“…2a, b) indicating that autotrophic nitrification occurred. C 2 H 2 was assumed to totally inhibit autotrophic nitrification based on the used concentration (Lu and Jia 2013;Zhang et al 2014); therefore, any NO 3 − produced was considered to have resulted from heterotrophic nitrification. Sahrawat et al (1987) found that C 2 H 2 was a very effective nitrification inhibitor in organic and mineral soils and only blocked autotrophic nitrification (Killham 1987;Zhang et al 2013b).…”

“…1), and many studies have proposed that heterotrophic nitrifiers can use both inorganic and organic substrates (De Boer and Kowalchuk 2001;Zhang et al 2014). Recently, nitrification inhibitors and 15 N isotope technique have been used widely to distinguish autotrophic and heterotrophic nitrification (Pedersen et al 1999).…”

“…In contrast to the other studies of acid forest soils, Zhang et al (2013b) showed that heterotrophic nitrification was the predominant NO 3 − pathway in an acid coniferous forest soil (pH 4.5) in subtropical China. Zhang et al (2014) revealed that the contribution of heterotrophic nitrification to total nitrification was 93 % when maize straw was used as a N substrate in acidic forest soil (pH 4.7). Therefore, it is necessary to determine the relative roles of heterotrophic and autotrophic nitrification in different soils to develop models for nitrification to provide information to guide soil management to improve N use efficiency.…”

A laboratory incubation experiment was conducted using the nitrification inhibitor acetylene and 15 N isotope techniques in order to determine the relative significance of heterotrophic and autotrophic nitrification in three acid soils from different locations in Australia. The contribution of heterotrophic nitrification to total nitrification was found to vary from 20-88 % amongst the three soils. In the less acidic Glenormiston soil (pH w 6.2, organic C content 5.6 %), nitrification was largely autotrophic with heterotrophic nitrification accounting for only 20 %. However, in the more acidic and higher organic C content Longworry soil (pH w 4.8 and organic C content 9.3 %), heterotrophic nitrification was the predominant NO 3 − production pathway accounting for 88 % of total nitrification.

“…The activities of nitrifying microorganisms can be restricted by the availability of a limited range of substrates and is a significant feature controlling heterotrophic nitrification (Zhang et al, 2014). Unexpectedly, the pH had no effect on the rates of nitrification.…”

“…The addition of substrates in different treatments can cause noteworthy changes in the soil pH. For example, Zhang et al (2014) reported significant changes in the pH of soil after the addition of substrates. Low concentrations of ammonium may curtail the growth of AOA or cause the N concentration of ecosystems to be low (Könneke et al, 2005).…”

Manure application is effective in promoting soil carbon sequestration, but its impact on N2O emission is not well understood. A field experiment was conducted in a maize‐cultivated black soil in Northeast China with six treatments: inorganic fertilizer (NPK), 75% inorganic fertilizer N plus 25% pig (PM1) or chicken (CM1) manure N, 50% inorganic fertilizer N plus 50% pig (PM2) or chicken (CM2) manure N, and no N fertilizer (CK). Annual N2O emission significantly increased from 0.34 kg N ha−1 for CK to 0.86 kg N ha−1 for NPK and further to 1.65, 1.02, 1.17, and 0.93 kg N ha−1 for PM1, CM1, PM2, and CM2, respectively. A 15N tracing study showed that 71–79% of total N2O was related to nitrification at 30–70% water‐filled pore space (WFPS), and heterotrophic nitrification contributed 49% and 25% to total N2O at 30% and 70% WFPS, respectively. In an incubation, N2O emission was only stimulated when nitrate and glucose were applied together at 60% WFPS, indicating that denitrification was carbon limited. PM had a stronger effect on denitrification than CM due to higher decomposability, and the lower N2O emission at higher manure application rate was associated with decreased mineral N supply. After compiling a worldwide database and establishing an empirical model that related N2O emissions (kg N ha−1) to precipitation (Pr, m) and fertilizer N application rate (Nr, kg N ha−1) (N2O = 1.533Pr + 0.0238PrNr), annual N2O emission from global‐cultivated black soil applied with inorganic fertilizer N was estimated as 347 Gg N. Our results suggested that N2O emission from cultivated black soils in China was low primarily due to low precipitation and labile organic carbon availability, and would be stimulated by manure application; thus, increased N2O emission should be taken into consideration as applying manure increases soil organic carbon sequestration.
