Seafeed Natural Seaweed Extract & Poultry Manure Fertilizer


In a nutshell....

Seafeed Seaweed & Poultry Manure Plant Feed & Natural Fertilizer

N.P.K: 4-3-3

We all know chicken manure pellets are an excellent source of nitrogen for the plants in our vegetable garden. Nitrogen is the element responsible for green, leafy growth and so is what you want for crops like cabbage, cauliflower, broccoli, kale and spinach. Seafeed goes a few steps further by mixing free range poultry manure, fish, seaweed and humic acid to create the best natural fertilizer pellet available. This is the best all round natural pellet fertilizer we're come across and is a vital part of our garden toolkit, highly recommended. Seafeed was formerly available on our site as Seamungus.

Seafeed undergoes a unique composting process which has been designed to stabalise the nutrient content and to maximise the availability of those nutrients. The finished pellets are guaranteed free of any pathogens, parasites and weed seeds.

Vegetable plants take a lot of nutrients form your garden soil and as we remove the vegetables and eat them very little of these valuable elements are returned to your garden. The benefits of adding organic materials to your garden are well known with seaweed being recognised as one of the top performers. Seaweed contains naturally occurring growth stimulants as well as a very broad range of essential minerals and trace elements which are used in the growth of strong, healthy plants.

We Supply our Seafeed plant food in 2 different size buckets; 4kg and 10kg. Please choose the required one using the Bucket Size Tab above.

Why is seaweed so beneficial?

Seaweed has been used for centuries by Celtic and Scandinavian people as a soil improver, in fact in many cases (the Aran Islands off the West coast of Ireland for example)  the soil has been entirely built on a seaweed base.

The sea is very rich in minerals and as the seaweed grows it absorbs minerals in its plant tissues which are then released and made available to plants when the seaweed is broken down. Scientists have found in seaweeds a veritable soup of plant-growth stimulants, vitamins, chelating agents, trace minerals, enzymes, and amino acids, all of which influence the growth of plants in different ways.

Studies have shown that seaweed can produce dramatic results in plants including 40 percent increase in yield from cucumbers and potatoes. Plants have been seen to have better frost tolerance, increased seed germination and a greater ability to absorb trace elements. Plants also seem to suffer less transplant shock because of the growth hormones contained in seaweed so handy as a liquid feed before planting out vegetable seedlings.

I always come back to the Seafeed great results and I've been telling everyone I know to pick up a bottle of it.
April 30th, 2020
I like the size of the product and price. i feel its good value for a good prouct and convience of use in pellet form. it arrived very quick and packaging was recycling. Very excited to see the results in the coming months.

Seaweed for your garden - in easy to use pellets. I bought Seafeed with chicken manure, after reading about the benefits of putting seaweed onto your vegetable plots and borders. I went for the 12kg bucket, as it offered great value, and offering enough pellets to do all the areas I need without running out Easy to apply, virtually odourless, so far, so good. Obviously the proof will be in how the plants themselves perform next season. I'm confident that this will be a product I come back to using, throughout the year...

Hi there would this be suitable for use with hedge plants. Kind regards jenny
Answered by Niall
on September 07th, 2021
Hi Jenny Absolutely. It is probably the best feed on the market for leaf growth which is what you are after. Just spread a handful around the base of each plant Niall Quickcrop

I’m looking to feed my raised beds soil at the end of this growing season. Would this be a good product to use ? Thanks Matt
Answered by Carmel
on July 26th, 2021
Hi Matt, yes this would be ideal to add nutrients back into your soil. It improves aeration & soil structure. You could add some of your own garden compost for some bulk too.

Asked By Louise BRADY
on September 10th, 2020
Hi Andrew, can this be used in place of rotted horse manure (in the polytunnel) , as I am concerned about aminopyralid. Thank you. Keep up the good work!
Answered by Niall
on September 10th, 2020
Hi Louise Absolutely. Actually aminopyralid or not i find i get much better results from this than raw manure Niall Quickcrop
Asked By R Lacey
on August 26th, 2020
Can I use the Seaweed and Manure in my raised veg bed around my winter kale and artichoke seedlings? Can I use it around plants in my mixed border now - tree, shrubs, perennials, etc?
Answered by Niall
on August 26th, 2020
You can of course use it for both. You are best to spread it on top of the soil and it will gradually wash down to the roots which is what you need. On the trees and shrubs etc put it about 6 inches away from the main stalk/trunk of the plants as you want it to have maximum effect for the roots Niall Quickcrop
Asked By Esther
on July 22nd, 2020
Hi is this organic please?
Answered by Niall
on July 22nd, 2020
Hi Esther The Chicken Manure comes from an Organic chicken farm and the seaweed is not treated at all so is Organic as it is from the sea but the product has never been certified due to cost. We use it on our own gardens and we garden organically Niall Quickcrop

Could you tell me the dimensions of the 10kg pot as compared to the 4kg pot as I would ideally like to order the 10kg one but a friend is going to bring it to France and I dont know how much room this will take up.I am knew to vegetable gardening and would just like to say that your you tube videos and detailed answers to questions are fantastic.Thank you.Steve
Answered by Andrew
on July 06th, 2020
Hi Steve. The 10KG bucket is 26cm, high by 32cm in diameter. It is a plastic bucket with a handle.
Asked By Lisa
on July 03rd, 2020
Hi quick crop team! I used the pellets recently and due to the never ending rain and humidity, they started to go moulds on the top of the soil. Did I do something wrong? Can I grind up the pellets to make a dust perhaps that will get into the ground quicker? Or even mix with water?
Answered by Andrew
on July 03rd, 2020
Hi Lisa. I would rake the pellets in to the surface of the soil. The mould will not be an issue.
Asked By Lisa
on July 03rd, 2020
Grind it up or mix with water?
Answered by Andrew
on July 03rd, 2020
Hi Lisa. This product is more suitable as a surface feed or mixed in with the soil. You can mix with water as a liquid feed but it will be difficult to apply with a watering can without sieving.
Asked By Daniel Walters
on June 29th, 2020
Hi, love using this. Just wondered, would this suit as a good enough feed for tomato’s please? Thank you
Answered by Andrew
on June 29th, 2020
Hi Daniel. Yes, this feed is very good for tomatoes and is the one I use although I do supplement 3 or 4 times in the season with a liquid tomato feed to add some potassium for the fruit as seaweed is not particularly high in 'K' (potassium).
Asked By Anne McGee
on April 01st, 2020
how much of the seaweed and manure mix should I apply per sq meter and is it ok to use on all my vegetables i.e. turnip, carrots parsnips, beetroot and peas. Should I also use it to sprinkle around my fruit bushesnd pple trees. Thanks
Answered by Niall
on April 02nd, 2020
Hi Anne About 1 large handful per square metre and yes it is good to add to the soil for all veg and fruit. Just go easy on carrots and parsnips and don't feed blueberries Niall Quickcrop
Asked By Andy
on December 05th, 2019
What's the best way apply this if you are using the grow grid. Is it best to dissolve the pellets ?
Answered by Niall
on December 06th, 2019
Hi Andy If you don't have the Grow Grid down yet you can just scatter it on the surface one large handful to a square metre. If the Grow Grid is down then you can put it in water and water it on but it might be easier to just work your way along and put a few pellets in each hole. Time consuming but worth it Niall Quickcrop
Asked By Judith Cassingham

Is this product safe to use in gardens where dogs live?
Answered by Andrew
on October 22nd, 2019
Hi Judith. Yes, this product is safe for use where dog are present but in rare cases we have heard of puppies digging up beds when the pellets have been first applied.
Asked By Vinay Rathore
on October 05th, 2019
Hi, Does it contain Calcified Seaweed? Does it impact ph value of the soil ? Can I use it in pine (which is acid loving plant)? Thanks Regards, Vin
Answered by Niall
on October 08th, 2019
Hi Vinay This is made with Seaweed meal so it doesn't have large amounts of calcium in it. As a result it doesn't effect the PH of the soil and you can use it in an acid soil Regards Niall Quickcrop

Answered by Niall
on August 13th, 2019
Hi Jane It is for the first few days i'm afraid. Once the elements get at it the smell does go away but if you have a dog that loves smelly stuff he will be on to this in a light Niall Quickcrop

Do you know the source of the chicken manure for this product? I am concerned about antibiotics, heavy metals, GMO feed, E coli, salmonella and other nasties associated with intensive chicken farming which could end up in the chicken manure. It is sad I have to even ask this question. Many Thanks
Answered by Niall

Hi Peter We do. It is from an Organic chicken farm in Monaghan Ireland and the product is cleared as Organic as the seaweed is obviously organic as well Niall Quickcrop

Answered by Niall

Hi Lesley The Coir already has nutrients added to it so 7 bales of the coir will be sufficient to fill the 1.8m Vegtrug and be good to plant in to straight away Niall Quickcrop
Asked By Kevin Broaders

A few years ago, I researched the constituents of Seamungus. If this is the same product with a new name - is the 'Amino Acid' part still being sourced from coal?

Hi Kevin. No, the Seafeed product is made from composted seaweed and free range poultry manure only. It does not contain coal sourced humic acid.

Is Sea feed suitable for potato plants , And can you give your recommendations for growing same please?
Answered by Andrew
on April 24th, 2017
Hi Mary. Yes, Seafeed will be suitable for growing potatoes but I would be sparing with it as you don't want too much nitrogen or you will get too much leafy growth. I include a link to our video on growing potatoes which I hope will help: https://www.quickcrop.ie/learning/video/potatoes
Asked By Mike Harris
on April 15th, 2017
what percentage of the product is seaweed, how much chicken manure and how much fish meal?
Answered by Andrew
on April 18th, 2017
Hi Mike. The ratio of chicken manure to seaweed is approx 70% manure and 30% seaweed meal. The product does not contain fish meal.
Asked By KR
on March 18th, 2017
Hello, I have had mine since last year with the lid on tightly but I have opened it and the pellets are still mostly separate but they are a bit mouldy/furry. is it still ok to use?
Answered by Andrew
on March 20th, 2017
Hi KR. Yes, the seafeed is still fine to use in the garden. Molds develop most often when there is sufficient moisture and a lack of air, so common in bagged compost and/or manure.
Asked By Andy
on February 21st, 2017
Where does the poultry manure come from? I realise it's great for plants, but I don't want anything that's come from any kind of intensive farming!
Answered by Andrew
on February 22nd, 2017
Hi Andy. A very good question. It actually now comes from Organic chicken farms. The product is not fully certified Organic yet however it will be very soon. We know this manufacturer very well and he is very conscious like ourselves of doing things the right way so rest assured it is not from intensive farms.
Asked By Tiffany
on May 10th, 2016
Is the seaweed/fish material ethically sourced, how is it sourced, and where from? Where is the chicken manure sourced from and is it from organic/free range chickens? If not, what are the conditions in which the chickens are raised?
Answered by Andrew
on May 10th, 2016
Hi Tiffany. Good questions. The fish meal is the waste from the fish factories in North Donegal Ireland and is all from registered fish factories. As regards the ethics of fishing i will leave that one up to you. The chicken manure is from free range farms but not Organic. I am afraid for a farm to be registered Free range the chickens only have to be allowed outside on grass for 1 hour a day so again not 100% sure on the ethics of that. I can't imagine there is any product on the market that ticks all of the ethics boxes which is a shame but this is the closest we can find.
