A new research paper shows a large and significant negative effect of the major plant nutrients (NPK) on the abundance, species richness and functional diversity of both pollinators and flowering plants. Even average use of nitrogen fertilisers cut flower numbers fivefold and halved pollinating insects. This isn't a novel finding but the data presented is incontrovertible. This helps to explain the lack of biodiversity in huge swathes of VC55.
