Chemical analysis of nitrogen transformations in biochar amended soil

These data are from an investigation of the effects of biochar application to soil, on soil greenhouse gas emissions and N transformations within the soil. Biochar is a carbon rich substance which is being advocated as a climate mitigation tool to increase carbon sequestration and reduce nitrous oxide emissions. The data were collected during a 15N pool dilution incubation to investigate the nitrogen transformations within biochar-amended soil following the addition of 15N-labelled ammonium nitrate. Analyses included 15N content of nitrous oxide and 15N content of soil. The N transformations were then modelled using a model for calculating nitrogen fluxes in soil using 15N tracing (FLUAZ model).

本研究数据源自对生物炭施用于土壤后土壤温室气体排放及土壤中氮素转化的影响进行的调查。生物炭是一种富含碳的物质，被推崇为一种气候减缓工具，旨在提高碳汇能力和降低氧化亚氮排放。数据收集于15N池稀释培养过程中，以研究在添加15N标记的硝酸铵后生物炭改良土壤中的氮素转化。分析包括氧化亚氮的15N含量和土壤的15N含量。随后，利用基于15N示踪计算土壤氮通量的FLUAZ模型对氮素转化进行了建模。关于该数据集的详细信息可查阅https://doi.org/10.5285/69d89261-b7ee-4b56-bb13-1128e3c8dd93。
