DONEGAL SEAWEED LIMITED

Donegal Seaweed Limited is a family‑run Irish company that produces premium, organic liquid seaweed biofertilisers from hand‑harvested *Ascophyllum nodosum* collected in the Atlantic’s clean waters. By adhering to traditional, low‑impact harvesting techniques and a strict rotation policy, the business safeguards marine ecosystems while delivering a nutrient‑rich, fully chelated product that is immediately available to plants.

Their range is tailored for three key markets: sporting surfaces such as golf courses, where the extracts improve soil structure, porosity and water‑holding capacity; commercial growers, with formulations enriched in magnesium, potassium, zinc and iron that boost yields of potatoes, sweet corn, tomatoes, strawberries and more; and domestic gardeners, who benefit from a complete suite of micro‑nutrients and carbohydrates that enhance germination, root development and overall plant vigour. All products are 100 % organic, supporting sustainable agriculture and robust plant defence against pests and disease.

Donegal Seaweed’s biofertilisers are aimed at eco‑conscious farmers, horticulturists and garden enthusiasts who seek effective, environmentally friendly nutrition for their crops and landscapes.
