RE: Nitro in the Pond?
In the 11 years that my club has had the farmground we fly on, the adjacent crops have improved in yeild. I don't attribute this to the glow fuel oil residue, but there appear to have been no noticible effects to the ground and crops.
However, two years ago, I fear, some mutation or other caused our normally docile ladybug population to become bitter and angry, and develop the capacity to bite. I fear it's a fuel induced mutation, or they just rebel against our invasion of their tranquil space. It's only a matter of time until they mutate into larger, more vengeful species, and take us all out. Beware.
Good luck,
Dave Olson
