Liquid Seaweed Biostimulant Trials

In 2025, HighVantage collaborated with Câr-y-Môr as part of an innovative programme exploring the potential of their liquid seaweed biostimulant in modern farming systems.

With increasing pressure on growers to reduce synthetic inputs while maintaining productivity, this trial set out to evaluate how natural, sustainable alternatives can support crop performance across a range of environments.

Trial Overview

The trials were conducted over two years, spanning six farms and covering both conventional and organic systems. A diverse range of crops were included to assess broad applicability, including:

• Cereals
• Potatoes
• Grassland

Across the programme:

• 6 hectares were treated
• 3 different application methods were tested

This approach allowed for a comprehensive assessment of how seaweed-based biostimulants perform under real-world farming conditions.

The Role of Drone Application

A key part of the trial was exploring how precision drone application can enhance the effectiveness of biostimulants.

HighVantage’s drone services provided:

• Accurate and even coverage
• Reduced soil compaction
• Minimal disruption to crops
• Efficient application across varied terrain

This method complements Câr-y-Môr’s seaweed product perfectly—ensuring it is delivered exactly where and when it’s needed.

A Sustainable Solution for Modern Farming

As the agricultural industry moves toward reducing reliance on synthetic fertilisers, biostimulants like liquid seaweed are becoming increasingly important.

This collaboration highlights a powerful combination:

• A sustainable, naturally derived product
• Applied using low-impact, precision technology

Together, they offer a practical pathway for farmers to improve resilience, maintain yields, and meet the growing demand for more sustainable food production.

Looking Ahead

The results from these trials reinforce the role that innovation and collaboration will play in the future of agriculture.

By combining marine-based resources with cutting-edge drone technology, HighVantage and Câr-y-Môr are opening up the possibility of a more sustainable and efficient farming landscape—one that works with nature, not against it.
