Analisis Karakteristik Tanah Busut Rayap Di Dalam Ekosistem Hutan Tropis Dataran Rendah

---

Subterranean termites are abundantly present in the tropical regions, including in lowland tropical forest ecosystems. The eusocial insects live in colonies that build subterranean nests that cause ground surface to expand into mounds or domes. They alter land surface flatness and the activities of the insects have been reported influencing the physical and chemical characteristics of the soils. The objective of the present study was shape, dimension, and the physical and chemical characteristics of the soils. Data collection was conducted in a lowland tropical forest remnant in Minas area, Riau Province. A total of 33 mounds were randomly selected out of 198 mounds encountered during the exploration. They were all “dome-shaped” with varying dimensions, with an average basal diameter of 430 cm, average peak height of 110 cm, average length of arch of 640 cm, and average surface area of 19 m2. The upper soil layers of the mounds had an average penetration resistance of 854 kN/m2, average moisture content of 32,7%, average bulk density of 1,3 g/cm3, and average porosity of 0.50 g/cm3. The soil layers consisted of an average of 41,2 % sand, 33,3 % clay, 25,6% silt, 4,2 % organic mater content, 0,14% nitrogen content, 0,02% phosphorus content, 0,12% potassium content. Although the presence of such termite mounds averagely expanded the ground surface 4.5 m2 or 31%, no significant differences were observed between the upper soil layer of the mounds and the soils of their suroundings.

Key findings: dimension, penetration resistance, bulk density, texture, organic mater content, nitrogen content
