Abstract The Indonesian government plans to turn Central Kalimantan into a national food barn by planting rice in several places, including shallow peatlands. Tropical peatlands actually have limited potential for agricultural use because the growing medium some cases is not conducive root development, waterlogged soils that poison plants. physical, chemical, and biological properties of water ...

Tropical peatland stores a large amount of carbon (C) and is an important C sink. In Malaysia, about 25% the area has been converted to oil palm plantation where drainage, compaction groundwater table control are prerequisite. To date, relationship between land emission from tropical scarcely studied. understand effect on soil dioxide (CO2) methane (CH4) flux peatland, laboratory column incubat...

Forestry harvesting on peats is known to result in significant losses of soil phosphorus (P) to adjacent waters, and the issue is becoming an increasingly serious concern as peatland forest stocks mature and reach harvestable age. One potential solution could be the use of low-cost P recovery techniques based on the chemical precipitation and/or adsorption of the dissolved fraction of soil P, w...

Abstract The Indonesian government plans to turn Central Kalimantan province into a national food barn by planting rice paddies in several places, including shallow peatlands. Tropical peatlands have limited potential be used as agricultural land since the growing media some cases, is not conducive root development, saturated-water soil that poissons plants. Aquatic invertebrates can indicators...

Abstract Amazonian swamp forests remove large amounts of carbon dioxide (CO 2 ) but produce methane (CH 4 ). Both are important greenhouse gases (GHG). Drought and cultivation cut the CH emissions may release CO . Varying oxygen content in nitrogen-rich soil produces nitrous oxide (N O), which is third most GHG. Despite potentially tremendous changes, GHG from wetland soils under different land...

Abstract This study quantified CO 2 emissions from tropical peat swamp soils in Brunei Darussalam. At each site, soil was collected areas of intact and degraded flux, total organic content were measured ex situ. Soil (~20–99%) not significantly different between forest samples. flux higher for samples than (~1.0 vs. ~0.6 μmol m −2 s −1 , respectively) but did differ among locations. From our la...

The present study aimed to demonstrate the relationship of some environmental factors, vegetation greenness index (NDVI) and land surface temperature (LST), with the seasonal variations of Mansonia bonneae and Ma. uniformis in Khosit Subdistrict, Narathiwat Province. It was found that the Mansonia population lagged one month behind but correlated positively to NDVI, LST and rainfall. A rise in ...

The cultivation of oil palm on peat swamps in Malaysia has changed the water quality and aquatic ecosystems. We determined fish species composition conditions at a disturbed swamp, i.e., plantation, Kuala Langat swamp reserve forest, Selangor. Fishes were collected via gill net five selected drains during dry wet seasons between August 2014 January 2015. In-situ (electrical conductivity (EC), d...
