Drainage class and soil phosphorus availability shape microbial communities in Irish grasslands

Soil drainage and phosphorus (P) availability are considered indicators of management intensity in pasture-based agriculture supporting livestock. However, microbial adaptations to P-availability according soil class rarely investigated. We hypothesized that well-drained grasslands with high will sustain a distinctive microbiota when compared poorly-drained low-P availability. The relationship between drainage, plant available P grassland communities was evaluated among sites high- or low-P, using fingerprinting, next-generation sequencing quantitative PCR. Bacterial community structures were primarily affected by as well significantly separated combination i.e. poorly drained versus high-P drained.
