Bacteriome of grassland fertilized with ashes and struvites
To investigate the impact of different phosphorus fertilizers on plant growth and the soil P cycling microbiota, a short-term pot trial was conducted (54 days). Lolium perenne was grown with application of superphosphate (SP) as inorganic fertiliser, two ashes (poultry litter ash (PLA) and sewage sludge ash (SSA) and two struvites (municipal wastewater struvite (MWS) and commercial CrystalGreen (CGS) in rates of 20 and 60 kg P ha-1 in four replicates. A P-free control (SP0) was also included in the trial.
