Heavy reliance on organosynthetic chemical methods to control agricultural pest
tends to deteriorate and lower fertility of soil. We studied annual occurrence of earthworm in environment-
friendly agroecosystem and attempted to determine the degree of soil contamination.
Candidate bioindicators of earthworm in agroecosystem were selected through analysis of earthworm
diversities. Depending on the degree of pesticide use, the fields were devided into conventional,
less-pesticide, pesticide free, and organic fields. A nearby field not in agricultural use was
chosen as a control. This study was carried out in the greenhouses (lettuce and grape) in 2006 and
in orchards (apple, pear, peach, citrus and grape) in 2007. Earthworm was collected from 50×50
×10 cm3 of respective soil. We found 11 species from 5 genera and 3 families, and 12 species from
4 genera and 3 families in the greenhouses and in orchards, respectively. The contents of organic
matter in soil in the greenhouses were variable but quite less so in orchards. Amynthas heteropodus
occurred most frequently in both sites suggesting that it could be adopted as a bioindicator in
agroecosystem in Korea.
