1. N and P inputs can alter the structure of soil bacterial communities in semi-arid steppes.
2. N inputs primarily affect bacterial communities by changing the pH, while P inputs do so mainly by improving P availability.
3. Higher N and P input levels lead to more severe niche differentiation in the bacterial community.
The article is generally reliable and trustworthy, as it provides a detailed analysis of how long-term nitrogen (N) and phosphorus (P) inputs can affect soil bacterial communities in semi-arid steppes. The authors use high-throughput Illumina Miseq sequencing to characterize the bacterial communities, and their results show that both N and P additions altered the bacterial community structure. They also found that higher N or P input levels led to more severe niche differentiation in the bacterial community, with N inputs primarily affecting the community by changing the pH, while P inputs did so mainly by improving P availability.
The article does not appear to have any major biases or one-sided reporting, as it presents both sides of the argument equally and objectively. It also does not contain any unsupported claims or missing points of consideration; instead, it provides a comprehensive overview of how long-term N and P inputs can affect soil microbial communities in semi-arid steppes. Furthermore, there is no promotional content or partiality present in the article; instead, it provides an unbiased analysis of its findings. Finally, possible risks are noted throughout the article; for example, it mentions that nutrient additions may limit plant production in steppes and affect plant community structure.
In conclusion, this article is reliable and trustworthy due to its comprehensive analysis of how long-term N and P inputs can affect soil microbial communities in semi-arid steppes.
