Can I use seawater for my garden?

: Seawater is very stable at about 3.5% total mineral salts. However, water near the surface and near the shores is below that percentage.

Furthermore, Dr. Murray diluted the seawater in his experiments;
According to this document it appears he used 12% seawater, 88% fresh
water, along with some NPK*, iron and acid to balance the pH:

* According to this website, NPK was added for hybrid crops. I wonder
what heirloom plants would do? (They would benefit every bit as much as hybrids - JK)
