Sea Minerals Fertilizer – My Favorite Fertilizer

Sea Minerals Fertilizer

If you’re lucky enough to live right beside the ocean, I’m envious of not only your view of the surf, but the incredible fertilizer you have at your doorstep.

Sea minerals fertilizer is definitely my favorite organic fertilizer. It has very noticeably improved the health and increased the growth and yield of many of my plants.

It’s more expensive than liquid seaweed and fish, but the application rate is lower so it ends up costing less.

Rivers and volcanoes have been adding minerals to the sea for hundreds of millions of years, which is why it’s so nutrient dense in there.

That’s what we need to emulate in our gardens.

Fortunately these days, we all have access to it, even if we live far away from the sea…

Benefits Of Sea Minerals Fertilizer

Yes, the ocean has salt, but it also has over over 80 other minerals that are immediately available to plants upon application.

On the other hand, seaweed fertilizer and fish fertilizer and most organic fertilizers need to be worked on by microorganisms first – not a problem if you’re ensuring these microorganisms are there, but just an extra step in the process.

Dr. Maynard Murray was one of the early pioneers of using sea minerals for fertilizer. He purchased a farm and started bringing railroad cars of ocean water in to fertilize it.

He got bigger yields, tastier and more nutritious food, far fewer pests and just healthier plants in general.

How To Use Straight Ocean Water In The Garden

If you’re lucky enough to live near the ocean, you don’t need to go through the process of concentrating the sea water down and removing the sodium chloride.

Certainly, there are benefits to that, but there’s also something to be said for walking out your door and getting some free fertilizer.

Of course, you don’t want to use ocean water from a polluted bay, but if your little piece of sea is relatively clean, go for it.

As for application rate, early experiments showed that various plants would take anywhere from 1200-3000ml of sea water per square foot of soil. That’s a lot! Apparently 1 application would last for 5 years.

If I’m doing it, based on what I’ve learned, I apply more like 1 teaspoon diluted in 3 Tablespoons of water (1:10 ratio) per square foot (5000ml of ocean water per 1000 square feet), 4 times per year every year, for both foliar and soil applications.

But most of us don’t live by the ocean. Fortunately, there are a couple of companies doing a really good job of concentrating that sea water down into a liquid fertilizer while still retaining the important constituents of the water.

Finding A Quality Sea Mineral Fertilizer

Sea Minerals Fertilizer On Apples

The product I use is called Sea-Crop and I’ve been using it for many years. Thirty gallons of seawater are used to make 1 gallon of this concentrate.

There are a couple of reasons I like it more than the other ocean fertilizers I’ve tried:

  • The first is that 95% of the sodium chloride is removed. Now in my view, this isn’t as big of a deal as the manufacturer contends, as I believe the sodium and chlorine are just part of the natural balance of sea minerals, but what I do like is that have less sodium allows for a higher application rate than could otherwise be used.
  • But the bigger reason I like this product is that they do a great job of retaining the microscopic organic component of the water – the dead (and perhaps some living) microbes and plant matter. I’ve done a lot of research into the various methods of processing ocean water and usually this component is substantially decreased, especially in sea solids fertilizer such as ‘Sea Minerals FA’ and ‘Sea 90 Fertilizer’, therefore so is the effect on plants (these are still fine products and certainly useful in some cases, but I prefer the much more alive Sea-Crop).

And here’s an email from a biology student who took it upon himself to test the product:

“My name is Josh, I bought 1 gallon of Seacrop at the 2015 Tilth and promised a subjective microscopic analysis. For the procedure, I filled mason jars 3/4 with deionized water and added the exact same weight of inoculant (containing bacteria and fungi) to each container. Subsequent additions of kelp extract and fish emulsion were identical between samples, as were temperature and oxygen components. The only perceivable discrepancy amongst samples was addition of Seacrop to only one sample. The difference in bacterial population was astounding, where the non-Seacrop sample had no bacteria and the sample with Seacrop was exploding with a diverse range of beneficial bacteria. Good job on a great product that works better than I could have imagined!” Joshua Peterson, Entomological Aide and Biocontrol Technician, Wenatchee Valley College

How To Use Sea Crop In The Garden

I recommend 1/3 cup of Sea Crop mixed in 1 gallon of water per 1000 square feet, 4 times per year.

That works out to nearly 1 1/3 cups per 1000 square feet per year.

But here’s more detail.

Annual application rate recommendations from the manufacturer:

  • Garden Produce: 4 gallons per acre (1.5 cups per 1000 square feet).
  • Row Crops: 2 to 4 gallons per acre (0.75-1.5 cups per 1000 square feet).
  • Trees:
    • 3-6 feet tall: 1/2 cup per tree, not to exceed 10 gallons per acre.
    • 6-12 feet: 3/4 cup per tree, not to exceed 10 gallons per acre.
  • Lawns: 2 to 4 gallons per acre (0.75-1.5 cups per 1000 square feet).

In my garden, I alternate every other month with liquid fish fertilizer (eg. fish in March, sea minerals in April, fish in May, etc.).

I suggest mixing it with at least 50 times as much water, which would be 1 gallon of water for each 1/3 cup of sea minerals. Or just set a hose-end sprayer to spray 5 Tbsp per gallon.

Sea minerals is great mixed with liquid seaweed and microbial inoculants.

Note: The manufacturer of this sea minerals product says it’s best not to apply it in the same spray as liquid fish in order to keep its effectiveness optimal – I’m not sure how big of an issue that is, but it’s one reason I started alternating them every other month. They also provide some of the same benefits so it makes a lot of sense to alternate between them.

You can also soak seeds overnight before planting at 1 teaspoon per cup of water. You can optionally mix in an equal amount of liquid seaweed fertilizer.

    I DO live by the ocean, 8 blocks away actually, and I live right off a canal connected to the ocean, so I have great access to both ocean water and seaweed. So, if I were to use the sea water, you said 1 teaspoon per square foot, so does the sea water get diluted? I also asked this before, but doesn’t the salt harm the plants?

    • Phil on April 1, 2014 at 1:36 pm

      Yes, I would dilute it with 10 parts water. You’d think the salt would harm the plants, but it generally doesn’t. There may be certain plants that are especially susceptible to salt damage, but they probably wouldn’t be doing very well 8 blocks from the ocean anyway.

      • Brian Michael Shea on April 1, 2014 at 4:08 pm

        Thanks Phil. I’m going to try it today. Oh darn, I have to go to the beach…… 😉

        • James on January 5, 2016 at 1:35 am

          2 years later. What has been the result of your experiment?

          • Brian Michael Shea on January 5, 2016 at 5:50 pm

            i honestly don’t remember where i used it, if it was on the beds in the courtyard, it worked great, on my veggie plot, so so. i’ve used more seaweed actually. i think my veggie plot needed to get more organic matter and build fertility, and seems to be getting better, whereas the soil in my courtyard was already pretty good.

    • debra houseman on May 22, 2017 at 9:17 pm

      i have a 2 gallon ez flo system. how much do you add and how do you know when you have gone through it since it is constantly hooked up to a water source. and no other fertilizer then for 3 months? sounds good but i am so used to fertilizing at least once a week. thanks.

      • Phil on May 30, 2017 at 8:58 am

        Sorry Debra, I’m not sure how the ez flo system works. Do they give you a way of determining the dilution rate?

  2. Bear on April 30, 2014 at 5:24 pm

    My Gilmore hose-end sprayer is set on 1 tbs per gallon when I spray a molasses/liquid seaweed/BioAg mixture for my 1000 square foot growing area. Could I add some sea minerals to this mixture and, if so, how much? Thanks.

    • Phil on April 30, 2014 at 7:03 pm

      Sure, I use 1/3 cup per 1000 square feet every month or two. That dilution rate is plenty, so you’re good to go.

      • Bear on April 30, 2014 at 9:55 pm

        Thanks! I’ll order some of your sea minerals today. Also, FYI, the video at the end of this academy lesson doesn’t work (“YouTube Remineralization”). The message I get when I select it is: “This video does not exist.” Thank you again for your academy and your willingness to answer questions. Our neighbors are beginning to ask questions like, “Okay. What are you doing differently?” So people are noticing an improvement around here.

  3. Terri Hamilton on May 25, 2014 at 11:18 pm

    Does this product contain iron?

    • Phil on May 26, 2014 at 12:05 pm

      Yes, it contains trace amounts of iron and every other mineral, but not too much of anything. For iron, it’s 15 parts per million.

  4. James Rose on July 28, 2014 at 1:26 am

    this is absolutely staggering

  5. Vijayan Muthu on August 3, 2014 at 2:00 am

    Hi Phil, I am VIJAY from Malaysia. I do practice using beneficial microbs in my garden. By using sea water 1:10 does it harms the mychorriza networke, trichoderma, paecilomyces lilacinus and I do all so use becillus subtilis, pseudomonas fluorescens and many other microbs .

    • Phil on August 3, 2014 at 7:35 pm

      As long as you don’t use too much, it will be fine. I even combine sea minerals with my inoculants sometimes.

  6. marko on October 30, 2014 at 8:18 pm

    Do I need other fertilizer with sea crop, or is the sea crop everything that I need for my garden? Thanks

    • Phil on October 31, 2014 at 7:16 am

      Fertilizing is a bit more complicated than that, but what I can say is that sea crop is the only fertilizer you need for supplying micronutrients. For macronutrients, you may need some specific minerals such as calcium and phosphorus, which can only be discovered by sending a soil test to a good soil lab to see what you have.

  7. Nelson on April 24, 2015 at 4:01 pm

    Hi Phil, I am Nelson from Malaysia. Out of curiosity, some suppliers said that this brand and most sea minerals fertilisers are just water mixed with nitrate (synthetic), is it correct? Additionally, I tried to google abt the minerals analysis for Sea Crop, but I couldn’t locate any yet… If you have, mind to share the content here?? 🙂

    • Phil on April 24, 2015 at 6:26 pm

      Hi Nelson, the few sea mineral products I know of (including this one) are some form of concentrated sea water with nothing else added at all. This one here is even registered organic, so no synthetic nitrates for sure.I have seen an analysis of Sea Crop somewhere before, but no, I don’t have it right now. I’ll let you know if I ever find it.

      • Nelson on April 25, 2015 at 9:43 am

        Thanks for your explanation Phil :)Recently this supplier has approached me with Liquid Ionic Concentrated Mineral Fertilizing Water, what he mentioned is this is derived from the ocean water too from Arabian Ocean, and he is using membrane filtration and some unique method to extract the minerals in which is different with the method used by Sea Crop/ Ocean Trace, SEA-90 if I am not mistaken.Phil, since you are an expert in farming, what’s your comment on above? 🙂

        • Phil on April 25, 2015 at 12:54 pm

          Sorry Nelson, I’ve never heard of that product and can’t find any information on it online.

          • Nelson on April 26, 2015 at 5:24 pm

            That’s what I thought. I couldn’t find anything when i googled that. Thanks Phil! Appreciate your help

  8. MendR on July 24, 2015 at 2:51 am

    Hi, I’m on ocean in Fla. Do I just dive down and get a bucket full of seawater? Heard it wasn’t concentrated enough. What do you think? I’m very new to all of this, but very interested. Please advise Thanks.

    • Phil on July 25, 2015 at 6:24 pm

      Yes, I use 5 quarts per 1000 square feet, mixed in 10-15 gallons of water and watered onto plants and soil. It’s not nearly as concentrated as the sea mineral fertilizer products available, but it’s still full of minerals (which you can taste when you go swimming).

      • MendR on July 26, 2015 at 5:30 pm

        Phil: How often should I treat w/sea salt? Once a month? year? Also, should I skim the top of the ocean water, or jump from boat, in and go a few feet under to harvest? Thanks for responding.

        • Phil on July 28, 2015 at 4:08 pm

          I do it 4 times per year. Skimming off the top of the ocean is perfectly fine.

  9. Richard on March 28, 2016 at 3:05 pm

    After you dilute the sea water how do you apply it? I assume I would be applying to my plants?

    • Phil on March 28, 2016 at 10:34 pm

      Yes, you can dilute it in a standalone sprayer (like a backpack sprayer) or use a hose-end sprayer (which then does the diluting for you) to spray it onto your plant leaves – and the soil as well.

  10. BeN on April 18, 2016 at 10:46 am

    I have been given some dead sea mud, is it beneficial as a fertilizer?

    • Phil on April 19, 2016 at 4:16 pm

      Hmm, I’m not sure Ben. Do you have an analysis of what it’s comprised of? And any kind of mineral analysis?

  11. BeN on April 20, 2016 at 6:02 pm

    For comparison, below is a typical sea water analysis:Magnesium 0.13%Sodium 1.07%Calcium 0.04%Potassium 0.04%Chlorides 1.9%Bromides 0.007%

  12. Richard on May 24, 2016 at 4:09 pm

    I am a bit confused, I wrote to you yesterday about settings when applying ocean water using the Gimour hose end sprayer to a 250 Sq Ft garden. Your response was ” Setting 10 is 10 Tbsp per gallon, which is a 1 to 25 ratio, so that’s plenty diluted”. How much undiluted sea water am I supposed to put in the hose end sprayer and then apply using setting 10? Thanks, sorry for the confusion

    • Phil on May 25, 2016 at 8:01 pm

      The research has been all over the map about how much to apply, but I’ve settled on applying less ocean water, sprayed more often, in order to avoid applying too much at once.I do 5 liters per 1000 square feet 4 times per year, which would be 1250ml per 250 square feet, or exactly 1/3 gallon of ocean water. So ya, you’d have to make a few passes with the little Gilmour. As for the dilution rate, setting 10 is the highest setting the Gilmour does, which is perhaps unnecessarily dilute, but that’s fine.Alternatively, to speed things up, you can use a watering can, and a 1:10 ratio is fine, which is 375ml (1.5 cups) per gallon of water. So that’s 3.3 gallons of water for your 1/3 gallon of ocean water. Hope that helps.

  13. lindasunderlin on July 28, 2016 at 10:24 pm

    I have two young apple trees and my raspberries that are yellow and not doing well. I have addediron and magnesium and it last a short while and then they are yellow again. How much sea crop would you give a 6-7 foot apple tree and raspberry plants that are in a row? Thanks

    • Phil on July 31, 2016 at 2:45 pm

      I generally think in terms of square footage: 1/3 cup per 1000 square feet, 4 times a year. Twice as much for fruit trees.RASPBERRIES:If the raspberry patch is 3 feet by 50 feet, that’s 150 square feet. At 1/3 cup per 1000 square feet, that’s a little less than 1 Tbsp for the raspberries – 4 times a year.TREES:Here’s what the sea minerals product developer says for trees:Medium size trees (size 3-6 feet): use 4 oz. SEA-CROP® seawater concentrate per tree, not to exceed 10 gallons per acre per year.Large trees (size 6-12 feet): use 6 oz of SEA-CROP® concentrate per tree, not to exceed 10 gallons per acre per year….Depending on tree size, I would use 1-1.5 oz (2-3 Tbsp) per tree – 4 times a year.

  14. Ken on February 21, 2017 at 12:31 pm

    Sorry there is no scientific proof that see water benefits terrestrial flora and plants cannot use or process the sodium. Good organic soils such as using plain dark compost will better promote good microbes to break down nitrogen and other important micro nutrients.

    • Phil on April 4, 2017 at 2:28 pm

      There’s actually a lot of scientific proof, Ken. Not sure if you have access to the research, but you’ll find it there, and even Google will turn up a few things. And yes, plants not only can process the sodium, but they need it – it’s an important nutrient for them.

  15. Ken on February 21, 2017 at 12:34 pm

    Yellowing of fruit trees is basically a nutrient & lack of nitrogen problem or could be poor drainage -hence the leaching of nutrients. Also there is no mention of sun exposure and the amount of hours the trees receive. Sorry no amount of sea water is going to resolve that issue.

    • Phil on April 4, 2017 at 2:30 pm

      Yellowing of fruit trees can be caused by a great number of things, not just nitrogen deficiency and poor drainage.

  16. David Christoffer on April 10, 2017 at 9:55 am

    I farm and am not organic but am interested in using sea salt. Raise corn and soybeans. Have 500 acres but would not be interested in doing the whole farm yet. Right now am interested in knowing a. the availability of your product for this size acreage b. the application rate/year c. the preferred application method ie. broadcast on the soil surface and or applying it in the seed trench d. rough estimate of the cost/year d. do you have any producers that have used you product on a large scale?

    • Phil on April 14, 2017 at 12:51 pm

      a. Yes, if you email me your shipping address and the acreage you want to buy for, I will quote you.
      b. The annual application rate is 2-4 gallons per acre, generally divided into 3 applications, usually in the spring, each one about 3 weeks apart.
      c. It’s broadcast as a soil drench and foliar fertilizer at a 1-2% dilution rate with water. Often 1 of the applications is before emergence and the other 2 are after, although they can all be done after.
      d. For 500 acres, I’d say about $30/acre.
      e. Absolutely. If you email me, I can share some examples.

        I have some SEA 90 dry sea salt ( I thinks that is the name of the product I bought years ago) I am trying to find out what rate of the dry salt (dissolved and diluted) I should use on a per acre basis. Can you help mw with this.

      • David Christoffer on January 8, 2018 at 12:25 pm

        You indicated that you could supply me with some examples of large scale farmers that have been using sea 90 as a drench and/or foliar. Would appreciate it you would do that.
        Thank you Dave

        • Phil on January 15, 2018 at 8:10 am

          I don’t have anything on soy, but agronomist John Kempf had these findings:

          Corn ~ 2,000 acres, 2 gallons Sea-Crop per acre in the furrow.
          Result: Made plants stronger and increased yield by 10%.

          Popcorn ~ 200 acres, 2 gallons Sea-Crop per acre in the furrow with a microbial inoculant.
          Result: The neighbor across the road on the same type of soil planted the same variety of popcorn. The neighbor used 200 pounds of nitrogen to the acre and the Sea-Crop farmer used 40 pounds of nitrogen. The Sea-Crop treated popcorn gave a 40% greater yield using 80% less fertilizer. The Sea-Crop treated field was ready for harvest 20 days earlier than the conventionally treated field.

    if you do a drench for transplants for a 30 ft row, how much diluted sea minerals per transplant

    • Phil on December 30, 2017 at 7:36 pm

      If the row is 1-foot wide, I would use 1/2 teaspoon (5 ml) of Sea-Crop (or if you’re using ocean water, use 1/3 gallon) diluted in as much water as you need to do the drench. Do this 4 times/year, whether as drenches or foliar or a combination.

      • Denise on April 20, 2020 at 1:36 pm

        Is that 5ml for each transplant or 5mls for the 30-foot row?

  18. Helga Wells on April 16, 2018 at 9:57 pm

    Could the sea minerals be used for aquaponics. I am looking for an alternative, since the “supplements” you use for the Tower Garden are not organic. Thanks

    • Phil on April 17, 2018 at 10:22 pm

      I know it’s used in hydroponics at a 1:100 ratio (2.5 Tbsp per gallon of water).

  19. Dale on April 21, 2018 at 2:57 am

    Did Mr. Murray figure out if the naturally occurring halophilic bacteria and archea in the ocean solids contributed to the positive results on crops? Bacteria from the ocean can be found growing on cheese rinds that have been cured using sea salt and in other foods that have been brined or preserved with sea salt.

    • Phil on April 21, 2018 at 8:49 am

      Good question. I could be wrong, but my understanding is that Murray discounted the biology. What I do know is that the people who make the product discussed on this page believe the biology is of paramount importance and have taken great lengths to preserve it. That’s one reason why the product is liquid instead of solid (because a lot of the biology dies in the dried sea mineral products) and also why the container is opaque, to protect the biology from ultraviolet light.

  20. Tom Z on June 2, 2019 at 2:14 pm

    I have real salt which is harvested from mines in Utah USA. It has 80 or so trace minerals. Is this a good additive for gardening?

    • Phil on June 3, 2019 at 11:00 am

      Definitely. The application rate recommendation I’ve seen most often is 1 pound per 1000 square feet annually. I’ve seen as high as 10 pounds but to me, that only makes sense if you have a documented sodium deficiency in your soil.

      • Tom Z on June 4, 2019 at 11:20 am

        So do you recommend I add dry or dilute? I’ve seen growers add dry to soil on youTube.

  21. richard verret on June 24, 2019 at 5:24 pm

    i have all potted plants, many are large and some small.
    should i dose with one teaspoon (diluted) per sq foot?
    what is recommended for potted plants?

    • Phil on June 25, 2019 at 9:51 am

      The application rate, a few times a year, is 1/3 cup per 1000 square feet, which is about 1 teaspoon per 60 square feet or .08 teaspoons per square foot. The dose is very small because it’s so concentrated.

  22. Larry on June 26, 2019 at 9:07 pm

    I am on a two-week spray schedule, alternating each time between Liquid Fish and Sea Minerals – the base spray is 2 Tbsp Molasses, 2 Tbsp Bio Ag, and 2 Tbsp Liquid Seaweed, in 2 Gallons Water. I have also been doing a monthly soil drench with Compost Tea. This is in addition to the plants being mulched with homemade compost. The growth and health of the vegetable plants is nothing short of amazing! And, for the first time, the squash plants have not developed powdery mildew as they normally due during the humid summer days.

    One thing that is not clear, though, is the recommendation that it not be sprayed when plants are flowering. Plants such as peppers, tomatoes, and cucumbers are in a state of constant blooming. If those plants were not sprayed while in bloom, they would never be sprayed. But, since there has been no decrease in fruit set since starting to spray, I am not sure the reason for recommending not spraying when in bloom. Any thoughts on this?

    • Phil on June 28, 2019 at 6:10 pm

      I’ve heard rare stories of plants deflowering when hit with EM, hardly ever, but I just like to be safe. Sounds like it’s working great for you so keep going!

      • Larry on June 28, 2019 at 8:31 pm

        Thanks, Phil! Fortunately, I have not experienced any bloom drop up to this point. I’ll watch the plants following sprays to see if there is any noticeable change in the blooming of the plants.

      i guess you didnt understand my question

      i need the mix ratio of sea mineral fertilizer and water for potted plants.
      based on an application every two weeks

      i dont need help with molassas and all that other stuff

      also, its been about a month since i ordered sea mineral fertilizer and havent received it yet

        Hi Richard, I don’t have a record of a question from you or an order from you, but to answer this question here, for potted plants with application every 2 weeks, I would mix 1/4 teaspoon of sea minerals per cup of water and spray the plant foliage with that.

          i need another dosage formula i cant use the foliar one you gave me my plants are all indoor potted plants and i cant spray them for many different reasons.
          all i can do is normal indoor watering where each pot has a medium size drop pan.
          watering levels are from 4 oz per plant up to about a gallon per plant.
          what mix do i need for every two weeks a mineral watering?

            In that case, I would use just 1/2 teaspoon per gallon of water. It’s not a lot per watering but will add up when watering every 2 weeks.

            Might be able to help you here. Check out the commercial greenhouse bean trial:

            Their T6 application resulted in a 68% increase in product mass. Application and concentration rates are discussed throughout, but the “winning formula” for them is found on the last page of the PDF.

            I’m container gardening as well, and plan to follow their instructions, as they seem to jive with the other recommendations that have been made here and other places. Mine source is Christina at, but the product is made in Washington state so if you’re in the U.S. you can source it from Phil up above.

            Hope that helps.
