As I grow Red Ogo for human consumption, I had it analylized by an agricultural lab. I figured it would be a good resource for macro growers to use.
Ward Lab analysis for Red Ogo / Tang Heaven Red / Gravilaria Parvispora
Note: the results are for dry matter. Ogo is 92% water.
N at 2.59 %
P at 0.062 %
K at 13.54 %
Ca at 0.555%
Mg at 1.63%
S at 4.82 %
Zn at 139 ppm
Fe at 107 ppm
Mn at 20 ppm
Cu at 7 ppm
For most hobbiest the main thing to take away is that nitrate to phosphate is in a ratio of 30:1

Randy,
I found it interesting that copper was not detected in the water, within the accuracy of testing procedures, yet it showed at 7 ppm in the dry analysis.
