Nitrogen fertilisers shape the microbiota thriving at the root-soil interface in field-grown tomato

In the present study we evaluated the effects of different forms of nitrogen on the processing tomato yield and quality and on the recruitment of bacteria at the root-soil interface. To investigate the effects of different form of nitrogen fertilizers on processing tomato microbiota, a single hybrid of processing tomato was cropped in open field. Seven different fertilizers (pelleted digestate, liquid digestate, slow-acting liquid digestate, organo-mineral fertilizer based on digestate, synthetic fertilizer, slow-acting synthetic fertilizer, and no fertilization) were applied and the composition of processing tomato microbiota was characterized by a 16S rRNA gene sequencing analysis.
