I know that most of  soil minerals ends up into the seas and oceans .

if it so we don't have to look any further to get the minerals into our soil .

here in Egypt I know farmer from different place spry salt into their clover fields  before they flood their filed with water

and they assure me with the great results they get and how green clover get , am talking here about very fine fertile clay soil


so is there a way to make use of the sea salt ?

is there a way to get the best of it ?

can we add some to the compost ?

It's not uncommon to dilute sea "water" at a rate of 10 parts water to one part seawater. If you are dealing with the extracted mineral (no water ), some googling and math should get you to the same ratio.

I don't have answers for you, but I can relate what I do on my own farm.

I collect seawater from the ocean about 15 miles from my farm. 3 times a year, using a handheld watering can, I lightly sprinkle my growing beds. I use enough just to wet the entire surface of the soil, but not soak into the soil below the surface. Because I do not have a high salt content in my homemade compost (my livestock feed is not high in salt, thus their manure is not high in salt), plus the fact that my farm experiences leeching due to heavy tropical rains, I do not see adverse salt effects in my soil. After sprinkling the seawater, I immediately lightly till it into the top 3 inches of garden soil.

You can use quite a bit more salt water on a field with out adverse things happening than most people think.
If you want to make use of sea water, then most fields can handle around 200 gallons per hectare once every 3 years.
If you are going to use the mineral salt then you can use as much as 50 pounds per 1000 sq. feet with no issues at all.

Keep in mind this is not something you do as a yearly treatment, every 3 to 5 years is a good schedule if your soil is mineral poor. 

In either case you are not going to create a "salinity" problem since you aren't saturating the soil, but instead setting up a leaching situation.
The salts will slowly work their way down into the soil, the plants will take up those minerals that become available through bacteria and fungi interactions.
The end result will be better friability and mineralization of the treated soil.

Yes, I've never seen any salinity problems yet on my farm, and the plants in the treated beds seem a bit more robust and healthy looking (though that may be just wishful thinking on my part). But the annual complete soil test comes back with better levels each passing year.

I'm a believer in micro nutrient application. Apoly a little bit at a time, but frequently. Since I'm in the tropics where leeching is an issue, micro applications works for me.

I'm just now learning more about soil science. Truthfully, I'm skipping anything that doesn't apply to my own area. This is going to be my one and only farm, so I just skim over the material about other soil types and locations. But I'm learning that different methods and results are really dependent upon one's soil type and weather. Lots of variables!

I had a friend tell me about putting salt solution on asparagus. My asparagus patch had been doing very poorly even after 4 years from planting the crowns. I made a heavy brine solution in a five gallon bucket and applied it to the whole bed. I have only applied the salt once, the first year we had decent size spears for the first time. It's been four years since I put the brine on the asparagus bed and we continue to have very large and tasty spears. All the other plants in the garden would not stand up to the amount of salt we put on this particular bed. I agree with what others have said not very much and not very often when it comes to salt. There are other ways to re-mineralize your soil and not have to worry about too much salt.  

Check out this article I wrote about Basalt Rock dust. Basalt rock dust helps grow plants

The article describes how volcanic rock dusts help plants grow better. Towards the end of the article there are descriptions of things to get you started with rock dusts.

I don't live by the ocean, but how much sea water per m2?

I usually recommend application of solution (sea water or dissolved sea minerals) of 5 gallons (20 L) per square meter.

Around here, a lot of people mix eel grass or kelp into their compost bins to get sea minerals. But we have easy access to public beaches and you can just gather up what you need from the shore. What part of Egypt do you live in? If you're in the northern part of the Delta, you might be able to gather kelp from beaches for composting.

Mostafa, yes you can make great use of sea salt on your fields and you can do it in small amounts so you don't have to worry about overdoing it.
I use about 1/2 dry Liter for every sq. m of garden space, sprinkle the sea salt as evenly as you can and you should be good to go.
In your area you should be able to do this every growing season with out any worries of build up of salinity.

Dr. Maynard Murray (1910-1982) was a pioneer in using sea minerals for agriculture : http://www.carbon-negative.us/docs/SeaEnergyAgriculture.pdf
The site of the USA company that sells these sea minerals (SEA-90) : https://seaagri.com/why-sea-90/doctor-maynard-murray/

I accidently got these sea minerals when I ordered kelp from a Belgian supplier.

That sounds really great! One of you mentioned to dilute sea water 1/10 the others didn't. How much per m2 of garden? Would shop bought sea salt do the trick?

It isn't necessary to dilute sea water, you can if you want but then you are also diluting the mineral content per ml. of water.

Sea Salts vary in mineral content all over the world, no two sites will have the same minerals present in the salt.
If you are using packaged sea salt, the good ones will list their mineral content on the package, some have been "demineralized" (Morton is famous for doing this).

If using sea water or making your own by dissolving the sea salt in water, you can use up to 5 gallons per sq. meter with no worries.

I use Sea-90 in granular form (straight from the bag) 1/2 cup per tree just sprinkled around near the drip line. For vegetables just apply as if it were Epsom salts, table spoon per plant. 

There can be issues if you don't give the ground a short rest between years of application but that is a 5 year cycle and only needs one season of rest after the five years of applications.
Your microbiota will love you for doing this, the microbiome will thrive from the addition of all those minerals.

Heya I've got some input. Sea water.salt is a common fertilizer is traditional Asian agriculture. They've got some clever methods and techniques to go about adding sea salt/water to their gardens and farms. In JADAM (Korean acronynm for "people who are like nature") farming, they take a pinch of sea salt, dissolve that into water, teabag some boiled potatoes and mash that into the water to get it nicely dispersed into the water, then they do the same with the forest soil. Cover lid of container and let ferment for 36-72 hours and wait till peak to apply at 1:20 dilution. JADAM attests that sea salt does not salinate the soil as table salt does, and that it is safely processed by the microbes, in addition to it being diluted properly.The use of fermented microbe solutions as fertilizers, scientifically referred to as biofertilizers, is popular in Asia and India. JADAM ultra low budget farming is highly effective, very easy, and very affordable to do and it, and uses sea salt. It has attributed great success to the farmers employing these fermented teas. Natural farming like this is getting to be very popular and is gaining traction slowly in the United States, most notable Hawaii (due to Asian influence in Hawaiian culture).

I have access to sea water so I use it vs buying a dried product. My thought (right or wrong) for diluting it 10:1 is I feel it will penetrate deeper in the soil.
