Seaweed is one of the best gifts you can give your garden as it has long term positive effects on your soil and your plants. Seaweed meal is a ground and concentrated alternative to adding fresh seaweed to your garden, it is dry and easy to handle and store.
Seaweed meal contains:
Alginates
Alginate gels vastly increase the microbial population in your soil. Soil health and plant growth are directly proportional to the concentration of soil microbes, large microbial populations mean larger, healthier plants. Alginates also absorb large quantities of moisture which increases moisture retaining capacity of your soil. Alginate is present in seaweed meal at levels of between 16 and 26%.
Growth Hormones and Biochemical Compounds
Seaweed meal contains a range of beneficial plant hormones and biochemical compounds. The plant hormone cytokinin promotes plant cell division and growth thereby increasing yield. Cytokinin has also been shown to strengthen plant immune systems making them better able to cope with pests or disease.
Insoluble Carbohydrates
Insoluble carbohydrates in seaweed meal acts as a soil conditioner (improves aeration & soil structure, especially in clay soils).
Seaweed meal:
Increases yield.
Improves germination.
Increases uptake of soil nutrients.
Increases resistance to pests/insects.
Increases resistance to frost.
Is 100% Organic

5 Seafeed Organic Seaweed Meal Soil and Plant Feed
Cleared the last of the veg (and weeds) from our raised beds. Into the fourth year now and need to replenish soil. This was the best all purpose option for adding to soil now, very easy to sprinkle over beds. Looking forward to good crops next year.

If so, given the area involved, would 2 bags do the trick for an initial feed, followed by annual dosing therafter?

To be honest if you have stripped the soil back to that extent you really need to build new soil up and Liquid feeds or seafeed is not the right thing. These feeds are for existing soil to build the nutrients in the soil to feed your plants but as they are not a bulking agent they won't add much volume to the area which is what you need. I am afraid your suggestion of composted bark and manure plus topsoil is your best option but as you say will be expensive

The site is on sand (both topsoil and subsoil) and the turf has been neglected. An external contractor has been responsible for cutting the grass since the playing field was resurfaced several years ago, resulting in compaction and generally unhealthy turf.
As the playing field doesn't need particularly high quality turf but the site owner would like healthy turf all year, I initially plan to aerate (probably using a towed slit aerator as a result of budget and time constraints), and then feed and overseed at an appropriate time (hopefully soon, but possibly when the weather conditions are right early next year). Ongoing site maintenance would follow the same basic See more »

It is very loose and may travel through the mechanical system you are using to easily and as a result to much might be applied over a smaller area. It may be best to get a small amount first and try it. The product itself is perfect for what you are looking to do it is just whether it will work with your applier

That is fine. The seaweed meal is essentially for building plants immune systems and helping feed and look after plant health. The Seafeed is more of a slow release to feed the roots of the plant. If you have ground that you want to look after over winter and make sure it is in great shape in the Spring now is the time to put down the meal. If you have soil with plants in it over winter then i would use the Seafeed. I hope this helps

Seaweed Meal is not really an NPK feed so it is low in NPK. Something like 2/0.5/0.5 as it is more as a soil improver and for boosting the plants system and improving overall growth. For a higher NPK you would be better using the Seafeed mix of meal and organic chicken manure

The NPK of Seaweed meal is almost negligable as it is more a soil improver than a plant tonic. It has a very low NPK

The Seaweed meal is excellent but it sounds more like you need a slow release fertiliser so i would recommend from the same family Seafeed Organic manure pellets which are actually the Seaweed meal mixed with Organic chicken manure in pellet form. This product is applied at a rate of roughly 1 handful per square metre and will wash down gradually through the soil and is excellent for bringing on areas where the soil and plants need a boost
