The Power of Combining Biofertilizers and Biostimulants
The combination of biofertilizers and biostimulants is a key strategy for boosting crop development by optimizing nutrition, root growth, and overall yield. A trial conducted in Rafelbuñol, Valencia, on Marisol mandarin evaluated the effects of applying Bulhnova together with Spirunol versus a conventional fertilizer. The results highlight the synergistic benefits of both products and reinforce the importance of integrating complementary solutions to maximize efficiency in microbial-based agronomic management.
Evidence of the Synergy Between Bulhnova and Spirunol
The data collected shows that the combination of Bulhnova and Spirunol resulted in a 9% increase in fruit size. This effect can be attributed to the combined action of both products:
- Bulhnova enhances nutrient availability in the soil, fixes atmospheric nitrogen, and stimulates beneficial microbiota.
- Spirunol promotes root development and helps beneficial microorganisms thrive efficiently.
Regarding average fruit weight, the Bulhnova + Spirunol treatment achieved 130g per fruit, outperforming the conventional fertilizer treatment. When comparing Bulhnova + Spirunol with mineral fertilization, the results consistently showed improvements while also implementing a more sustainable mid- to long-term approach.
Additionally, these findings suggest that the positive synergy between both products supports more uniform fruit development. Meanwhile, Brix levels remained consistent across both treatments, averaging 9.2° Brix, ensuring that fruit quality meets commercial standards.
How Do Bulhnova and Spirunol Work Together in Plants?
The synergy between Bulhnova and Spirunol is explained by their complementary modes of action:
- Bulhnova, formulated with two beneficial bacterial strains, improves soil fertility and optimizes the availability of key nutrients such as nitrogen, phosphorus, and potassium. This is essential for balanced plant growth and a continuous supply of essential elements for fruit development.
- Spirunol, a powerful biostimulant derived from the enzymatic hydrolysis of microalgae, promotes root growth and metabolic activity in plants. It provides key elements that support Bulhnova’s bacterial activity, stimulating the production of phytohormones like auxins and cytokinins. These hormones are crucial for cell division and fruit expansion, which explains the increase in fruit size observed in the trial.
Furthermore, by reinforcing root structure, Spirunol enhances nutrient uptake from Bulhnova-released nutrients, maximizing efficiency and promoting stronger plant growth.
The greater root development induced by Spirunol also improves crop resilience against abiotic stress. This enhanced root system facilitates the uptake of calcium and potassium, two essential elements for fruit firmness, sugar accumulation, and fatty acid composition, all of which directly impact fruit quality.
Trial Methodology and Application Protocol
The trial was conducted on a farm in the Valencian Community, using a fertigation system and a loam-clay soil structure. The demonstration area covered 2.3 hectares, with the field divided into two treatment strategies:
1️⃣ Conventional Fertilization Treatment:
- Soil applications at 5 L/ha, applied monthly from March onwards.
2️⃣ Bulhnova + Spirunol Treatment:
- Bulhnova (5 L/ha, root application) + Spirunol (5 L/ha, foliar & root application).
Benefits of Combining Biofertilization and Biostimulation
The results of this trial demonstrate that integrating biofertilization and biostimulation improves both sustainability and productivity in mandarin cultivation. This combination not only enhances plant nutrition but also positively impacts growth uniformity and fruit quality.
Seeking synergies between products like Bulhnova and Spirunol allows for the development of more efficient crop management programs, tailored to specific agronomic needs. The findings from this Marisol mandarin trial pave the way for further research in other crops where the interaction between biofertilization and biostimulation can drive significant improvements in profitability.
