Agricultural biostimulants represent a revolution in modern agriculture, offering a sustainable and effective alternative to improve crop yields. In this comprehensive article, we will explore everything you need to know about these innovative products that are transforming the way we farm.
According to Regulation (EU) 2019/1009, a plant biostimulant is a fertilizer product that stimulates plant nutrition processes independently of the product’s nutrient content, with the sole objective of improving one or more of the following characteristics of the plant or its rhizosphere:
Nutrient use efficiencyIt is essential to understand the differences between these three types of products:
Plant biostimulants offer multiple advantages:
Biostimulants act at the molecular and cellular level, activating specific metabolic pathways:
Hormonal regulation: Modulate the production of endogenous plant hormones such as auxins, cytokinins, and gibberellins
Biostimulants improve the plant’s ability to:
Improve uniformity, quality, and shelf life of fruits and vegetables.
Increase drought tolerance and optimize fertilizer use.
Improve flowering, fruit set, and fruit quality. Increase Brix degrees.
Intensifies greenness, rooting, health, abiotic stress, and dependence on fertilization.
Natural biostimulants for plants are obtained from organic sources and offer high compatibility with sustainable agriculture:
Origin: Decomposition of organic matter
Function: Improve soil structure and nutrient absorption
Application: Fertigation and foliar application
Origin: Hydrolysis of plant or animal proteins
Function: Stimulate metabolism and protein synthesis
Application: Especially effective in stress situations
Seaweed extracts represent one of the most important categories of natural biostimulants:
Origin: Marine algae, although not all algae have the same agronomic value.
Function: Provide natural growth regulators
Application: Foliar and root application, promote rooting and stress resistance
A prominent example in this category is the biostimulant C ystium-a®, a pure extract of brown
algae from the Laminariaceae family developed by Ficosterra. This biostimulant represents the forefront of marine biotechnology applied to agriculture:
Developed using TRD technology (Total Recovery Technology), an exclusive biotechnological system for the total extraction of algae properties never before used in agriculture and awarded a Seal of Excellence by the European Union.
Main species: Glomus, Rhizophagus, Funneliformis
Function: Increase the root absorption surface
Benefits: Improve phosphorus and water absorption
Key species: Bacillus subtilis, Pseudomonas fluorescens, Azotobacter
Function: Fix nitrogen, solubilize phosphorus, produce hormones
Application: Seed inoculation and soil application
Foliar biostimulants are applied directly to the leaves, offering specific advantages:
Longer-lasting effect
To maximize the effectiveness of foliar biostimulants:
Foliar biostimulants are generally compatible with:
Common Incompatibilities:
Products with extreme pH (below 4 or above 9)Key moments to apply biostimulants:
Germination: Improves emergence and initial vigor
Desarrollo vegetativo: Estimula el crecimiento y ramificación
Flowering: Improves fruit set and formation
Ripening: Optimizes quality and preservation
Post-harvest: Facilitates plant recovery
It is always necessary to carefully read the instructions of each manufacturer.
❌ Overdosing: More is not always better
❌ Application under adverse conditions: Avoid extreme temperatures
❌ Incompatible mixtures: Check compatibility before mixing
❌ Incorrect timing: Apply at the appropriate phenological stage
❌ Lack of consistency: Biostimulants require regular applications
Seaweed extracts have become established as one of the most effective biostimulants. The seaweed biostimulant industry is constantly growing due to its multiple benefits:
Innovation in the Sector: TRD Technology
Technological advances have made it possible to develop more efficient seaweed extracts. One example is the TRD technology used in products like Cystium-a®, which allows the extraction of active principles of extraordinary purity and quality from algae of the Laminariaceae family, guaranteeing:
- Greater product stability
- Better bioavailability of active compounds
- More pronounced effects on rooting and apical development
Humic and fulvic acids are fundamental for plant nutrition:
Seaweed extracts have emerged as one of the best options for the development of cutting-edge biostimulants in modern agriculture, standing out for their multifunctional capacity to improve crop growth and resilience. [2]
Fiber and essential macro/microelementsTechnological Innovation:
Macroalgae extracts represent a new generation of sustainable agricultural inputs with multiple simultaneous actions, positioning themselves as key tools for modern agriculture [3].
Biostimulants are fundamental pillars of regenerative agriculture:
Reduce carbon footprint
Application of seaweed extract + amino acids
Program with humic acids + rhizobacteria
Application of foliar biostimulants at veraison
Yes, most biostimulants are compatible with organic farming. Natural biostimulants are allowed under:
Absolutely: Biostimulants are complementary to traditional fertilizers:
The effects vary depending on the type of biostimulant and the application:
Greater resistance to pathogens
Agricultural biostimulants represent the future of a more sustainable, efficient, and productive agriculture. Their integration into fertilization programs allows:
The adoption of biostimulants is not just a trend, but a necessity to face the current challenges of agriculture. Their intelligent and planned use can make the difference between a conventional crop and one that is truly sustainable and profitable.
Are you ready to take the step toward smarter and more sustainable agriculture? Biostimulants are your best ally to achieve it.
