Biological fertilizers act through various biochemical mechanisms that favor plant growth. For example, some microorganisms present in these fertilizers can solubilize nutrients from the soil, making them more accessible to plants. A study published in the journal Soil Biology and Biochemistry demonstrated that certain bacteria of the genus Azospirillum can increase the availability of phosphorus in the soil by 40%, thus improving plant nutrition. Additionally, some mycorrhizal fungi associated with plant roots can increase the absorption of water and nutrients, improving resistance to water stress conditions. This process is known as symbiosis, where the fungus provides essential nutrients to the plant in exchange for carbohydrates.

Additional Benefits of Biological Fertilizers

Biological fertilizers not only provide nutrients but can also induce defense responses in plants. For example, the application of certain bio-stimulants can increase the production of secondary metabolites, which are compounds that help plants defend against pests and diseases. A study from the National University of Córdoba found that the use of seaweed extracts not only improved growth but also reduced pest incidence by 20% in pepper crops. Furthermore, the activation of these defenses can result in greater resistance to adverse conditions, such as drought or saline soils.

SENASA Certification in Argentina

SENASA certification is a crucial process for biological fertilizers in Argentina. This agency regulates and ensures that products meet quality and safety standards. To obtain this certification, producers must follow certain steps:

• Product Registration: All biological fertilizers must be registered with SENASA, where their components and properties are evaluated. This process includes reviewing the chemical composition and identifying microorganisms present in the product.
• Efficacy Testing: Products must demonstrate their efficacy through scientific tests and field trials. This involves conducting comparative studies that show the performance of crops treated with biological fertilizers against those treated with chemical fertilizers.
• Risk Assessment: Risk studies must be conducted to ensure that there are no adverse effects on human or environmental health. This includes evaluating the impact of products on biodiversity and the possible transfer of genes between microorganisms.
