I need my water tested professionally to help me with my future business as a commercial hydroponic farm. I'm running into a few problems here in Taiwan. I'll probably have to get it tested in the US. So I need some help from you good people with these questions:

1. Where can I get my water tested for ppm of N, K, P, Fe, Na, Ca, S, and magnesium?

2. Will they do a sample sent from Taiwan?

3. How much will it cost? My current bid from a Taiwanese company is in the range of $4,000 US dollars.

Taiwanese farmers never test their water or soil, so the whole idea of testing it is very strange for them in the first place. I'm going to try going through the Agriculture dept. at National Taiwan University, but I would feel better doing it through a US company.

Thanks,

Okami
