Re: [APD] CO2 and Algae

I believe rugby_ox2002 at yahoo_co.jp wrote this email section below:
Hi everyone.
Physiologically and chemically, there are some points.

In cases of submerged, vascular plant, their nutrient
source, especially phosphorus, is mainly from their roots.
Vascular plant absorb nitrogen from their leaves, too; but
phosphorus is the most important nutrient for vascular
In contrast, algae, such as phytoplankton, can absorb
nutrients only from water. Therefore, to preclude the
phytoplankton growth, it is effective to decrease nutrient
levels in water, especially phosphorus.

I thought it was nitrogen (AKA ammonia) and not phosphorus that had recently been demonstrated as being the most important nutrient for plants?

Tom Barr has been quite clear on this point. :-)
