Ecological factors, Sakaerat Environmental Research Station, Thailand
บทคัดย่อ :
Certain ecological factors were investigated for three plant forest habitat types; dry evergreen (DEF), dry dipterocarp (DDF) and ecotone (ECO) at the Sakaerat Environmental Research Station (SERS). The effects of seven habitat types on the physical and chemical properties of soils were investigated. Samples were collected monthly from June 2007 to July 2008. Values for bulk density, porosity, soil pH, soil temperature, total nitrogen and organic matter showed significant differences (p<0.05) between habitat types. The ecotone soil had the highest bulk density and the dry evergreen forest soil the highest soil porosity, while soils from both habitat types were found to be acidic. The dry evergreen forest also had the highest concentrations of organic matter and total nitrogen content, but the lowest concentrations of phosphorus and potassium.
