Biofertilizers, an efficient, sustainable solution against the nitrate pollution

noviembre 14, 2023

For over 20 years, Probelte has been developing new technologies based on agro-biotechnological agents, sustainable alternatives that are essential for their part in integrated production, ecological agriculture, the need to produce healthy food and the environmental emergency.


Under the motto “From Soil to Health”, Probelte’s strategy stems from its commitment to caring for the health of the field with its comprehensive solutions, biofertilizers and biocontrol products, which combine preventive and palliative strategies supported by digital tools. Probelte is already present in more than 50 countries and continues its global expansion with value agreements and collaborations with the largest international players in the bio-agro sector. Today it is a consolidated company that continues to look to the future, reinforcing its effort, dedication, experience, and vocation from the inside out to be the company where well-being is born.


With more than 50 years of experience in the phytosanitary and plant nutrition sector, Probelte is at the forefront of the most modern agrobiotechnological production. Since 1997, more than 90 different microorganisms have passed through the hands of its researchers. As a result, they have developed dozens of state-of-the-art biological solutions for crop protection, plant health and, ultimately, people’s health.

Nitrate pollution, an issue that needs to be addressed

A significant portion of nitrogen added in the form of nitrates and nitrites is immobilized due to the action of other microorganisms present in the substrate, through association with soil particles or leaching. Excessive nitrogen pollution affects fields and water, causing particularly severe problems in certain production areas.

Biofertilizers – by preventing leaching, among others – are respectful and valuable tools for compliance with the Agriculture Discharge Order, the Sustainable Groundwater Management Act (SGMA), and the premises set forth in water code section 10750 of California.

Bulhnova and Komens, state-of-the-art biofertilizers

Although there are many bacteria capable of acting as biofertilizers, agrobiotechnological products like Komens and Bulhnova from Probelte have more than a decade of development and selection of the best strains and technology behind them to maximize their efficiency. Two strains of the species Pantoea dispersa and Azospirillum brasilense have been identified and isolated through biotechnology to provide the best results in the field:

  • They are highly effective. Field research demonstrates that they can completely replace traditional fertilizers while maintaining the same production levels.
  • They are clean. As there is no excess of nitrates, they do not have a negative impact.
  • They are certified for organic agriculture.

Bulhnova and Komens are cutting-edge biofertilizers, effective tools designed for modern and sustainable agriculture. With their application, farmers can continue production even in areas where nitrogen fertilizers are prohibited due to their potential for contamination.
