The bacteria and yeasts in the soils of oil palm (elaeis guineensis) plantations
1978
FAPARUSI, S. I.
Soils of two oil palm (Elaeis guineensis) plantations were studied for their bacteria and yeast composition.The pH and moisture and organic matter content of the soils were determined in addition to their mechanical composition. Population counts of the two organisms were done using both the dilution method and the direct-plate-count method at four times of the year (October, December, March, and July).Twelve bacteria and thirteen yeast species were isolated during the investigation. The lowest population figures were obtained during the period of the year with high temperatures and no rainfall. Soil samples from water-logged areas contained low yeast and bacteria populations.
