Tropical peatlands have different characteristics as compared to temperate peatlands in terms of organic materials and topography. It is important to understand the soil characteristics for improving crop management practices. A study was conducted to investigate the effects of different types of peat on soil carbon dioxide (CO‚‚) emissions and oil palm yield in Sarawak. The study area was classified as Naman (Oa) and Kenyana (Oawu) series using the Malaysian Unified Classification of Organic Soils (MUCOS). Soil CO‚‚ efflux was determined by using a portable CO‚‚ analyser at monthly intervals from eight observational plots setup in each 10 ha study plot. The oil palm fresh fruit bunch (FFB) yield was recorded since the first year of harvest (i.e. after about 30 months field planting). Results showed that the average soil CO‚‚ efflux was the highest in Naman series plot (4.890.36 mol CO‚‚ m s) compared to Kenyana series plot (4.440.37 mol CO‚‚ m s).However FFB yield was recorded 40 higher at Naman plot compared to Kenyana plot. Higher FFB yield in Naman plot was related to its soil consisting of sapric materials that have more nutrients available for the crop while Kenyana plot consisted of sapric materials together with undecomposed wood that might hinder the palm growth. This study suggests that different types of peat have significant effects on oil palm yield and soil CO‚‚ emissions. The site-specific and peat soil management based on its characteristics is important for oil palm growth and performance especially for enhancing FFB yield and improving environmental management.

Abstract

Tropical peatlands have different characteristics as compared to temperate peatlands in terms of organic materials and topography. It is important to understand the soil characteristics for improving crop management practices. A study was conducted to investigate the effects of different types of peat on soil carbon dioxide (CO‚‚) emissions and oil palm yield in Sarawak. The study area was classified as Naman (Oa) and Kenyana (Oawu) series using the Malaysian Unified Classification of Organic Soils (MUCOS). Soil CO‚‚ efflux was determined by using a portable CO‚‚ analyser at monthly intervals from eight observational plots setup in each 10 ha study plot. The oil palm fresh fruit bunch (FFB) yield was recorded since the first year of harvest (i.e. after about 30 months field planting). Results showed that the average soil CO‚‚ efflux was the highest in Naman series plot (4.890.36 mol CO‚‚ m s) compared to Kenyana series plot (4.440.37 mol CO‚‚ m s).However FFB yield was recorded 40 higher at Naman plot compared to Kenyana plot. Higher FFB yield in Naman plot was related to its soil consisting of sapric materials that have more nutrients available for the crop while Kenyana plot consisted of sapric materials together with undecomposed wood that might hinder the palm growth. This study suggests that different types of peat have significant effects on oil palm yield and soil CO‚‚ emissions. The site-specific and peat soil management based on its characteristics is important for oil palm growth and performance especially for enhancing FFB yield and improving environmental management.
