Nice piece Alberto

As one can see they are both limiting factors. Advanced seaweed biology books usually have a whole chapter on each. As far as concentration Carbon by far out weighs Phosphorus. The ratio of C in seaweeds, to that in water is 1.0 x 10-4 and P is 2.4 x 10-5. They are both part of Liebig's Law of Minimum, as are other nutrients. That avg ratio of C:P in seaweeds is almost 100 : 1 (97.86 : 1)or 274, 000 ug / g-l C and 2,800 ug /g-l P

An explosion can be defined as a loud noise, accompanied by the sudden going away of things, from a place where they use to be.
