Seaweed fertiliser

Seaweed fertiliser


Seaweed fertilizer, also spelt seaweed fertiliser, is a valuable addition to the organic garden, and is abundantly available for free for those living near the coast. However, caution should be observed when collecting seaweed, particularly from areas that are liable to pollution, such as downriver (including estuaries) of industrial activities as seaweed is susceptible to contamination.

A perhaps less serious potential problem with seaweed is its salt content. While it is unlikely that you will add sufficient seaweed to seriously upset the balances of salt in your soil, it is not liked by worms, who will not live in it. It can be hosed down before adding to the soil to reduce the salt content, or left to be desalinated by rainwater.

Seaweed, particularly bladderwrack, kelp or laminaria, can be either applied to the soil as a mulch (although it will tend to break down very quickly) or can be added to the compost heap, where it is an excellent activator. In terms of soil structure it does not add a great deal of bulk, but its jelly like alginate content helps to bind soil crumbs together, and it contains all soil nutrients (0.3% N, 0.1% P, 1.0% K, plus a full range of trace elements). For those who cannot gather fresh seaweed, it is available commercially in a dried 'meal' form, which can be applied at a rate of 60-100g per square metre, or as a concentrated liquid feed which should be diluted @ 1 part to 15 with water, and can be applied either as a foliar feed or to the root zone.

In the Channel Islands, such seaweed fertiliser is known as "vraic" in their dialects of Norman, a word that has also entered Channel Island English, the activity of collecting vraic being termed "vraicking". In Scotland, it is used as fertiliser in lazybeds or "feannagan".

Falkland Islanders have also been nicknamed "Kelpers" from time to time, from collecting seaweed partly for this purpose.
