“…1), suggesting that soil microorganisms may not be sensitive to the three fertilizer rates used in this study. This is consistent with many previous reports conducted on forest soils (Lucas et al 2007), bentgrass soils (Liu et al 2011), and farmland soils (Chu et al 2007). Inorganic N did not show any significant influence on abundance of soil microbes, nor on their composition measured by lipid analysis (Lucas et al 2007).…”

“…Inorganic N did not show any significant influence on abundance of soil microbes, nor on their composition measured by lipid analysis (Lucas et al 2007). Using denaturing gradient gel electrophoresis (DGGE), Liu et al (2011) found that the differences in microbial community composition occurred only between unfertilized and fertilized plots rather than between fertilizer rates after 1-year fertilization treatments, while Chu et al (2007) reported that DGGE banding pattern was not altered regardless of soil was fertilized or not following 16-year fertilization treatments.…”

Xiying, "Crop residue management and fertilization effects on soil organic matter and associated biological properties" (2016 Abstract Returning crop residue may result in nutrient reduction in soil in the first few years. A two-year field experiment was conducted to assess whether this negative effect is alleviated by improved crop residue management (CRM). Nine treatments (3 CRM and 3 N fertilizer rates) were used. The CRM treatments were (1) R0: 100 % of the N using mineral fertilizer with no crop residues return; (2) R: crop residue plus mineral fertilizer as for the R0; and (3) Rc: crop residue plus 83 % of the N using mineral and 17 % manure fertilizer. Each CRM received N fertilizer rates at 270, 360, and 450 kg N ha −1 year −1 . At the end of the experiment, soil NO 3 -N was reduced by 33 % from the R relative to the R0 treatment, while the Rc treatment resulted in a 21 to 44 % increase in occluded particulate organic C and N, and 80°C extracted dissolved organic N, 19 to 32 % increase in microbial biomass C and protease activity, and higher monounsaturated phospholipid fatty acid (PLFA):saturated PLFA ratio from stimulating growth of indigenous bacteria when compared with the R treatment. Principal component analysis showed that the Biolog and PLFA profiles in the three CRM treatments were different from each other. Overall, these properties were not influenced by the used N fertilizer rates. Our results indicated that application of 17 % of the total N using manure in a field with crop residues return was effective for improving potential plant N availability and labile soil organic matter, primarily due to a shift in the dominant microorganisms.

“…On the other hand, soil pH is an important factor regulating microbial properties. Generally, soil acidification after N addition could reduce soil microbial biomass and activity (Liu et al 2011). A recent meta-analysis using 82 field studies after N addition concluded that microbial biomass declined 15 % on average Table 2 are cited from Zhao et al (2010) under N fertilization, and these declines in microbial biomass were more evident in studies of longer duration and with higher total amounts of N addition (Treseder 2008).…”

Abstract• The key message N addition decreased soil inorganic P availability, microbial biomass P, and acid phosphatase activity in the larch plantation. Soil inorganic P availability decreased after N addition due to the changes in both microbial properties and plant uptake.• Context Soil phosphorus (P) availability is considered an important factor in influencing the biomass production of plants. Sustained inputs of nitrogen (N) through atmospheric deposition or N fertilizers, particularly in temperate forests, may change the composition and availability of P and thus affect long-term forest productivity.• Aims The objective of this study was to assess soil P availability, P fractions, and microbial properties including microbial biomass P and acid phosphatase activity after 9 consecutive years of N addition in a larch (Larix gmelinii) plantation, northeastern China.• Methods From 2003 to 2011, NH 4 NO 3 was added to replicate plots (three 20 m×30 m plots) in the larch plantation each year at a rate of 100 kg N ha. Soil samples from 0-10-cm and 10-20-cm depths were collected in N addition plots and control (no N addition) plots.• Results N addition significantly decreased soil NaHCO 3 -Pi (Pi is inorganic P), microbial biomass P, and acid phosphatase activity but increased the NaOH-Pi concentration. N addition appeared to induce a decrease in soil inorganic P availability by changing pH and P uptake by trees. In addition, N addition significantly decreased the NaOH-Po (Po is organic P) concentration, possibly because of increased P mineralization. However, the total P and other P fractions were unaffected by N fertilization.• Conclusion Our results suggested that N addition enhanced P uptake by trees, whereas it reduced soil inorganic P availability as well as microbial biomass and activity related to soil P cycling in the larch plantation.Keywords Larch plantation .

“…The spatial pattern of microbial metabolic activity could be related to soil water availability (Marschner and Kalbitz 2003), nutrient availability (Wang et al 2011 activity is limited more by water than C or N in forests (Li et al 2004;Chaer et al 2009), and the higher soil microbial activity in the temperate forests relative to those of the boreal and subtropical forests might be associated with microbes that are resistant to drought stress (Papatheodorou et al 2004). Additionally, N availability strongly regulates soil microbial activities and processes in the forests of the East Asian monsoon climate region (Liu et al 2011;Wang et al 2011). In N-poor temperate and boreal forest soils, more photoassimilates are allocated below ground to support microbial processes.…”

Soil microbial communities play an essential role in soil carbon (C) emission and C sequestration in forest ecosystems. However, little information is available regarding the relationship between soil C dynamics and microbial substrate utilization at large scales. Along the North-South Transect of Eastern China (NSTEC), seven forests representative of boreal, temperate and tropical biomes were examined. Soil heterotrophic respiration (R h ), soil dissolved organic C (DOC), microbial biomass C (MBC), and microbial community-level physiological profiles (CLPPs) were investigated using biochemical measurements, static chamber-gas chromatography analysis, and Biolog-Eco microplates, respectively. We found that soil R h rates were significantly higher in subtropical and boreal forests than in temperate forests. Conversely, the concentrations of soil DOC and MBC, as well as microbial metabolic activity and functional diversity, were consistently higher in temperate forests than in subtropical forests. There were considerably different substrate utilization profiles among the boreal, temperate, and subtropical forests. Soil microorganisms from the temperate and boreal forests mainly metabolized high-energy substrates, while those from the subtropical forests used all substrates equally. In addition, soil R h rates were significantly and negatively related to soil labile C concentrations, total metabolic activity, and the intensity of individual substrate utilization, indicating that soil microbes assimilated more soil substrates, thereby reducing CO 2 emissions. Overall, our study suggests that climate fac-tors, as well as substrate availability, dominate the activities and functions of soil microbes at large scales.
