Abstract
To investigate abundance of soil organisms in the ginseng cultivation, we have selected 6 different cultivated lands in Jinan-gun, Jeollabuk-do. The microarthropods were assessed on the basis of 3,101 individuals collected between April and November 2008. The taxonomic composition and abundance of microarthropods were as follows: Acari 44.9%, Collembola 50.1% and others 5.0%. Density increased at the cast and 4 year point, and the population of microarthropods was high in April and May, but low in July and August. Acari/Collembola ratio was approximately 0.90%. There was no correlation between soil factors and microarthropods. The density of soil actinomyces represented a monthly average 0.3~0.9×106 cfu g-1, and fungi tended to increase and decrease regularity at each spots, where highest decrease was observed in August and September. The density of bacteria was 1.1~9.6×106 cfu g-1 in each period and those in June and August were much higher than after August. The distribution of fluorescent Pseudomonas showed regular tendency in early survey periods but did not appear in significant numbers after July.
