on peat soil. The longest horizontal pores is on garden soil (7.33 cm) and significantly different from horizontal pores on peat soil (6.14 cm) and on sandy soils (3.61 cm). The vertical pores formed by the earthworms P. corethrurus were longer than the horizontal pores.
