Introduction

In the current agricultural context, biological fertilizers for corn are emerging as a viable and sustainable alternative to traditional chemical inputs. In Argentina, where corn production is crucial for the economy, understanding the advantages of these products is essential for improving crop yield and sustainability. This article will explore the advantages of biological fertilizers, their certification by SENASA, and how they can transform agriculture in our country.

Advantages of Biological Fertilizers

Biological fertilizers offer multiple benefits compared to chemical products. Some of the main advantages include:

• Improvement of soil health: Biological fertilizers promote microbial activity in the soil, improving its structure and fertility. This is essential for corn growth, as healthy soil retains moisture and nutrients better.
• Reduction of dependence on chemical inputs: By using biological fertilizers, farmers can decrease the amount of chemical fertilizers needed, resulting in lower operating costs and reduced environmental impact.
• Improvement of crop yield: Studies have shown that biological fertilizers can increase corn yield, enhancing both quality and quantity of production.
• Lower risk of contamination: Unlike chemical fertilizers, biological ones have a lower risk of negatively affecting groundwater and local biodiversity.

Mechanisms of Action of Biological Fertilizers

Biological fertilizers act through various mechanisms that enhance nutrient availability for plants. These mechanisms include:

• Biological nitrogen fixation: Some bacteria like Rhizobium and Azospirillum can fix atmospheric nitrogen, converting it into forms that plants can assimilate. This is particularly relevant in corn cultivation, where nitrogen demand is high. It is estimated that 60% of the nitrogen required by corn can be supplied through biological fixation.
• Phosphorus solubilization: Microorganisms such as Mycorrhizae and certain soil bacteria help solubilize phosphorus, a critical nutrient for root development and corn flowering. One study demonstrated that the use of mycorrhizal inoculants increased phosphorus availability by 40% in low-fertility soils.
• Production of phytohormones: Some microorganisms promote plant growth by producing hormones like auxins and cytokinins, which stimulate root and shoot growth. This results in a more robust root system, allowing plants to absorb more nutrients and water.
• Competition with pathogens: Biological fertilizers can also help protect plants from diseases by competing with pathogens for space and resources. For example, certain strains of Bacillus have been shown to be effective in suppressing phytopathogenic fungi in the soil.

Practical Application Examples in the Field

In practice, the application of biological fertilizers has shown promising results. For example, in a study conducted in the province of Córdoba, biological inoculants were applied to corn crops, resulting in a 20% increase in yield compared to crops that only received chemical fertilizers. Additionally, farmers reported improvements in grain quality and disease resistance. Another example is the use of compost-based fertilizers, which not only provide nutrients but also improve soil structure, increasing its capacity to retain water and nutrients.

Another successful case occurred in the province of Buenos Aires, where a group of farmers implemented a biological fertilization program in their corn crops. By using a combination of nitrogen-fixing bacteria and mycorrhizal fungi, they achieved an average yield increase of 25% compared to the previous year, when only chemical fertilizers were used. This increase was accompanied by greater drought resistance, resulting in a more stable and profitable harvest.

Case Studies in Different Regions

In the Entre Ríos region, a study conducted in 2021 analyzed the impact of applying biological fertilizers in corn crops. In this case, an inoculant containing Azospirillum brasilense was used, resulting in a 30% increase in corn yield compared to the control. Researchers also noted that the use of this inoculant improved water use efficiency, which is crucial in drought years.

Another significant example comes from the Santa Fe area, where a biological fertilization program was implemented in an agricultural cooperative. An integrated approach was used that included crop rotation and the application of biological fertilizers. As a result, farmers reported a 15% increase in corn production and a 40% reduction in the use of chemical fertilizers, demonstrating the economic and environmental viability of this practice.
