| Abstract/Contents: | "Nitrogen (N) and potassium (K) are vital for maintaining healthy turfgrass, but little is known about whether these nutrients affect pathogenic or beneficial microorganisms in the rhizosphere. The objectives of this study were to evaluate the composition, diversity, and distribution of microorganisms in the rhizosphere of Poa annua turf. Three 16 mm × 51 mm soil cores were sampled from four replicated plots receiving: (1) 100, 132, or 200 kg N ha-1 yr-1; (2) 200 kg K2O ha-1 yr-1; or (3) 132 kg N ha-1 yr-1 and 200 kg K2O ha-1 yr-1 (N = urea [CO(NH2)2], K = KCl). Organism-specific DNA regions were PCR amplified from fungi (ITS), bacteria and archaea (16s). Multiplexed next-generation Illumina sequencing generated 2.3 × 107 paired-end reads (avg. 1.38 × 105 seq/sample). The QIIME pipeline picked 7.2 × 105 OTUs, 4.1% of which were identified as archaea, 26.7% bacteria, and 29.7% fungi. Alpha diversity metrics showed that diversity was highest in low and high N treatments. DCA plots and Kruskal-Wallis ANOVAs revealed significant differences in microbial community structure across all treatments, particularly amongst archaea and bacteria. For example, ammonium oxidizers in the Crenarchaeales dominated K-based treatments, whereas intermediate and high rates of N favored ammonium oxidizers in the Nitrososphareales. These data show that N and K treatments can affect the composition and structure of rhizosphere microbial communities in P. annua turf." |
