Measuring and modelling of plant effects on denitrification using innovative techniques

使用创新技术测量和建模植物对反硝化的影响

基本信息

项目摘要

The project P7 „Measuring and modelling of plant effects on denitrification using innovative techniques” will use the newly, in DASIM Phase I developed plant-soil-incubation chamber for further characterizing the significance of rhizosphere plant-micro-organism interactions for denitrification and N gas production via denitrification (NO, N2O, N2) in soils. In addition to the so far used Helium (He) gas flow technique, which is based on the headspace gas exchange with a N2 free atmosphere mixture of He and O2 to allow for N2 production, we will for the first time test the suitability of advanced Raman spectroscopy for N2 production measurements under “standard” atmospheric composition conditions (ca. 20% O2/ 80% N2). Though this will require further developments of the photonic technology, we are very positive that this new technological approach will offer new insights and a scientific breakthrough in our capability to measure soil-plant denitrification dynamics in soils directly.We hypothesize that plant photosynthesis and rhizosphere denitrification are closely coupled via root exudation, with relationships not being quantified yet. Laboratory and field-lysimeter experiments (total N balance of large intact soil cores under field condition) will be executed in close cooperation with all DASIM partners. Results of own experiments as well as experimental and modelling results of DASIM partners will be used for the further development of the denitrification and soil hydrology/physics submodules of the biogeochemical model LandscapeDNDC. This model will be used for testing various currently developed DASIM model approaches and for scaling resul
项目P7“使用创新技术测量和建模植物对反硝化作用的影响”将使用DASIM第一阶段新开发的植物-土壤培养室,进一步表征根际植物-微生物相互作用对反硝化作用和N气体产生的重要性通过反硝化作用(NO、N2 O、N2)在土壤中。除了迄今为止使用的氦气(He)气流技术,该技术基于与He和O2的无N2气氛混合物的顶空气体交换以允许N2产生,我们将首次测试先进的拉曼光谱在“标准”大气成分条件下(约100 ℃)用于N2产生测量的适用性。20%O2/80%N2)。虽然这需要光子技术的进一步发展,但我们非常肯定,这种新的技术方法将为我们直接测量土壤-植物反硝化动力学的能力提供新的见解和科学突破。我们假设植物光合作用和根际反硝化作用通过根系分泌物密切耦合,关系尚未量化。将与DASIM的所有合作伙伴密切合作,进行实验室和实地蒸渗仪实验(在实地条件下大型完整土芯的总氮平衡)。自己的实验结果以及DASIM合作伙伴的实验和建模结果将用于进一步开发生物地球化学模型LandscapeDNDC的反硝化和土壤水文/物理子模块。该模型将用于测试各种目前开发的DASIM模型方法和缩放结果,
