“…This intriguing finding partly differs from previous studies in relation to microbial community succession during straw decomposition. For instance, Cahyani et al (2002) found that the succession of microbiota during the composting process of rice straw was primarily influenced by the changes in organic constituents, not just DOC or water-soluble organic matter. Bastian et al (2009) reported that the dynamics of community structure seemed to be related to straw-derived CO 2 and soluble C. By manipulating soil transplantation experiment, Sun et al (2013) observed that geographic location rather than soil inherent properties was the primary determinant for microbial communities associated with straw decomposition.…”

It is of ecological significance to investigate microbial communities in response to straw amendment and moisture in arable soils. However, in Chinese fluvo-aquic soils, these responses are still poorly understood. We designed an incubation experiment involving two soils with and without the addition of maize stubble at two moisture levels, and bacterial community structure at days 20, 80, and 200 after the start of incubation was assessed via bar-coded pyrosequencing of the 16S rDNA amplicons. In the presence of stubble with identical moisture level, we observed higher bacterial diversity and richness in long-term organic manure-fertilized soil compared with the unfertilized soil at days 20 and 80, which we attributed to the different quality and quantity of organic matter between the two soils. However, there was no significant difference in bacterial diversity and richness between the two soils at day 200, indicating that long-term straw amendment probably lessens the difference in bacterial community structure between the two soils. In the amended soils bacterial diversity, richness, and community composition at 25% of the water-holding capacity distinctly differed from those at 55% of the waterholding capacity, indicating that moisture strongly affects bacterial distribution in the amended soils. As stubble-C availability declined over time, the dominance of copiotrophic population weakened, and oligotrophic population was moderately abundant. Finally, our study suggests that dissolved organic carbon, which drives redistribution in copiotrophic and oligotrophic categories in response to the varying water and stubble-C availability, is a determinant of bacterial community composition in the amended soils.

“…Rice straw compost at the curing stage on May 24, 2002 (about 5 months after the onset of composting) was sampled from the compo sting pile at the same Center. The composting process of rice straw was described previously (Cahyani et al 2002). The rice straw compost samples (about 80 g wet weight each) were cut into 1 cm segments and interleaved between glass fiber sheets (Whatman GF / 0, diameter 15 cm, pore size 2.7 /Lm), based on a modification of the method of Maeda and Onikura (1977).…”

However, microbial communities of rice straw compost responsible for the decomposition of compost in paddy field soil have not yet been elucidated.…”

“…In the present study, we buried rice straw compost, which was collected from the same composting yard as that used in the previous study by Cahyani et al (2002), in a Japanese paddy field at the time of transplanting of rice plants. The PLFA composition of microbiota in the rice straw compost was determined by sampling the compost throughout the duration of the placement.…”

“…We described here the microbial communities responsible for the decomposition of rice straw compost incorporated into a Japanese paddy field under flooded conditions during the cultivation period of paddy rice. We applied PLFA analysis to determine the community structure by comparing the results with those for rice straw decomposition in soil (Nakamura et al 2003) and for the composting process of rice straw (Cahyani et al 2002).…”

During composting, the composition of microbial communities is subject to constant change owing to interactions with fluctuating physicochemical parameters. This study explored the changes in bacterial and fungal communities during cattle farm waste composting and aimed to identify and prioritize the contributing physicochemical factors. Microbial community compositions were determined by high‐throughput sequencing. While the predominant phyla in the bacterial and fungal communities were largely consistent during the composting, differences in relative abundances were observed. Bacterial and fungal community diversity and relative abundance varied significantly, and inversely, over time. Relationships between physicochemical factors and microbial community compositions were evaluated by redundancy analysis. The variation in bacterial community composition was significantly related to water‐soluble organic carbon (WSOC), and pile temperature and moisture (p < .05), while the largest portions of variation in fungal community composition were explained by pile temperature, WSOC, and C/N (p < .05). These findings indicated that those parameters are the most likely ones to influence, or be influenced by the bacterial and fungal communities. Variation partitioning analyses indicated that WSOC and pile temperature had predominant effects on bacterial and fungal community composition, respectively. Our findings will be useful for improving the quality of cattle farm waste composts.
