The objective of the study was to determine the market for soil conditioners in one region in order to assist a company processing seaweed to make cost effective use of its residue.

In carrying out the study over 200 contacts were made. The market for seaweed-based products and the prospect of composting of seaweed residue were reviewed.

The contents of the study included:

The European soil conditioner market

Soil amendments on the market in the UK

Seaweed products on the market in the UK

Soil amendments

Seaweed extract and golf courses
