Those requirements are for spraying liquids. I don't think the dry fertilizer or seeding need the dertificates.Gotta have a FAA part 137 certificate (areial applicator) and an applicators license but, those are not that hard to get, just have to do some studying and take the required tests. I assume that a demonstration of the drone will have to be done in the presence of an FAA inspector.
