Seaweed

Seaweed is a wonderful vegetable garden fertilizer, a great soil builder and an excellent compost activator. Seaweed contains complex carbohydrates and these really get the soil humming with life. This has two really important functions for the garden, firstly it stimulates the microbial fungi in the soil and these assist plants in their uptake of nutrients, they also assist in defending plants from soil born diseases. So adding a seaweed fertilizer helps crop protection, and plant nutrition.

It 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.^[2] 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) and amino acids.
