TL;DR: The data implicate the role of livestock manures in preventing the loss of bacterial diversity during long-term chemical fertilization, and highlight pH as the major deterministic factor for soil bacterial community structure.

TL;DR: Under the application of chemical fertilizers, the addition of livestock manures had much stronger effects on the abundance of nitrogen cycle genes than the added of wheat straw, and bacterial and archaeal amoA genes were more sensitive to fertilization than other functional genes.

TL;DR: It is found that N fixation was drastically reduced after almost four decades of fertilization, and functionality losses were associated with reductions in the relative abundance of keystone and phylogenetically clustered N fixers such as Geobacter spp.

TL;DR: The results indicate that organic matter addition influences the composition and structure of soil fungal communities in predictable ways.

TL;DR: This work uses multitrophic ecological networks to investigate the importance of soil biodiversity, in particular, the biodiversity of key-stone taxa in controlling soil functioning and wheat production in a 35-year field fertilization experiment, and provides a list ofKey-stone phylotypes linking to crop production and soil nutrient cycling, which could give science-based guidance for sustainable food production.
