Have you read Diana Walstads' book?

ECOLOGY of the PLANTED AQUARIUM - A Practical Manual and Scientific Treatise 
for the Home Aquarist.

I've not got a copy to hand today. But I think it covers these topics.


Perhaps try Googles' book search?

It's a very fine book. Essential for the serious aquarium keeper.

A link to some of Dianas' articles on plant growth are on the bottom of that 
AWE article.
