“…The higher MBC in soils from the Rc treatment than from the R treatment (Table 1), which reflects the size of the soil microbial community, agrees with findings reported by Saha et al (2008) and Zhao et al (2013), showing that MBC size increased in manure treated soil when compared to soil receiving only inorganic nutrients. It is generally recognized that increased organic residue inputs, either from plants or animal manure, will increase MBC size and enzymatic activities (Buchanan and King 1992;Dick 1992;Stark et al 2008) because of increased availability of C substrate that stimulates microbial activity (Nayak et al 2007).…”

“…This indicates that differences in POC, PON, and DOC80 may be primarily in the free particulate organic C (FPOC) and free particulate organic N d Mean soil quality indicator value ± standard deviation; values followed by different letters for either the three CRM or three N-rate treatments are significantly different at p < 0.05 (FPON) fractions, which is thought to be younger and more plant derived (Six et al 2002a), suggesting the larger POC and PON in the R treatment reflect greater decomposition of recent added crop residues, which occurs through and is catalyzed by soil microorganisms (Saha et al 2008;Stark et al 2008). In addition, the DOC80 includes a portion of MBC and simple organic compounds (Chen et al 2004), suggesting that some simple organic compounds were released from the returned crop residues during the experimental periods.…”

“…Protease activity (PRO) and invertase activity (INV) were measured because PRO characterizes N mineralization (Saha et al 2008), and INV can drive C cycling by catalyzing hydrolysis of sucrose (Frankenberger and Johanson 1983). The PRO was assayed by determining the tyrosine released after incubating the soil with Tris buffer and Na-caseinate at 50°C for 2 h, as indicated by Saha et al (2008).…”

“…The PRO was assayed by determining the tyrosine released after incubating the soil with Tris buffer and Na-caseinate at 50°C for 2 h, as indicated by Saha et al (2008). Results were expressed as mg tyrosine released per kg soil per 2 h (mg tyrosine kg −1 2 h −1 ).…”

“…Soil microorganisms drive decomposition of organic materials (Stark et al 2008), and mineralization of organic matter through a wide range of metabolic processes (Saha et al 2008). These processes depend primarily on the size, activity, and composition of the soil microbial biomass (Böhme et al 2005;Tu et al 2006), suggesting that it is critically important to build diverse soil microbial communities to sustain or improve productivity of the field with crop residues return.…”

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.

Alfalfa-Siberian wild rye intercropping is the predominant cropping system used to produce forage in China. In this study, the effects of intercropping and intercropping-rhizobial inoculation on soil enzyme activities, microbial biomass and bacterial community composition in the rhizosphere were examined. In both treatments, the yield of alfalfa, microbial biomass and activities of soil urease, invertase and alkaline phosphatase in the alfalfa rhizosphere were markedly increased, whereas there was a slight increase in the yield of Siberian wild rye, few impacts on soil microbial biomass, and decreased enzyme activities (except for urease) in the Siberian wild rye rhizosphere. Terminal restriction fragment length polymorphism (T-RFLP) of 16S rRNA genes indicated that Alphaproteobacteria, Betaproteobacteria, Gammaproteobacteria, Deltaproteobacteria, Firmicutes, Actinobacteria and Bacteroidetes were the major bacterial groups in the rhizosphere of both plants. However, intercropping and rhizobial inoculation induced some shifts in the relative abundance of them. Nitrosomonas and Nitrosospira groups were detected in all treatments by the T-RFLP patterns of ammonia monooxygenase subunit A (amoA) gene, but the relative abundance of Nitrosomonas increased and that of Nitrosospira decreased in the intercropping-rhizobial inoculation treatment. Both treatments tended to increase the diversity of amoA. Conclusively, the two treatments clearly affected soil microbial composition and soil enzyme activities, which might be reflected in changes in yield.
