Sengon (Falcataria moluccana), a fast-growing timber tree that naturally grows on mineral soils, is currently promoted in peatlands. This study aimed to (1) experimentally test the response of sengon seedlings in waterlogged conditions in the nursery; (2) describe and analyze the biophysical condition of a sengon plantation and its growth; (3) describe sengon farm practices on peatlands; and (4) identify key actor’s perception on planting sengon on peatlands. This study combined an experiment in nursery, field measurements, and key-informant interviews. The nursery experiment showed that peat soil affected seedling’s growth: survival rates decreased by 25–33% after 3 months of inundation. Sengon growth at age 1–5-years-old in peat soil was slower than that on mineral soils. Sengon growth in peatland was influenced by peat depth and peat maturity. Sengon plantation in Central Kalimantan was driven by market availability and industrial wood demand. Fourty-three percent of respondents thought sengon does not grow well in peat soils, but 57% of respondents thought that additional soil treatment will enhance site suitability. Based on key-informants’ experience, 64% disagree with sengon development in peatlands. Our study provides evidence that sengon is predominantly not suitable to be planted on peatlands. Therefore, cautions need to be taken when planting sengon on peatland areas.

Rattan agroforest is a swidden cultivation systems, which apply slash-burning and fallow rotation in its development. This system is commonly practised by local farmers of Dayak in Central Kalimantan. The objective of the study was to assess soil characteristics of 5 land use types, namely forest, secondary forest (baliang), young rattan agroforest (bahu), complex ruber-rattan agroforest (CRR), and simple rubber agroforest (SR) in two villages in Katingan. The method used in the study was regular methods of soil analysis, such as pH (H2O &KCl), Corganic(Walkley & Black), Pavailable (Bray), Ntotal (Kjeldahl), and soil texture. The result showed that in the top layer (0-10 cm depth), forest has the highest C/N ratio, but the lowest ratio of Corg/Cref compare to others. Forest has the lowest Pcontent (4.02 ppm), while SR has the highest Pcontent (12.06 ppm). CRR and SR tends to have higher clay content than sand content. In general, farming systems determine characteristics of the soils. Forest conserves soil characteristics, while management that applied by farmers in the agroforestry system may improve soil fertility.

We transplanted Shorea selanica and Shorea lamellata seedlings that either had or had not received ectomycorrhiza (EcM) Scleroderma columnare inoculum, commercially available and prescribed as standard practice in nursery, into rubber gardens of different age and plot history. The objective was to assess whether or not absence of fungal inoculants restricted seedling survival, growth, nutrient uptake and EcM formation in the first 2 years after out-planting in Jambi. Inoculation with EcM fungi in nursery had only limited positive effects on growth in height and diameter or N and P uptake, but it enhanced survival in the period 6–24 months after outplanting in all plots. With or without nursery stage inoculation, S. selanica and S. lamellata can be used for enrichment planting or reforestation in Sumatra as the species respond well to high light intensities. Presence of up to five morphotypes of EcM confirmed the availability of inoculum also in second generation rubber agroforests. Internal transcribe spacer sequencing revealed no S. columnare could be identified from the ectomycorrhizal roots of S. lamellata and S. selanica.
