Thanks so much for posting those articles. There is so much in them that, for me anyway, they will require more than one reading over more than one day.

Dr. Bachmann's article concluded that there was little or no relationship in the Florida ponds studied between water column nutrient levels and aquatic plant biomass. He theorized that the plants obtained most of their nutrients from the soil in which they grew.

I wonder if there is a similar study of ponds that were dominated by plants that obtained their nutrients from the water column, like hyacinth and myriophyllum. I bet the conclusions would have been different. Right?
