A New Generation of Seaweed Products

Designed for Abiotic Stress Defence 

For the future of Modern farming

Our pure, high-quality seaweed extract is a powerful, natural biostimulant designed to optimise crop growth and resilience in agriculture and horticulture. Rich in bioactive compounds, it enhances nutrient uptake, boosts root and shoot development, and improves plant tolerance to environmental stresses like drought and pests. Ideal for foliar spraying or soil application, this extract supports healthier, more robust crops without synthetic additives. Sustainably sourced and carefully crafted to retain maximum potency, it promotes plant growth and superior crop quality, making it an essential tool for farmers and growers seeking higher yields and more resilient plants with an eco-friendly approach.

The Crop Smith core products are CS1 & SW1 produced from Ascophyllum nodosum (knotted wrack) seaweed harvested from the clean North Atlantic shores of the UK.

These can be provided in high volumes at wholesale prices for blending and white label sales.

We have a range of blended CS & SW products for bespoke applications on different crops.

Our premium seaweed meal is a natural soil amendment designed to enrich agricultural and horticultural soils with essential nutrients and bioactive compounds. Rich in trace minerals, amino acids, and natural growth hormones, it supports robust root development, improves soil structure, and boosts plants’ resilience to environmental stress. Ideal for mixing into soil or compost, this seaweed meal enhances microbial activity and nutrient availability, promoting healthier, more productive plants. Sustainably sourced and free from synthetic additives, it is an eco-friendly choice for those aiming to increase yield and quality and to foster sustainable soil health.

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 a valuable component of crop cultivation, but is not the whole story.

Harvesting

&

Processing

Grown wild in the clean North Atlantic ocean, on the shores of the UK & Ireland, Ascophyllum nodosum has been hand harvested for generations by the local community. It is processed and dried locally,  providing a sustainable industry and support for local communities.

Science

&

Quality

The Crop Smith Ltd. is continually running trials on different crops to establish robust data illustrating where the benefits of seaweed products are. Knowing how a product should be applied, and what to expect, is as important as the contents of the product itself.
