SFB 552: B5 - Effects of ENSO droughts and land-use practices on soil C, N, P dynamics in a tropical rainforest and agroforestry systems in Central Sulawesi, Indonesia
Project
Project code: DFG SFB 552
Contract period: 01.01.2006
- 01.01.2011
Purpose of research: Basic research
The project aims to characterize the response of soil nutrient (N, P) and soil carbon storage and dynamics to experimental drought and land-use practices in Central Sulawesi, Indonesia. In a throughfall exclusion experiment the impacts of a moderate and a severe drought and subsequent re-wetting cycles in a natural tropical forest and in a cacao agroforest will be analysed with regard to soil organic matter (SOM) decomposition and N, P and C turnover and availability. Responses of nutrient availability to different land-use management practices such as N-fertilisation and weeding activities are studied in cacao agroforestry systems. By this project we hope to improve our knowledge about relevant processes for nutrient dynamics and the preservation of forest and agricultural ecosystem functions and services.
