This land-use conversion caused a reduction of soil organic carbon (SOC) stocks by on average 19% down to 1.2 m over 46 years. Due to the mountainous topography of the region, most rubber plantations include narrow terraces parallel to contours. Manual terrace construction involves cutting of the soil from the upper slope and piling up the removed soil on the soil surface downslope. Soil redistribution by terrace construction may affect SOC dynamics through exposure of the subsurface soil at the terrace inner sides (cut section) and soil burial at the terrace outer edges (fill section).Our study, conducted in southern Yunnan province of China, aimed to quantify SOC stock changes induced by terrace construction. In three rubber plantations aged 5, 29 and 44 years, we systematically sampled the terraces according to soil redistribution zones, and the original sloping areas in between the terraces were used as reference.At the cut section of the terrace, topsoil removal caused a depletion of SOC stocks in the youngest plantation followed by SOC stock recovery in the two oldest plantations. The recovery of SOC stocks at the cut section in the two oldest plantations was attributed to the capacity of the exposed subsurface soil to store new organic carbon inputs from roots and litter, and to sedimentation of eroded topsoil materials from the upper slope. At the fill section of the terrace, soil deposition resulted in higher total SOC stocks compared to the reference position in all plantations. This was due to the deposition of redistributed soil material on top of the original soil surface combined with the partial preservation of carbon in the buried soil. Overall, the increase of SOC in the exposed subsurface soil at the cut sections, and the partial preservation of SOC in the buried soil at the fill sections resulted in higher SOC stocks down to 1.2 m at the terraces compared to the reference positions in the two oldest plantations. Our results imply that terracing may alleviate SOC losses caused by the conversion of secondary forest to terraced rubber plantation."],["dc.identifier.doi","10.1016/j.foreco.2013.10.043"],["dc.identifier.gro","3150143"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/6874"],["dc.language.iso","en"],["dc.notes.status","public"],["dc.relation.issn","0378-1127"],["dc.title","Soil redistribution by terracing alleviates soil organic carbon losses caused by forest conversion to rubber plantation"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]

Studies on the effects of land use changes and land use intensification on soil trace gas emissions were mostly conducted in Latin America and only very few in Asia. Here we present results from Central Sulawesi where profound changes in land use and cultivation practices take place: traditional agricultural practices like shifting cultivation and slash-and-burn agriculture are replaced by permanent cultivation systems and introduction of income-generating cash crops like cacao. Our results showed that N2O emissions were higher from cacao agroforestry (35 ± 10 μg N m−2 h−1) than maize (9 ± 2 μg N m−2 h−1), whereas intermediate rates were observed from secondary forests (25 ± 11 μg N m−2 h−1). NO emissions did not differ among land use systems, ranging from 12 ± 2 μg N m−2 h−1 for cacao agroforestry and secondary forest to 18 ± 2 μg N m−2 h−1 for maize. CH4 uptake was higher for maize (−30 ± 4 μg C m−2 h−1) than cacao agroforestry (−18 ± 2 μg C m−2 h−1) and intermediate rates were measured from secondary forests (−25 ± 4 μg C m−2 h−1). Combining these data with results from other studies in this area, we present chronosequence effects of land use change on trace gas emissions from natural forest, through maize cultivation, to cacao agroforestry (with or without fertilizer). Compared to the original forests, this typical land use change in the study area clearly led to higher N2O emissions and lower CH4 uptake with age of cacao agroforestry systems. We conclude that this common land use sequence in the area combined with the increasing use of fertilizer will strongly increase soil trace gas emissions. We suggest that the future hot spot regions of high N2O (and to a lesser extend NO) emissions in the tropics are those areas where climatic and edaphic conditions allow for intensive agriculture. This scenario is probably preferable over the alternative of agriculture extensification, which would imply a dramatic increase in deforestation rates with accompanying CO2 emissions."],["dc.identifier.doi","10.1029/2007jg000522"],["dc.identifier.gro","3150208"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/6947"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.relation.issn","0148-0227"],["dc.subject","agroforestry; cacao; deforestation; fertilizer; Indonesia; land use change"],["dc.title","Land use change effects on trace gas fluxes in the forest margins of Central Sulawesi, Indonesia"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]

In montane mainland southeast Asia, monoculture rubber plantations cover 1.5 million ha and the conversion from secondary forests to rubber plantations is predicted to cause a fourfold expansion by 2050. Our study, conducted in southern Yunnan province, China, aimed to quantify the changes in soil carbon stocks following the conversion from secondary forests to rubber plantations. We sampled 11 rubber plantations ranging in age from 5 to 46 years and seven secondary forest plots using a space-for-time substitution approach. We found that forest-to-rubber plantation conversion resulted in losses of soil carbon stocks by an average of 37.4±4.7 (SE) Mg C ha−1 in the entire 1.2-m depth over a time period of 46 years, which was equal to 19.3±2.7% of the initial soil carbon stocks in the secondary forests. This decline in soil carbon stocks was much larger than differences between published aboveground carbon stocks of rubber plantations and secondary forests, which range from a loss of 18 Mg C ha−1 to an increase of 8 Mg C ha−1. In the topsoil, carbon stocks declined exponentially with years since deforestation and reached a steady state at around 20 years. Although the IPCC tier 1 method assumes that soil carbon changes from forest-to-rubber plantation conversions are zero, our findings show that they need to be included to avoid errors in estimating overall ecosystem carbon fluxes."],["dc.identifier.doi","10.1371/journal.pone.0069357"],["dc.identifier.gro","3150134"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/9176"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/6865"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.relation.issn","1932-6203"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.subject","Rubber; Forests; Trees; Edaphology; Clay mineralogy; Biophysics; Land use; Bamboo"],["dc.title","Soil Carbon Stocks Decrease following Conversion of Secondary Forests to Rubber (Hevea brasiliensis) Plantations"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","no"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

Our objectives were: (1) to quantify microbial N cycling under long-term N-saturated and limed conditions and (2) to determine the factors controlling the differences in microbial N cycling. Our study site has a long history of high N deposition: greater than or equal to25 kg N.ha(-1).yr(-1) since measurements began in 1971. This was further enhanced by 11 yr (1983-1993) of fertilization (140 kg ammonium sulfate-N.ha(-1).yr(-1)) to create an N saturation plot. Another plot was limed with 30 Mg/ha dolomitic limestone in 1982. In 1999-2000; gross rates of microbial N cycling were measured using N-15 pool dilution techniques. Despite the chronic high N deposition, the control plot showed a tightly coupled microbial N cycle; NH4+ and NO3- immobilization rates were comparable to gross N mineralization and nitrification rates, respectively. These were supported by low levels of NH4+, NO3-, and dissolved organic N (DON) in percolate. Liming increased gross. N mineralization and nitrification rates but did not cause similar increases in microbial biomass or NH4+, and NO3- immobilization rates. In addition, NO3- immobilization rates were somewhat less than gross nitrification rates; relatively high levels of NO3- and DON in percolate were also observed. The N-saturated plot suggested an uncoupled microbial N cycle; NH4+ immobilization rates were lower than gross N mineralization rates, and NO3- immobilization rates were somewhat less than gross nitrification rates. These were corroborated by high levels of NH4+, NO3-, and DON in percolate. The reduced NH4+ and NO3- immobilization rates in the N-saturated plot could be attributed to the measured decreases in microbial biomass, and the low microbial biomass was likely due to decreases in the supply of labile C. Our study demonstrates that while hydrological N input/output budgets can indicate whether or not a forest ecosystem is in a state of N saturation, the microbial N cycle can provide quantitative information on key processes that govern N losses."],["dc.identifier.doi","10.1890/1051-0761(2003)013[0287:SNCIHN]2.0.CO;2"],["dc.identifier.isi","000182669300002"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/95554"],["dc.language.iso","en"],["dc.notes.intern","DOI-Import GROB-476"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Ecological Soc Amer"],["dc.relation.issn","1051-0761"],["dc.rights.uri","http://doi.wiley.com/10.1002/tdm_license_1.1"],["dc.title","Soil nitrogen cycle in high nitrogen deposition forest: Changes under nitrogen saturation and liming"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]
