Besides, natural fertilizers are usually dead plants, because it's forbidden to use dead animals or animal excrement as fertilizers, because they might contain dangerous bacteria that can attack both humans and those animals, and which can survive being outside of host for some time. For similar reasons, though not quite as strong, it's safer to use synthetic fertilizers rather than dead plants.
