“…The high C/N in maize stover with a high N level (N300) increased mineralization of LOC, so LOC first increased and then decreased (Tang et al 2020). SR without tillage can improve LOC content (Yang et al 2020b), and a significant positive correlation between N application and LOC has been observed (Huang et al 2014). Tillage practices that influence LOC content and SR improve LOC content, soil nutrient use efficiency and increase ecosystem carbon input (Chen et al 2009).…”

“…However, the long-term application of N fertilizer alone or excess N application will increase soil microbial activity in the short term, thus reducing soil MBC content. Nitrogen input can rapidly stimulate soil microbial activity, improve carbon sequestration in microbial biomass and increase MBC content within a short period (Joergensen & Scheu, 1999;Huang et al 2014). SR combined with an appropriate amount of N can adjust the soil C/N ratio and increase MBC within a particular N range (Murugan et al 2019).…”

Cultivation techniques have an important influence on grain yield of maize. This experiment investigated the effect of stover return (SR) and different nitrogen (N) application rate on soil organic carbon (SOC) composition, soil nutrient and maize yield.• Different nitrogen application rate 100 (N100), 150 (N150), 200 (N200), 250 (N250) or 300 (N300) kg ha À1 applied to the maize field with stover return and without stover return traditional planting (TP) method.• Nitrogen application rate and stover return affected the SOC, labile organic carbon (LOC), microbial biomass (MBC), NO 3 À -N, NH 4 + -N and maize yield. Soil N, soil carbon content and maize yield of SR were all higher than TP. The SOC content of SR and TP were 9.67 and 9.19 g kg À1 , respectively. Nitrogen application was significantly and positively correlated with soil MBC, LOC, SOC, NO 3 À -N, NH 4 + -N and yield. The maximum values of SOC composition, soil nutrients and maize yield were reached at SR with 250 kg ha À1 .• Stover return with application of N 250 kg ha À1 significantly increased the growth attribute and maize yield in subtropical region compared with traditional planting.

“…Changes in DOC contents may potentially cause fluctuations in the magnitude of CO 2 emissions (Davidson et al 2000). As a specific fraction of organic C, dissolved organic carbon (DOC) represents an easily degradable and available substrate to microorganisms (Boyer and Groffman 1996;Huang et al 2014). Soil respiration has been revealed to be reliant on C supply (Silva et al 2009;Sevilla-Perea et al 2015).…”

Information on soil N 2 O and CO 2 emissions from above-and below-ground biomass of legume crops is limited in scientific literature. Therefore, a laboratory study was conducted to evaluate the differences in soil N 2 O and CO 2 emissions from the above-and below-ground biomass of green bean. Leave and shoot (LS) and root nodule (Nod) of green bean were incorporated into soil and incubated for 53 days. N 2 O and CO 2 emissions were measured throughout the 53-day study period. Incorporation of organic residues significantly (p B 0.05) increased N 2 O and CO 2 emissions. However, the Nod treatment yielded higher emissions of N 2 O as compared to LS treatment. Cumulative N 2 O emissions were 13-fold and fourfold in Nod and LS treatment as compared to the control, respectively. CO 2 emissions were higher in LS treatment than that of Nod treatment. Cumulative CO 2 emissions were 2.15-fold and 1.15-fold in LS and Nod treatments as compared to the control, respectively. The results of current study suggest that below-ground biomass of legume crops produces higher N 2 O emissions while CO 2 emissions were higher in above-ground biomass.

“…However, the response of C and N fractions and their transformations to the application of organic amendments and CFs is still intensively debated. Some studies showed a positive effect of combining organic and inorganic sources of nutrients on increasing soil C and N fractions (Mi et al ., ; Chaudhary et al ., ), whereas others have shown that the combination had no effect (Rudrappa et al ., ; Huang et al ., ). These disparities may result from variations in soil type, cropping system and the quality of the organic pool (Ding et al ., ).…”

We investigated the effects of compost (CM), made from poultry and cattle manure with spent mushroom substrate, plus chemical fertilizers (CFs) on soil organic carbon (C) and nitrogen (N) fractions in silty loam soil of the Loess Plateau. Eight fertilizer practices were applied in a 7‐year‐old ‘Red Fuji’ apple (Malus domestica Borkh.) orchard for 360 days. Compared to CM alone, CM–CFs decreased slightly soil total organic C but increased total N by 4.3–11.6%. Notably, CM–CFs increased soil microbial biomass C (MBC) by 2.7–26.5% and microbial biomass N (MBN) by 7–13.7%. Soil water‐soluble carbon (WSC) was increased by 20.7% and 19.2% when 2% CM plus N and phosphorus (P) (2%M–NP) and 4% CM plus N and P (4%M–NP) were applied, respectively. Whereas 0.5% CM plus N and P (0.5%M–NP) increased WSC by 9.3% on day 30 but decreased it by 7.2% from 30–360 days. Hot water‐soluble C increased by 13.1–14.6% from 0–180 day, but thereafter, the effect disappeared. Compared to CFs, CM–CFs increased MBN by 35.1–115.6%, and increased alkali‐hydrolyzable‐N by 3.5–55.8% over 180–360 days of incubation. Additionally, CM–CFs promoted N mineralization, increasing NH4‐N and NO3‐N contents. Based on the changes in C and N fractions and available nutrients, 2%M–NP (45 t/ha of CM plus 450 kg/ha of N and 157.5 kg/ha of P) may be the optimal fertilizer strategy for stimulating soil microbial growth and activity, and enhancing nutrient cycling for apple growth.
