“…For instance, in a semiarid steppe, bacterial diversity was negatively correlated with N application rate (Ling et al., ). In contrast, in rice‐wheat cropping systems, N fertilization either significantly increased or had no influence on bacterial diversity (Gu, Zhang, Tu, & Lindström, ; Tian et al., ). Our meta‐analysis agreed with those studies showing that under N fertilization alone, soils with relatively aerobic condition favor lower bacterial diversity while relatively anaerobic conditions favor higher bacterial diversity (Figure a,c).…”

Long-term elevated nitrogen (N) input from anthropogenic sources may cause soil acidification and decrease crop yield, yet the response of the belowground microbial community to long-term N input alone or in combination with phosphorus (P) and potassium (K) is poorly understood. We explored the effect of long-term N and NPK fertilization on soil bacterial diversity and community composition using meta-analysis of a global dataset. Nitrogen fertilization decreased soil pH, and increased soil organic carbon (C) and available N contents. Bacterial taxonomic diversity was decreased by N fertilization alone, but was increased by NPK fertilization. The effect of N fertilization on bacterial diversity varied with soil texture and water management, but was independent of crop type or N application rate. Changes in bacterial diversity were positively related to both soil pH and organic C content under N fertilization alone, but only to soil organic C under NPK fertilization. Microbial biomass C decreased with decreasing bacterial diversity under long-term N fertilization. Nitrogen fertilization increased the relative abundance of Proteobacteria and Actinobacteria, but reduced the abundance of Acidobacteria, consistent with the general life history strategy theory for bacteria. The positive correlation between N application rate and the relative abundance of Actinobacteria indicates that increased N availability favored the growth of Actinobacteria. This first global analysis of long-term N and NPK fertilization that differentially affects bacterial diversity and community composition provides a reference for nutrient management strategies for maintaining belowground microbial diversity in agro-ecosystems worldwide.

“…Compost application can improve the physical structure, fertility of soil and microbial activity (Tian et al, 2015) that have a positive impact on carrot biomass. Also, residual effect of compost induced higher biomass of jew's mallow plants which might be due to slow release of nutrients from compost which are available to plants.…”

“…To be specific, N fertilization can potentially change the quantity and quality of substrate inputs [3, 10, 11], alter soil micro-environment, and further influence the composition and biological activity of soil microbial communities [12–15]. All these changes induced by N fertilization can in turn potentially affect the performance of soil respiration and its sensitivity to temperature changes.…”

Nitrogen (N) fertilization has a considerable effect on food production and carbon cycling in agro-ecosystems. However, the impacts of N fertilization rates on the temperature sensitivity of soil respiration (Q10) were controversial. Five N rates (N0, N45, N90, N135, and N180) were applied to a continuous winter wheat (Triticum aestivum L.) crop on the semi-arid Loess Plateau, and the in situ soil respiration was monitored during five consecutive years from 2008 to 2013. During the growing season, the mean soil respiration rates increased with increasing N fertilization rates, peaking at 1.53 μmol m−2s−1 in the N135 treatment. A similar dynamic pattern was observed during the non-growing season, yet on average with 7.3% greater soil respiration rates than the growing season. In general for all the N fertilization treatments, the mean Q10 value during the non-growing season was significantly greater than that during the growing season. As N fertilization rates increased, the Q10 values did not change significantly in the growing season but significantly decreased in the non-growing season. Overall, N fertilization markedly influenced soil respirations and Q10 values, in particular posing distinct effects on the Q10 values between the growing and non-growing seasons.
