Seaweed for horses
Edwards' Seaweed for healthier pastures and happier horses.

A natural approach to healthier grazing
For centuries, farmers and horse owners along the coast of the UK have recognized the incredible benefits of seaweed for soil health and grazing animals. Now, with modern processing methods, Edwards’ Seaweed Fertilizer makes it easier than ever to harness this natural powerhouse for your pasture - wherever you are.
Why Use Seaweed Fertilizer on Your Grazing Land?
More Nutritious Grass = more Nutritious Hay
Seaweed is packed with essential minerals and antioxidants that naturally enrich the soil, promoting lush, nutrient-dense pasture. Horses benefit from higher-quality forage, reducing the need for additional supplements.


Supports Equine Health
Horses grazing on seaweed-enriched pasture may experience stronger hooves, a shinier coat, and better overall condition thanks to the minerals and antioxidants in seaweed.
​
Safe, Non-Toxic, and Easy to Use
Unlike synthetic fertilizers, Edwards’ Seaweed Fertilizer is completely natural and non-toxic, making it safe for horses, livestock, humans and the environment. Plus, it’s easy to apply via sprayer and integrates seamlessly into your pasture management routine.
Boosts Hay Production – More Bales Per Acre
Healthier, nutrient-rich pastures don’t just benefit grazing horses. Seaweed fertilizer enhances soil fertility and moisture retention, leading to better-quality forage for winter feeding. That means more homegrown nutrition for your horses and potential cost savings on feed.

Edwards' Top Tips for Nutritious Grazing and Soil Management
Healthy soil is the foundation of nutritious pasture for your horse. By managing soil properly with aeration, natural fertilisers, and supporting beneficial bacteria, you can enhance grass quality and ensure a sustainable grazing environment.
​
Aerating Your Paddocks
Roots need space to grow for better nutrient absorption. With horses compacting the soil over time, aeration is essential to reoxygenate and improve structure. Ideally, aerate twice a year, once in autumn to aid recovery before winter and again in late winter/early spring to support early growth.
​
Natural vs. Synthetic Fertilisers
Synthetic fertilisers contain limited nutrients and can lead to unhealthy fluctuations in grass growth. Natural fertilisers, such as seaweed, provide a steady supply of nutrients essential for horse health and may help prevent laminitis. Seaweed enhances the roots depth, improves nutrient and water retention, and supports drought resistance.
​
Why Seaweed is Ideal for Paddocks
Seaweed contains plant hormones, vitamins, and antioxidants that help grass withstand environmental stresses and resist pests. Its nutrients are taken up by the plant within 10 days of application, making it a fast-acting and natural solution. Additionally, it is vegan and safe for horses to ingest, unlike some slurry-based products.
​
Supporting Soil Bacteria
Soil bacteria act as underground nutrient transporters, making nutrients more accessible to plants. They also convert atmospheric nitrogen into a steady supply of plant available nitrogen for growth, preventing the harmful growth spurts caused by synthetic fertilisers. Seaweed fosters a denser pasture with a higher leaf-to-stem ratio, promoting better digestion for horses.
Many landowners have used seaweed fertiliser since the 1960s with great success. Plus, with no withhold period, horses can graze immediately after application, making it a practical and effective choice for pasture management.
