Soil Fungi in an Over-burned Tropical Rain Forest in Bukit Bangkirai, East Kalimantan

Abstract

A study was conducted in Bukit Bangkirai forest, East Kalimantan, to understand the impact of forest fire on the existence of soil fungi. Three permanent plots were used for the research, i.e. undamaged plot (K), lightly damaged plot (LD), and heavily damaged plot (HD). Each plot was 1 ha and divided into 100 sub-plots (10 m x 10 m). For observation of soil fungi, in the center of the five randomly selected sub-plots from each plot was made a sampling plot (2 m x 2 m). After removing the organic matter surface (O layer), soil sample was collected from top layer (A) and second layer (B) in each of the five sampling plots. Soil fungi were isolated using dilution plate method and they were incubated at room temperature (27-28 o C). This process was replicated two times for each soil sample. The result indicated that forest fire decreased the diversity and population of soil fungi. The highest soil fungi population was found in the undamaged (K) plot at the top layer (A) (389.0 colonies/mg dry soil), while the lowest population was in the lightly damaged plot (LD) at the second layer (B) (12.3 colonies/mg dry soil). Gongronella butleri was dominant species in the area of the tropical rain forest which was fired in Bukit Bangkirai, East Kalimantan.

“…Di antara 15 marga jamur tersebut, Aspergillus merupakan marga jamur yang banyak ditemukan, yaitu 13 jenis diikuti Penicillium dan Fusarium masing-masing adalah 7 dan 3 jenis. Aspergillus flavus Link ex Gray dan A. niger van Tieghhem ditemukan pula di tanah hutan bekas terbakar di Bukit Bangkirai, Kalimantan Timur (Suciatmih, 2006b) dan tanah hutan bekas terbakar di Wanariset Samboja, Kalimantan Timur (Suciatmih, 2006a). Gliocladium virens Miller, Gidden & Foster dilaporkan pula terisolasi dari lumpur mangrove Okinawa, Jepang (Ito dan Nakagiri, 1997a), rizosfir tanaman mangrove Okinawa, Jepang (Ito dan Nakagiri, 1997b), tanah hutan bekas terbakar di Bukit Bangkirai, Kalimatan Timur (Suciatmih, 2006b) dan tanah mangrove Muara Angke, Jakarta (Nakagiri et al, 2005 Nakagiri et al (2005) dari areal mangrove Muara Angke, Jakarta.…”

Impact of land and forest fire on soil fauna diversity in several land cover in Jambi Province, Indonesia

“…Forest and land fire causes the dying, decreasing, and disturbing the population of the soil biology diversity (microorganisms and microorganisms), which are essential in the forest and land ecosystem, especially to maintain and improve the soil fertility (quality). (Barrow 1991, Suciatmih 2006, Saharjo and Nurhayati 2006, Saharjo et al 2011 . Impacted soil biology (especially soil fauna) by forest fire needs significant time to recovery.…”

In vitro antagonistic activity evaluation of some selected fungi isolated from burned soils in Mila region (East of Algeria)

“…The fact that the soil has a low rate of salt and lime (Ca +2 ) could exclude their negative effect on the activity of soil microorganisms. Suciatmih (2006) found that a significant positive correlation existed between the fungal population and the total organic carbon content. Waid (1960), listed temperature, humidity, CO 2 , oxygen concentration, size of the soil pores, longevity of fungal mycelium, interaction between soil fauna and soil fungi and soil reaction as factors that may influence growth and production of the mycelium of fungi in the soil.…”

“…According to Suciatmih (2006), the forest fire leads to a reduction and possibly an elimination of soil fungi. Chet (1984) reported studies on mode of action of Trichoderma used for biological control against Rhizoctonia solani in the case of cotton and strawberry cultivation, the results highlighted the importance of mycoparasitism phenomenon in the effectiveness of Trichoderma.…”
