“Soil organisms create a living, dynamic system that needs to be understood and managed properly for best plant growth.
Understanding soil health requires knowing what organisms occur, which ones are working, how many are present and whether they are the right kinds for the desired plants.”

Description:
The survey presented here describes the bacterial diversity and community structures of a pristine forest soil and an anthropogenic terra preta from the Western Amazon forest using molecular methods to identify the predominant phylogenetic groups.
Bacterial community similarities and species diversity in the two soils were compared using oligonucleotide fingerprint grouping of 16S rRNA gene sequences for 1500 clones (OFRG) and by DNA sequencing.
The results showed that both soils had similar bacterial community compositions over a range of phylogenetic distances, among which Acidobacteria were predominant, but that terra preta supported approximately 25% greater species richness.
The survey provides the first detailed analysis of the composition and structure of bacterial communities from terra preta anthrosols using noncultured-based molecular methods.
