Acadian delivers consistent, reliable performance by offering three critical advantages that transform your ROI

Powerful

Acadian enhances plant resilience and productivity by strengthening stress tolerance, boosting nutrient uptake, and building a stronger root system. It increases chlorophyll, photosynthesis, and vigor, driving improved growth and ultimately higher fruit number and weight—even under challenging conditions.

Versatile

Acadian integrates easily into any program with broad tank‑mix compatibility, supports soil health and microbial activity, and offers a sustainable solution for both conventional and organic systems.

Consistent

Acadian delivers reliable performance through a pure Ascophyllum nodosum extract and a proprietary alkaline process that ensures more active compounds, full solubility, and stable 3+ year shelf life without settling or clogging.

Strawberries

Problem - Solution Fit

Problem Faced	Solution / Benefit	Why It Matters
Poor Seedling Vigor	Boosts root development & early growth	Faster establishment; stronger plants
Nutrient deficiency	Improved nutrient uptake & use via natural chelators and bigger root system	Ensures plants have nutrients for optimal growth; reduces deficiencies that prevent or stunt growth; promotes healthier plants
Salinity stress	Increased water use efficiency & root development. Reduces damage from sodium and chloride	Minimizes stress during drought and saline soils
Low fruit set	Stimulates flowering and fruit set	Increases yield potential
Poor quality fruit	Enhances nutrient uptake and use, boosts Brix	Elevates yield & fruit quality

Proven Marketable Yield Advantage

Recent California field trials showed that Acadian at 32 oz/acre consistently matches or outperforms competing seaweed products applied at 64 oz/acre. Across trials, Acadian delivered higher marketable yields, boosting production by 24.1% over the control, compared with 15.6% from competing treatments. These results demonstrate that Acadian, at the lower 32 oz/acre rate, provides strawberry growers with a stronger, more reliable increase in productivity per acre.

Wine Grapes

Problem - Solution Fit

Problem Faced	Solution / Benefit	Why It Matters
Drought	Improves root growth and water use efficiency	Maintains wine grape vine function and grape development under dry conditions
Low fruit set / flower drop	Supports reproductive energy and fruit initiation	Increases yield potential and improves cluster uniformity
Heat stress	Antioxidants support heat tolerance	Reduces berry damage and helps maintain fruit quality
Uneven ripening	Supports balanced sugar and nutrient uptake	Promotes uniform ripening across the cluster
Compact clusters / disease risk	Improves canopy strength and airflow	Reduces disease pressure by enhancing ventilation
Post-harvest	Replenishes reserves and supports root health	Helps wine grape vines recover and prepare for next season (fall root flush)

Proven Marketable Yield Advantage

Six independent field trials in California (Lodi – Chardonnay; Kingsburg – French Colombard) evaluated Acadian at 32 oz/acre versus untreated control and a seaweed competitor at 64 oz/acre. Measured indicators included leaf area index, rachis length/cluster compactness, canopy performance under heat/salinity, berry °Brix distribution, and marketable yield.

Across trials, Acadian increased marketable yield by 34.4% vs. control (competitor: 20.3%) and improved canopy and fruit indicators associated with cluster quality and ripening uniformity. Full protocols and raw data available on request.

Table Grapes

Problem - Solution Fit

Problem Faced	Solution / Benefit	Why It Matters
Drought (Water Stress)	Improves root growth and water use efficiency	Maintains table grape vine function and fruit development under dry conditions
Low fruit set / flower drop	Supports reproductive energy and fruit initiation	Increases yield potential and improves cluster uniformity
Heat stress	Antioxidants support heat tolerance	Reduces berry damage and helps maintain fruit quality
Uneven ripening	Supports balanced sugar and nutrient uptake	Promotes uniform ripening across the cluster
Compact clusters / disease risk	Improves canopy strength and airflow	Reduces disease pressure by enhancing ventilation
Post-harvest	Replenishes reserves and supports root health	Helps table grape vines recover and prepare for next season (fall root flush)

Proven Marketable Yield Advantage

Independent field trials conducted in Terra Bella (Allison) and Ducor (Krissy), California, showed that Acadian at 32 oz/acre consistently matches or outperforms competing seaweed products applied at 64 oz/acre. Across trials, Acadian delivered higher marketable yields—boosting production by 28.4% over the control, compared with 11.7% from competing treatments.

These results demonstrate that Acadian at 32 oz/acre provides table grape growers with a stronger, more reliable increase in productivity per acre.

Almonds

Problem - Solution Fit

Problem Faced	Solution / Benefit	Why It Matters
Poor pollination & low nut set	Improves flower development and supports reproductive processes	Leads to better fruit set and higher yield potential
Nutrient deficiency	Acts as a natural chelator to enhance nutrient availability	Promotes healthy tree growth and optimal nut development
Low fruit quality (size/flavor)	Enhances nutrient metabolism and strengthens cell-wall integrity	Produces larger, firmer almonds and improves marketability
Water stress	Increases water use efficiency and supports root function	Helps trees maintain performance under limited irrigation and osmotic stress
Heat stress	Boosts heat tolerance and overall stress resilience	Protects flowering and fruit set, helping maintain yield and nut quality under high temperatures

Proven Marketable Yield Advantage

Recent independent field trials conducted in Arbuckle and Terra Bella, California showed that Acadian at 32 oz/acre consistently matches or outperforms competing seaweed products applied at 64 oz/acre.

Across trials, Acadian delivered higher marketable yields, boosting production by 8.7% over the control compared with 5.3% from competing treatments. These results demonstrate that Acadian at 32 oz/acre provides almond growers with a stronger, more reliable increase in productivity per acre.

Acadian increased total pounds per acre by 8.7%. Based on average market prices at the time of picking ($2.40 per pound), this translated into an additional US$492 in gross revenue per acre.
