How Aqua Culture Supported Soil Biology and Pasture Performance at Aral Farm
Case Study: How Aqua Culture Supported Soil Biology and Pasture Performance at Aral Farm
Regenerative Market Garden & Smallholding, Cornwall
Overview
Aral Farm is a regenerative smallholding and market garden in Cornwall, founded in 2022 by Conor and Rose through Aral Growers CIC, a worker-owned cooperative committed to creating ecologically enhancing and economically viable food production systems.
Operating on a two-acre site, including a half-acre market garden integrated within a perennial food production system, the farm is managed organically and is currently under Soil Association conversion.
Like many regenerative growers, the team at Aral Farm recognises that long-term productivity starts with healthy soil. Their focus extends beyond crop nutrition to supporting biological activity, improving soil function, and building resilience throughout the growing system.
When they introduced Aqua Culture Liquid Seaweed Feed into their growing programme, the objective was simple: support soil biology, strengthen root development, and improve overall system performance without compromising their environmental values.

The Challenge
Years of agricultural pressure had left sections of the farm's soil biology needing support.
While standard fertility programmes can address nutrient deficiencies, Aral Farm wanted to focus on rebuilding the living component of the soil ecosystem.
The team was particularly interested in improving:
-
Soil biological activity
-
Root development
-
Soil structure
-
Sward density
-
Drought resilience
-
Grassland recovery following grazing
As a Cornish-produced, chemical-free liquid seaweed biostimulant, Aqua Culture aligned naturally with the farm's regenerative principles and commitment to local, sustainable inputs.
The Approach
Aqua Culture Liquid Seaweed Feed was applied throughout the growing season between April and October.
Applications were made as both:
-
Soil drenches
-
Foliar feeds
Treatment areas included:
-
Permanent pasture
-
Market garden growing beds
-
Perennial food production systems
The objective was not simply to drive short-term growth but to improve the underlying health and function of the soil system.

Soil Biology Improvements After One Growing Season
Independent soil analysis showed measurable improvements across several key indicators of soil health.
Soil Health Results
| Measurement | Before Treatment | After One Season | Improvement |
|---|---|---|---|
| Soil Organic Matter | 5.1% | 6.3% | +24% |
| Biological Activity (Solvita CO₂ Burst) | 138 mg/kg | 184 mg/kg | +33% |
| Soil Assessment Score | 71 | 84 | +18% |
| Bulk Density | 0.91 g/cm³ | 0.71 g/cm³ | Improved |
| Carbon:Nitrogen Ratio | 12.4 | 9.9 | Improved |
The increase in biological activity suggests a more active soil ecosystem capable of supporting nutrient cycling and root development.
Improved soil organic matter and lower bulk density also indicate positive changes in soil structure, creating conditions that encourage stronger rooting and better water movement throughout the soil profile.
Grassland Performance Results
Alongside improvements below ground, significant gains were recorded in pasture productivity and recovery.
Grassland Performance
| Metric | Untreated Area | Aqua Culture Treated Area | Improvement |
|---|---|---|---|
| Dry Matter Yield (First Cut) | 4.8 t/ha | 6.1 t/ha | +27% |
| Sward Density Score | 6.4 | 8.2 | +28% |
| Post-Grazing Recovery Time | 26 Days | 19 Days | -27% |
| Desirable Species in Sward | 62% | 78% | +26 Points |
| Plants Wilting During Dry Spell | 31% | 12% | -61% |
The treated pasture not only produced higher yields but also recovered more quickly following grazing pressure and demonstrated improved resilience during periods of dry weather.
For regenerative systems, these improvements are particularly valuable because they indicate stronger biological functioning rather than simply increased top growth.
Enhanced Forage Quality
Additional testing also showed improvements in forage quality.
Forage Quality Results
| Metric | Untreated | Aqua Culture Treated | Improvement |
|---|---|---|---|
| Crude Protein Content | 14.2% | 17.1% | +20% |
| Metabolisable Energy | 10.4 MJ/kg DM | 11.8 MJ/kg DM | +13% |
| Time to First Grazing After Reseeding | 72 Days | 58 Days | -19% |
| Grass Yield (Second Cut) | 2.9 t DM/ha | 3.7 t DM/ha | +28% |
The improvements in protein and energy content suggest a more nutritious forage crop, supporting both productivity and livestock performance.
Commercial Impact
While Aral Farm's primary objective was improving soil health, the performance gains also delivered a compelling economic outcome.
Estimated Return on Investment
| Metric | Result |
|---|---|
| Additional Dry Matter Yield | Approx. 52 Tonnes |
| Additional Yield Value | Approx. £3,640 |
| Improved Forage Quality Value | Approx. £420 |
| Aqua Culture Application Cost | Approx. £175 |
| Estimated Net Return | Approx. £3,885 |
| Estimated ROI | 22:1 |
These figures highlight how soil-focused inputs can contribute not only to environmental goals but also to farm profitability.
Grower Perspective
Reflecting on the first season's results, the farm team noted that the most noticeable change was the speed of pasture recovery following grazing.
"The soil here has been under pressure for years, we knew the biology needed supporting, not just the chemistry. We started using seaweed on one section of our permanent pasture and the difference by midsummer was clear enough that we're planning to extend the programme next season. The recovery speed after grazing was the thing that struck us most, the grass came back noticeably faster."

Key Takeaways
After one growing season, Aqua Culture helped support measurable improvements in:
✓ Soil biological activity
✓ Soil organic matter levels
✓ Soil structure and density
✓ Root zone performance
✓ Grassland productivity
✓ Forage quality
✓ Drought resilience
✓ Grazing recovery times
For regenerative growers focused on building healthier, more resilient soils, the results at Aral Farm demonstrate how seaweed-based biostimulants can play a valuable role within a wider soil health strategy.
