Microbial nitrogen (N) immobilization, which typically results in soil N retention but based on the balance of gross N immobilization over gross N production, affects the fate of the anthropogenic reactive N. However, global patterns and drivers of soil gross immobilization of ammonium (INH4) and nitrate (INO3) are still only tentatively known. Here, we provide a comprehensive analysis considering gross N production rates, soil properties, and climate and their interactions for a deeper understanding of the patterns and drivers of INH4 and INO3. By compiling and analyzing 1966 observations from 274 15N‐labelled studies, we found a global average of INH4 and INO3 of 7.41 ± 0.72 and 2.03 ± 0.30 mg N kg−1 day−1 with a ratio of INO3 to INH4 (INO3:INH4) of 0.79 ± 0.11. Soil INH4 and INO3 increased with increasing soil gross N mineralization (GNM) and nitrification (GN), microbial biomass, organic carbon, and total N and decreasing soil bulk density. Our analysis revealed that GNM and GN were the main stimulators for INH4 and INO3, respectively. The structural equation modeling showed that higher soil microbial biomass, total N, pH, and precipitation stimulate INH4 and INO3 through enhancing GNM and GN. However, higher temperature and soil bulk density suppress INH4 and INO3 by reducing microbial biomass and total N. Soil INH4 varied with terrestrial ecosystems, being greater in grasslands and forests, which have higher rates of GNM, than in croplands. The highest INO3:INH4 was observed in croplands, which had higher rates of GN. The global average of GN to INH4 was 2.86 ± 0.31, manifesting a high potential risk of N loss. We highlight that anthropogenic activities that influence soil properties and gross N production rates likely interact with future climate changes and land uses to affect soil N immobilization and, eventually, the fate of the anthropogenic reactive N.

“…Sources of soil carbon (C) and OM such as crop residues (specifically corn stover in this study) has been widely promoted in agroecosystems all over the world to increase soil C stock, improving synchrony of nutrients supply ( e.g., from mineral fertilization) 44 – 46 . Therefore, keeping crop residues in the field could reduce the amount of N that leaches during the initial stage of crop growth when N demand is low, especially when there is high soil N leaching risk ( e.g., the snow melting or heavy spring rain events during early crop growth stages) 6 , 46 – 49 . The subsequent remineralization of the immobilized N can supply mineral N for crop growth, indicating that the incorporation of corn stover, which contains a larger amount of C with high availability, can improve N synchrony to corn cropping systems by increasing NH 4 + availability.…”

Corn stover is a global resource used in many industrial sectors including bioenergy, fuel, and livestock operations. However, stover removal can negatively impact soil nutrient availability, especially nitrogen (N) and phosphorus (P), biological activity, and soil health. We evaluated the effects of corn stover management combined with N and P fertilization on soil quality, using soil chemical (nitrate, ammonium and Bray-1 P) and biological parameters (β-glucosidase, alkaline phosphatase, arylsulfatase activities and fluorescein diacetate hydrolysis—FDA). The experiment was performed on a Mollisol (Typic Endoaquoll) in a continuous corn system from 2013 to 2015 in Minnesota, USA. The treatments tested included six N rates (0 to 200 kg N ha−1), five P rates (0 to 100 kg P2O5 ha−1), and two residue management strategies (residue removed or incorporated) totalling 60 treatments. Corn stover management significantly impacted soil mineral-N forms and enzyme activity. In general, plots where residue was incorporated were found to have high NH4+ and enzyme activity compared to plots where residue was removed. In contrast, fields where residue was removed showed higher NO3− than plots where residue was incorporated. Residue management had little effect on soil available P. Soil enzyme activity was affected by both nutrient and residue management. In most cases, activity of the enzymes measured in plots where residue was removed frequently showed a positive response to added N and P. In contrast, soil enzyme responses to applied N and P in plots where residue was incorporated were less evident. Soil available nutrients tended to decrease in plots where residue was removed compared with plots where residue was incorporated. In conclusion, stover removal was found to have significant potential to change soil chemical and biological properties and caution should be taken when significant amounts of stover are removed from continuous corn fields. The residue removal could decrease different enzymes related to C-cycle (β-glucosidase) and soil microbial activity (FDA) over continuous cropping seasons, impairing soil health.

“…This could be related to the changes in DOC. Carbon availability can strongly in uence the N immobilization process (Ma et al 2020). Reduced availability of labile carbon leads to a decrease in microbial biomass carbon, thus weakening the microbial N immobilization process (Baldos et al 2015).…”

Biological nitrification inhibitor (BNI) can play an important role in inhibiting nitrification and enhancing nitrogen use efficiency (NUE) in agriculture. However, most of current BNI studies have been conducted under hydroponics. Variations in genotype-mediated inhibition of soil nitrification are still unknown. In this study, two rice genotypes, i.e. Wuyujing 3 (WYJ3) and Wuyunjing 7 (WYJ7), which were reported to have weak and strong BNI capacity under hydroponics, respectively, and four soils with different pH (i.e. JX (pH 5.09), FJ (pH 6.00), SC1 (pH 7.96) and SC2 (pH 7.94)) were selected. N uptake rates (esp. NH4+ uptake, UNH4), soil N transformation rates and NUE were quantified by 15N tracing experiment to assess the effects of rice genotypes on nitrification inhibition activity. Results showed that rice genotypes with high BNI exudation (i.e. WYJ7) had lower autotrophic nitrification rate (ONH4) and higher UNH4 in rhizosphere compared to WYJ3. ONH4 in WYJ7 reduced by 0.05, 0.42, 1.14, and 0.48 mg N kg− 1 d− 1 compared with WYJ3 for JX, FJ, SC1 and SC2, respectively. Abundance of AOB in soils planted WYJ7 was lower than WYJ3, which was the key factor affecting ONH4. NUE of WYJ7 was higher than WYJ3, although difference between genotypes was not significant. NUE was negatively correlated with ONH4 (P < 0.05). Our results indicated that some rice genotypes can optimize their N acquisition by regulating soil N transformations (particularly nitrification). Developing rice genotype with strong BNI exudation capacity could be a suitable management practice to increase NUE and yield.
