How Can Synthetic Fertilizers Modify the Detectability of Flowers?

A couple of different species of insects are able to detect electric fields in air. The way they do this is that hairs on their body get pushed around by the electric field. It might give these bees a bit of a clue as to whether and there's a good amount of nectar in that flower or not. What is it about synthetic fertilizers that alters the detectability of these flowers? We try to unravel this a little bit in our study.
