Fertiliser Sourcing for Algae Growth

While going thru the posts at Oil from Algae yahoo group, I came across the following point made about fertilizers sourcing for algae growth. As the author mentions as well, this is a topic that is not often brought up in discussions, but I would guess is as important as any other topic?

Here is the note from Peri1224 (original message here)

Sourcing of fertilizer and carbon inputs

There is not much discussion in this news group of where the fertilizer nutrients (nitrogen, phosphorus and potassium) for algae culture will come from. Commercial fertilizers can be expensive but are convenient (which is why farmers use them). This is an issue since to produce algae of any species in any quantity will require a steady supply of fertilizer nutrients. There is a large body of work on the use of sewage or wastewater to supply these nutrients in algal culture. From personal experience I can say its easy to advocate the use of this nutrient source but to actually drive to a wastewater treatment plant to fill up a tank with wastewater is neither cheap nor convenient.

Nature gave us oil from algae; perhaps we should try Nature's way again
