Data for: Differential structure and function of phosphorus-cycling microbial communities in organic and upper mineral soil horizons across a temperate rainforest chronosequence

Field campaign sampling dunes along the Big Bay chronosequence, on the west coast of New Zealand’s South Island at the mouth of the Awarua River (44.2988°S, 168.0672°E) in November 2018.  Dunes with approximate ages of 300, 800 and 4000 yBP (i.e., corresponding to earthquake events in the years 1717, 1220 and ~4000 years ago; also referred as BBX1717, BBX1220 and BBX04) were chosen for detailed soil sampling.  We paired analysis of soil properties with chemical and microbial analysis.  We quantified P-cycling microbial communities using qPCR to estimate bacterial and fungal abundance and p-cycling genes and used high-throughput sequencing to estimate microbial community diversity.  Data are from 3 dunes with four representative sampling locations.  Each sampling point consisted of the removal of a block of soil 25 x 25 cm to a depth of ~25 cm to obtain both the organic horizon and mineral soil immediately beneath: n = 24.
