Nutrient uptake rates of natural phytoplankton taken from the Belgian coastal area have been assessed. On the one hand, we used a perturbation technique, this provided a drastic modification of the external substrate concentration. On the other hand, it was done by a dynamic method, which allowed a gradual and slow change of the external substrate concentration.The obtained uptake rate versus substrate concentration (nitrate-nitrite) curves show that the maximum uptake rates range from 8.6 x 10/3 h/1 to 18 x 10/3 h/1. From these curves also can be deduced that nitrogen ( as NO3- - NO2-) can be a limited nutrient in our coastal area.
