“…Such similar trend was also reported where higher number of large trees over 30 cm dbh will contribute to the higher aboveground biomass and carbon for primary forest when compared to the secondary forest in Singapore (Ngo et al 2013). Furthermore, this could be due to the effect of higher site fertility index at similar site as reported by Akbar et al (2010) compared to other study plots.…”

The loss and degradation in tropical forest region are some of the current global concern. Hence, these issues elevated the role of rehabilitated forests in providing ecological products and services. The information on the carbon stock is important in relation to global carbon and biomass use, but lacking from the tropical region. This paper reports the assessment of tree and soil carbon stock in a chronosequence rehabilitated tropical forest stands in Malaysia. The study site was at the UPM-Mitsubishi Forest Rehabilitation Project, UPMKB. 20×20 m plot was established each and assessed in 2009 at 1-, 10-and 19-year-old sites while an adjacent ±23-year-old natural regenerating secondary forest plot was established for comparison. The overall total carbon stock was in the order of 19-year-old＞±23-year-old＞ 10-year-old＞1-year-old. When forest carbon stock is low, the soil component plays an important role in the carbon storage. The forest carbon recovery is crucial to increase soil carbon stock. The variations in the carbon stock showed the different stages of the forest recovery. Species survived after 19-years of planting are potential species for carbon sequestration activities in rehabilitated forest. Human intervention in rehabilitating degraded forest areas through tree planting initiatives is crucial towards recovering the forest ecological role especially in forest carbon stock capacity.

“…The resultfrom this study also showed that there was low accumulation of organic matter after planting. After harvesting or clearing, organic matter from the soil decreased because of no input of organic matter from the plant since it was harvested (Akbar et al, 2010). Similar results were reported by Nye and Greenland (1964); Kedawang et al (2004) and Ilstedt et al (2004); soil organic matter decline rapidly after the soil is exposed due to harvesting or clearing activities.…”

“…The acidity occurring in the forest soils was due to the presence of Al and H. According to Zaidey et al (2010), the Al concentrations and organic matter influenced the soil acidity. Moreover, the acidity may be caused by water deficiency due to drought (Akbar et al, 2010). When this occur, root mat develop on the surface layer resulting in high carbon content.…”

An assessment of forest rehabilitation program in relation to soil fertility status by using soil indices could provide fundamental information on soil suitability for species preferences and improve the effective technique for future rehabilitation program in tropical rainforests. This study was conducted in order to characterize the soil properties and identifying the soil fertility status of rehabilitated and secondary forests. Soil samples were collected in year 2009 at rehabilitation forests (20 years after planting) and secondary forest of Nirwana Forest Reserve, Universiti Putra Malaysia (UPM) Bintulu Campus, Sarawak, Malaysia. The rehabilitation plots were planted with mixed dipterocarp and non-dipterocarp species since 1991. Prior to conversion of the areas into various land use types, the rehabilitation and secondary forests areas were considered as natural forests and subsequently subjected to forest logging with Selective Management System (SMS) in 1980s.The plot size for each site was 20×20 m for 18 experimental sites (at different ages after planting) were established, followed by soil sampling at 0-15 cm and 15-30 cm depth randomly using soil auger. Standard soil analysis for physical and chemical properties was used to analyze the soil samples. The soil fertility status was evaluated using two indices, namely Soil Fertility Index (SFI) and Soil Evaluation Factor (SEF) for both rehabilitated and secondary forests. The results showed that there were significant differences (p<0.05) in pH (water and KCl), exchangeable Mg, Na, Al and ammonium and granule composition (clay, silt and sand) between depths. The PCA result of 70% total variability (OM, TOC, TC and CEC) score in PC1 shows positive relationship, explaining nutrients in the soil stored in the organic matter in the surface soils. The correlation analysis indicated that there were positive relationship (p<0.05) between OM and TC, CEC and exchangeable Al for surface soils. We found that the selected physico-chemical properties had a significant differences based on the age of planting of rehabilitated forests. For subsurface soils, correlation between exchangeable Al and OM and CEC shows strong positive relationship, indicating that negative charge derived from organic materials plays important roles for cation retention capacity. The SFI and SEF for rehabilitation forests showed higher value as compared to secondary forests, indicating forest rehabilitation had improved the soil fertility status of degraded forestland. In conclusion, both rehabilitated and secondary forests have significant differences based on the selected physical and chemical properties. Moreover, the soil fertility status at rehabilitated plots was higher than secondary forest, which is proved that the forest rehabilitation technique is a suitable planting technique for rehabilitating and replenishing soil fertility status of abandoned degraded shifting cultivation land.

“…The CEC recorded in this study was very low with a value of 3.94 cmol c kg -1 soil which was due to low clay content and similar to other study found by (Malisa et al, 2011;Roslan et al, 2011) reported that the CEC values on a BRIS soil less than 5 cmol c kg -1 .This means that the bases are easily lost via leaching during rainy season. This is similar to Akbar et al (2010) who reported that different in CEC values due to soil erosion or leaching. Parfitt et al (1995) also reported that lower contents of clay and loam in the soil lead to a low CEC values.…”

The demand for kenaf in the world increases rapidly by the years. Cultivation of the crop in Malaysia is a challenging task, especially when kenaf is grown on sandy soils with low fertility, such as the BRIS Soils (Beach Ridges Interspersed with Swales). A pot study was conducted in a glasshouse at Universiti Putra Malaysia to evaluate the potential of inorganic and organic fertilizers or their combination for growing kenaf on very sandy BRIS Soils, using variety V36. There were altogether sixteen treatments: (T Results showed that application of inorganic material or organic fertilizer in combination with chemical fertilizer (T 2 and T 16 ) improved soil fertility, which are reflected by the increase inexchangeable K, Ca and Mg, CEC, total N, total C and available P. The highest kenaf growth was observed in T 15 treatment.Application of biochar, zeolite or chicken manure alone on the soils did not result in better kenaf growth compared to the control. Zeolite and biochar should be applied with other fertilizers or organic substrate to obtain a positive yield of crop and increase the soil properties. In addition, more studies on the application of chicken manure at different ratios should be conducted to obtain the best yield. Combination treatment, T 15 (NPK + biochar + zeolite) can be suggested to the farmers especially cultivation of kenaf on sandy BRIS soil in order to obtain the best kenaf growth performance and indirectly reduce excessive use of chemical fertilizers.
