Unicellular Microalgae vs Marine Algae in Biostimulants: Real Differences for Your Crop
The choice of the right biostimulant can determine the success or failure of your crops. The origin of the algae used in a biostimulant is not a minor detail, but a critical characteristic that determines its effectiveness. Most competitors use the brown marine algae Ascophyllum nodosum, while Ecoganic has opted for unicellular microalgae cultivated in photobioreactors. This innovative and controlled approach ensures maximum effectiveness and benefits for plants, elevating the quality of biostimulants to a new level.
What are unicellular microalgae
Unicellular microalgae such as Chlorella vulgaris and Scenedesmus obliquus are photosynthetic organisms that have an exceptionally rich biochemical composition. These microalgae contain 50-70% proteins, chlorophyll, phytohormones such as auxins and cytokinins, polysaccharides, and free amino acids. Their cultivation in photobioreactors allows total control over growth conditions, ensuring a standardized and high-quality product.
What is Ascophyllum nodosum
Ascophyllum nodosum is a brown marine algae widely used in biostimulants due to its content of alginates, laminarin, and phytohormones. Traditional extraction methods, which include heat, cold, and solvents, can affect the concentration of its active components. Additionally, its composition can vary seasonally, impacting the consistency of the final product.
Technical comparison table
| Criterion | Unicellular Microalgae | Ascophyllum nodosum |
|---|---|---|
| Origin | Photobioreactor | Marine collection |
| Cultivation/extraction method | Controlled | Heat, cold, solvents |
| Composition variability | Minimal | High |
| Phytohormone content | Auxins, cytokinins | Betaine, auxins |
| Bioavailability | High | Moderate |
| Soil impact | Improves structure | Variable |
| Traceability | High | Low |
| Organic certification | Yes | Not guaranteed |
| Environmental sustainability | High | Moderate |
| Effect on root vs aerial part | Balanced | Variable |
Why traceability matters
Traceability in the production of biostimulants is essential to ensure the quality and effectiveness of the product. Using microalgae cultivated in photobioreactors allows precise control of each batch, guaranteeing consistency and purity. In contrast, marine collection presents challenges in consistency and quality due to environmental factors and seasonal variability.
Comparative studies
Studies have shown that unicellular microalgae are more effective in root stimulation and improving drought tolerance compared to Ascophyllum nodosum. Crops treated with microalgae also show a significant improvement in fruit quality, reflected in size, coloration, and nutritional content.
Which crops respond best to each type
Crops such as avocado, vine, and olive respond optimally to biostimulants of unicellular microalgae due to their balanced biochemical composition. On the other hand, citrus, tomato, cocoa, and coffee can benefit from both microalgae and Ascophyllum nodosum, depending on the specific needs of each growth phase.
Conclusion
Unicellular microalgae represent the future of agricultural biostimulants. Their controlled cultivation and rich composition in critical nutrients provide a more effective and sustainable solution to the current challenges in agronomy. Ecoganic positions itself at the forefront of this innovation by offering high-quality products with unparalleled consistency.
FAQ
