Abstract Measuring the nitrogen isotope compositions (δ 15 N) of nitric oxide (NO) from different sources helps to quantify relative contributions atmospheric NO x . Soil is one most important , but only limited measurements on δ N soil‐emitted exist, hampering our ability partition air pollution. Here we conducted soil incubations measure N‐NO under defined aerobic or anaerobic conditions, favoring either nitrification denitrification. Soils were collected seven sites spanning three...
Abstract Human activities have released a large amount of nitric oxides (NOx) into the atmosphere, leading to elevated regional atmospheric NOx concentration and nitrogen (N) deposition. Several studies observed downward or NOy (NOx its oxidation products) flux forest canopy, but attributed it photochemical reactions conversion from gaseous N particulate N. Here, we focus on possibility sink by canopy based an 0.28 kg ha −1 yr in temperate northeastern China, using hourly monitoring fluxes....
Rainfed agriculture is one of the most common farming practices in world and vulnerable to global climate change. However, only limited studies have been conducted on rainfed agriculture, mainly using low-frequency manual techniques, which caused large uncertainties estimating annual N 2 O emissions. In this study, we used a fully automated system continuously measure soil emissions for two years (April 2017 March 2019) typical maize field Northeast China. The were 2.8 kg ha −1 year 1 2018)...
