Seawater can also be left to completely evaporate, and the remaining salt will contain all the other minerals present in the original seawater. It's all these other minerals that really benefit a soil and the soil microbial life.

I had that exact question in my mind. Thanks for the answer. I did a test batch of evaporating seawater. At some point i had a lot of salt in the water. It seemed to me that "scooping" the salt out of the water would be better than "scraping" the salt out after fully dried. This would leave a mineral rich water that i could dilute and apply on my trees.
I have access to seawater once a month and bring back a few gallons each time. I have plans to build a solar dehydrator and use it to evaporate it.
