Subproject P7 investigates the molecular and isotopic composition of lipids in soils of different management systems, of different crop plants and of the corresponding substrates on which the soils evolved. Lipids chemotaxonomically differentiate the plant input into soil, identify plant combustion residues (PAH) that contribute to soil organic matter, and identify the microbial communities that thrive in soils of variable developmental stage. As the biogeochemistry of paddy soils depends on all of these control factors, lipid compositions are highly complementary to other approaches utilized in this project. The Fluvisol substrate composition in the coastal Cixi area and its lipid biogeochemistry has been characterized in detail in the first phase of FOR995. Extension and validation of these results via the study of different substrate types and associated effect on soil lipids will be conducted on Acrisols from China and Andosols, Vertisols and Acrisols/Ferralsols from Indonesia. Establishment of adapted microbial communities after conversion of marine tidal flats to paddy soils commenced in less than 50 years and thereafter remained rather stable for up to 2000 years in the Cixi area. An accelerated adaption to paddy management is hypothesized for the tropical environment in Indonesia, where a chronosequence with 110, 45 and 3 years of paddy use will be used to verify the postulated rapid changes in soil lipids. The management practices in Indonesia are expected to enforce longer periods of anoxia in paddies, affecting microbial activity and soil organic matter preservation. Environmental differences in paddy soil lipid geochemistry for the Cixi and Red Earth area in China, as well as for Java and Sumatera will be synthesized to obtain a general perspective of paddy soil evolution in Southeast Asia.

P7子项目调查了不同管理系统、不同作物和相应土壤基质中脂类的分子和同位素组成。脂类从化学分类上区分植物进入土壤的输入，确定对土壤有机质有贡献的植物燃烧残留物(PAH)，并确定在不同发育阶段的土壤中茁壮成长的微生物群落。由于水稻土的生物地球化学依赖于所有这些控制因素，因此脂肪成分与本项目中使用的其他方法具有很强的互补性。在FOR995的第一阶段中，对慈溪沿海地区的Flvisol底物组成及其脂质生物地球化学进行了详细的表征。通过对不同底物类型及其对土壤脂的相关影响的研究，将在中国和印度尼西亚的安多索、变性土和阿克苏/铁铝土上对这些结果进行推广和验证。在慈溪地区，在海洋滩涂转化为水稻土后，适应微生物群落的建立在不到50年的时间里就开始了，此后在长达2000年的时间里保持相当稳定。印度尼西亚的热带环境假设加速适应稻田管理，将使用110年、45年和3年的稻谷使用时间序列来验证假设的土壤脂肪的快速变化。印度尼西亚的管理措施预计会延长稻田的缺氧期，影响微生物活动和土壤有机质的保存。将综合中国慈溪和红壤地区以及爪哇和苏门答腊岛水稻土脂肪地球化学的环境差异，以获得东南亚水稻土演化的总体前景。
