i think the nitrate theory falls right in there because, although the plants can uptake ammonia and nitrite, they have to break it down first, much like the bacteria, so the uptake is so much slower. is that what you were thinking?
Plants can take ammonia up as is as far as I know.
It's just an observation I've made. I'm not sure what the science is behind it.
