Ammonium and nitrate depositions were simulated on four treatments (cultured and non-cultured) and each treatment was labeled with either 15N-NH4 + or sN-NO3⎯. Total recovery rates of the applied 15N in the whole system accounted for 74.9% to 67.3% after 15N-NH4 + and 85.3% to 88.1% after 15N-NO3⎯ in cultured and non-cultured treatments, respectively. The main sink for both 15N tracers was the forest soil (including forest floor), where 34.6% to 33.7% of 15N-NH4 + and 13.1% to 9.0% of 15N-NO3⎯ were found in cultured and non-cultured treatments, respectively, suggesting strong immobilization of both N forms by heterotrophic microorganisms. Nitrogen immobilization by microorganisms in the forest soil (including forest floor) was three times higher when 15N-NH4 + was applied compared to 15N-NO3⎯. The preferential heterotrophic use of ammonium resulted in a two times higher retention of deposited 15N-NH4 + in the forest soil as compared to plants. In contrast, nitrate immobilization in the forest soil was lower compared to plants, although statistically it was not significantly different. In total the immobilization of ammonium in the plant-soil system was about 60% higher than nitrate, indicating the importance of the N-forms deposition for retention in forest ecosystems."],["dc.identifier.doi","10.1007/s11676-009-0054-7"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/5048"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/60223"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.subject.ddc","570"],["dc.title","The fate of 15N-labeled nitrogen inputs to pot cultured beech seedlings"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

The objectives were (i) to evaluate whether these beech forest soils generally exhibit high seasonal N2O emissions and (ii) to assess the influence of gas diffusivity and nitrogen (N) mineralisation on N oxide fluxes. We measured N2O and NOx (NO + NO2) fluxes in six German beech stands and determined net N turnover rates and gas diffusivity of soil samples taken at each chamber. High N2O emissions (up to 113 mu g N m(-2) h(-1)) were only observed at one beech stand. Net nitrification of the organic layer and soil gas diffusivity explained 77 % of the variation in N2O fluxes (P = 0.001). Fluxes of NOx were low (-6.3 to 12.3 mu g N m(-2) h(-1)) and appeared to be controlled by NOx concentrations in the forest air. Low soil gas diffusivity and high N turnover rates promoted high N2O losses in times of high soil respiration but were not necessarily associated with moder type humus. High seasonal emissions are probably less common in German beech forests than previously assumed."],["dc.description.sponsorship","German Research Foundation [BR 1524/6]"],["dc.identifier.doi","10.1007/s11104-013-1602-7"],["dc.identifier.isi","000321642200039"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/10370"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/29262"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Springer"],["dc.relation.issn","0032-079X"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.title","Regulation of N2O and NOx emission patterns in six acid temperate beech forest soils by soil gas diffusivity, N turnover, and atmospheric NOx concentrations"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

However, little is known as to which extent beech leaf litter contributes to N turnover and nitrous oxide (N2O) emissions within one decade after litterfall. In 1997, we exchanged recently fallen leaf litter by N-15-labelled litter in a beech stand (Fagus sylvatica) at the Solling, Germany. Measurements were conducted 2-3 and 10-11 years after litter exchange. Two years after litter exchange, 92 % of added N-15 was recovered in the surface 10 cm of the soil. The labelled N was primarily found in the upper part of the F layer of the moder type humus. Eleven years after litter exchange, 73 % of the added N-15 was lost and the remaining 27 % was mainly recovered in the lower part of the F layer indicating N sequestration. The remaining leaf litter N was subject to measurable N mineralisation (2-3 % of litter N) and N2O production (0.02 %). Between 0.3 % (eleventh year) and 0.6 % (second year) of total annual N2O emissions were attributed to beech leaf litter of a single year.

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"]]
