Abstract:
A field survey was carried out on farmer land areas in Northeast Thailand where earthworms have been inhabited. Methodology being used was a grid method of 10×10 m plots in four different inhabitancies, i.e. native dipterocarp forest, tamarind orchard, natural grazing areas and sugarcane plantation. The results showed that earthworm inhabitants were largely found in soils with organic matter contents (OM%) ranging from 0.40-0.89% and soil pH values of the studied sites ranging from 4.68-6.29 whilst electrical conductivity (EC) values of soil locations were ranging from 52.9-94.0 μMho/cm. There were no clear trends on earthworm (Pheretema sp.) distribution have been recorded yet it seems more likely that organic matter, soil moisture contents, soil disturbances and seasonal changes had its effects on earthworm distribution. Variation in soil characteristics had no effect on earthworm distribution in Northeast Thailand and it was not considered as a limiting factor to proliferation of the earthworms.
