Resolving broad patterns of prokaryotic community structure in New Zealand pasture soils
Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
The importance of pasture soils to the New Zealand economy and global food security cannot be understated. Additionally, the importance of soil biodiversity to soil ecosystem functioning and, consequently, food production is becoming apparent. Despite this, our understanding of soil biodiversity is still developing. Here, we review the literature on soil microbial communities inhabiting pasture soils across New Zealand in order to summarise the key properties that impact microbial distributions. This work also includes an examination of 16S rRNA sequencing data from 92 pasture sites. The goal of this examination is to re-test the properties identified in the review on a prokaryote-focused dataset generated by contemporary techniques. Results from this work indicate that pH strongly influences soil microbial communities on a landscape scale, and that this conclusion can be drawn using a range of experimental methods. Geographic region, land use and soil classification serve as secondary modifiers, indicating that these factors may interact resulting in the broad impact of pH.
