“…Analysis of soil microbial biomass provides an alternative for examining the impact of plant diversity on soil ecosystem functions regulated by the soil microbial community, such as the cycling of C, N, S and P (O'Donnell et al 2001). Soil microbial biomass drives the turnover of organic matter and the immobilization and mineralization reactions to regulate plant nutrient supply, making it the center of nutrient flux in soil.…”

Relationship between plant species diversity and soil microbial functional diversity along a longitudinal gradient in temperate grasslands of Hulunbeir, Inner Mongolia, China Abstract Numerous experiments have been established to examine the effect of plant diversity on the soil microbial community. However, the relationship between plant diversity and microbial functional diversity along broad spatial gradients at a large scale is still unexplored. In this paper, we examined the relationship of plant species diversity with soil microbial biomass C, microbial catabolic activity, catabolic diversity and catabolic richness along a longitudinal gradient in temperate grasslands of Hulunbeir, Inner Mongolia, China. Preliminary detrended correspondence analysis (DCA) indicated that plant composition showed a significant separation along the axis 1, and axis 1 explained the main portion of variability in the data set. Moreover, DCA-axis 1 was significantly correlated with soil microbial biomass C (r = 0.735, P = 0.001), microbial catabolic activity (average well color development; r = 0.775, P < 0.001) and microbial functional diversity (catabolic diversity: r = 0.791, P < 0.001 and catabolic richness: r = 0.812, P < 0.001), which suggested thatsome relationship existed between plant composition and the soil microbial community along the spatial gradient at a large scale. Soil microbial biomass C, microbial catabolic activity, catabolic diversity and catabolic richness showed a significant, linear increase with greater plant species richness. However, many responses that we observed could be explained by greater aboveground plant biomass associated with higher levels of plant diversity, which suggested that plant diversity impacted the soil microbial community mainly through increases in plant production.

“…ACC deaminase activity was evaluated by measuring of α-ketobutyrate and ammonia production when the ACC is cleavage by ACC deaminase [37,38]. The standard curve were obtained by serial dilutions of α-ketobutyrate at 0, 0.01, 0.05, 0.1, 0.2, 0.5, 0.75 and 1 mM concentrations in 100 mM Tris-HCl pH 8.5 (total Volume 500 μl), mixed in each case with 400 μl of 0.56 N HCl and 150 μl DNF solution (0.1 g 2,4dinitrophenylhydrazine, Sigma, USA; in 100 ml of 2 N HCl) followed by addition of one ml of 2 N NaOH.…”

“…in particular, it aimed to assess the effects of past and current organic and conventional management practices (crop rotation, green manuring, conventional and organic fertilisation) and the result of altering the existing system, i.e., conversion or re-conversion to organic and conventional management, respectively. as microbially mediated soil processes, such as n mineralisation and consequently nitrate leaching, are influenced by inherent soil properties, environmental conditions and anthropogenic activities (O'Donnell et al 2001), it was important to reduce such external differences between the two systems by choosing two sites of the same environmental conditions and the same soil type and then to subject the soils to the same crop rotation.…”

Farming practices can have significant effects on important soil processes, including nitrogen (N) dynamics and nitrate leaching. A lysimeter experiment was conducted to determine differences in N leaching resulting from past and current crop management practices. Intact monolith lysimeters (50cm diam. × 70cm deep) were taken from sites of the same soil type that had either been under long-term organic or conventional crop management. These were then managed according to established organic and conventional practices over 2½ years using the same crop rotation ( manure (Lupinus angustifolius L.)) and two fertiliser regimes, resulting in four treatments based on soil management history and current fertilisation strategy. Dry matter yield of each crop was determined after harvest and leachates were collected after significant rainfall events and analysed for total mineral N concentrations. Mineral fertilisation had a clear positive effect on yields of the first crop, whereas there were no considerable differences between treatments for the last crop owing to a significant positive effect of green manure incorporation on yields. Although there was a trend of lower mineral N leaching from organically fertilised soils (organic management: 24.2 kg N ha -1 ; conventional management: 28.6), differences in N losses were not statistically significant between treatments. This shows that under the experimental conditions, leaching losses and crop yields were more strongly influenced by crop rotation and green manuring than by the presence or absence of mineral fertilisation. Overall, the study highlights the benefits of including a green manure in the crop rotation of any farming system.
