“…On the other hand, mixed crop plantations consisting of up to only five plant species, supported the most diverse bacterial communities. Agree with Hadi et al (2001) that land conversion from secondary forest to paddy fields (monoculture plantations) led to a decrease in carbon content, together with a decrease in microbial abundance, which is consistent with this findings. Low bacterial diversity in OPP, as seen in this study, can be sensitive to environmental pressures.…”

Abstract. Nusantara RW, Aspan A. 2017. Differentiation of soil organisms at different types of peatland in West Kalimantan,. Peatland conversion could threaten the soil organisms existence which is influenced by soil physical properties. The aim of this research was to analyze the changes in soil organisms of land-use due to the conversion of peatlands in West Kalimantan, Indonesia. The study was conducted in secondary peat forest (SPF), shrub (SB), oil palm plantation (OPP), and corn-field (CF) in Kubu Raya District of West Kalimantan. The stages in this study include observation of water-table depth, soil temperature and analysis of physical properties include bulk density, moisture, and porosity.The results indicated that a decline in colonies of bacteria and fungi in OPP than SPF, 50% and 53% respectively. The decline in the condition of affected water content decrease due to the land conversion of secondary forests into oil palm plantations (22.8%). Additionally characterized by conditions on the water-table depth was deeper and soil temperature was higher in OPP than SPF (16.8%). This condition was the opposite in CF, where both bacteria and fungi increased 53% and 33.3% respectively. The different conditions characterized by the water content, water-table depth, and bulk density even though the temperature was almost the same between OPP and CF.

“…Based on a field study conducted in Jambi, Indonesia, Furukawa et al (2005) reported that CO 2 emissions from tropical peatlands under different land-use management (coconut (Cocos nucifera) field, pineapple (Ananas comosus) field and swamp forest) ranged from approximately around 0.72 to 6.38 g C m −2 day −1 . In addition, field studies conducted in secondary forest and paddy field in tropical peatlands, South Kalimantan, resulted in CO 2 emissions of approximately around 3.36-6.62 g C m −2 day −1 (Hadi et al, 2001). The higher CO 2 emissions recorded in field studies compared with the soil columns likely occur because peat soils in the field have different substrates and microbial populations, which develop in response to long-term differences in water table position and soil managements (Moore and Dalva 1993).…”

“…Lowering the water table increases carbon mineralization and CO 2 and N 2 O emissions but decreases CH 4 emission (Moore and Dalva 1993;Regina et al 1996;Berglund and Berglund 2011). However, no clear relationship was observed between groundwater and CO 2 , CH 4 and N 2 O fluxes in peat soils in the field due to limited frequency of measurements (Hadi et al 2000(Hadi et al , 2001.…”

Recently, large areas of tropical peatland have been converted into agricultural fields. To be used for agricultural activities, peat soils need to be drained, limed and fertilized due to excess water, low nutrient content and high acidity. Water depth and amelioration have significant effects on greenhouse gas (GHG) production. Twenty-seven soil samples were collected from Jabiren, Central Kalimantan, Indonesia, in 2014 to examine the effect of water depth and amelioration on GHG emissions. Soil columns were formed in the peatland using polyvinyl chloride (PVC) pipe with a diameter of 21 cm and a length of 100 cm. The PVC pipe was inserted vertically into the soil to a depth of 100 cm and carefully pulled up with the soil inside after sealing the bottom. The treatments consisting of three static water depths (15, 35 and 55 cm from the soil surface) and three ameliorants (without ameliorant/control, biochar+compost and steel slag+compost) were arranged using a randomized block design with two factors and three replications. Fluxes of carbon dioxide (CO 2 ), methane (CH 4 ) and nitrous oxide (N 2 O) from the soil columns were measured weekly. There was a linear relationship between water depth and CO 2 emissions. No significant difference was observed in the CH 4 emissions in response to water depth and amelioration. The ameliorations influenced the CO 2 and N 2 O emissions from the peat soil. The application of biochar+compost enhanced the CO 2 and N 2 O emissions but reduced the CH 4 emission. Moreover, the application of steel slag+compost increased the emissions of all three gases. The highest CO 2 and N 2 O emissions occurred in response to the biochar+compost treatment followed by the steel slag-compost treatment and without ameliorant. Soil pH, redox potential (Eh) and temperature influenced the CO 2 , CH 4 and N 2 O fluxes. Experiments for monitoring water depth and amelioration should be developed using peat soil as well as peat soil-crop systems.

“…Peatland deforestation, degradation and fires are estimated to have increased carbon dioxide emissions by 0.5 Pg C year −1 [4] [5]. In addition, studies on the impact of agriculture confirm that methane emissions from paddy cultivations are significantly higher (33%) than those from secondary forest [6]. Martikainen, Nykänen [7] found that the rates of mineralization of organic matter and soil microbial nitrous oxide production had also increased in the drier northern peatlands of Finland.…”

In this study, tropical peat swamp soils from Giam Siak Kecil-Bukit Batu Biosphere Reserve (GSKBB) in Indonesia was evaluated to assess the impact of oil palm and rubber plantations on this unique organic soil through comparisons with soils from a natural forest using a polyphasic approach (chemical and molecular microbial assays). Changes in the ammonium, nitrate and phosphate concentration were observed in soils converted to agricultural use. Soil enzyme activities in plantation soils showed reduced β-glucosidase, cellobiohydrolase and acid phosphatase activities (50% -55% decrease). PCR-DGGE based analysis showed that the soil bacterial community from agricultural soils exhibited the lowest similarity amongst the different microbial groups (fungi and Archaea) evaluated (34% similarity to the natural forest soil). Shannon Diversity index values showed that generally the conversion of tropical peatland natural forest to rubber plantation resulted in a greater impact on microbial diversity (ANOVA p < 0.05). Overall, this study indicated substantial shifts in the soil microbial activity and diversity upon conversion of natural peatland forest to agriculture, with a greater change being observed under rubber plantation compared to oil palm plantation. These findings provided important data for future peatland management by relating changes in the soil microbial community and activities associated to agricultural practices carried out on peatland.
