The Crop Smith provides industry with a core range of seaweed products for branded or white label distribution
CS Liquid Products
CS1 is produced from UK hand harvested Ascophyllum nodosum. It is made using an extended, multi-stage, aqueous extraction process. It has a low a pH of between 4.5 & 4.8 and is ideal for blending and tank mixing. It is higher in bioactive compounds than most of the leading seaweed extract brands. Supplied in bulk at the most affordable rates in the market, CS1 is a high-quality, easy-to-use product. It comes with internal & external trial data for buyer confidence.
SW Granular Products
SW1 is our core granulated product. It is a sustainable and renewable resource. Its use as a soil conditioner promotes eco-friendly cultivation practices and can reduce reliance on synthetic fertilisers and chemicals. The increase in organic matter improves soil structure and fertility, promoting mycorrhizal activity. The increase in mycorrhizal fungal activity in the soil promotes early root growth and supports a healthy root system giving the crops a better start especially under harsh conditions.

Why Seaweed?
Seaweed in horticulture is not a new phenomenon. It has been used as a soil improver in crop cultivation for millennia. Modern agronomy has been dominated by chemistry based product development which is valuable but, is not the full story.
