5 Top Biological Innovations Boost Soybean Yields in Brazil

Discover how breakthroughs in biological soil treatments revolutionize soybean production in Brazil,
naturally increasing crop yield and reducing reliance on chemical fertilizers.

“Brazilian farmers using biological soil treatments saw soybean yields increase by up to 20% in recent studies.”

Introduction: The Rapid Growth of Brazilian Agriculture and Soybean Production

Brazil has long been recognized as a world leader in agricultural innovation, standing out as the top producer and exporter of soybeans. The growth of Brazilian agriculture over the last four decades is nothing less than spectacular; especially notable is soybean production in Brazil, which skyrocketed from 15 million metric tons in the 1980s to over 170 million tons today. This incredible transformation was made possible by a combination of visionary research, cutting-edge technology, and a steadfast commitment to sustainable farming solutions.

At the heart of this green revolution are biological soil treatments—innovations that harness naturally occurring bacteria and microbes to enrich soil nutrients and promote healthy crop growth. These biological products for farming have not only increased crop yield naturally but also helped Brazilian farmers reduce their reliance on commercial chemical fertilizers, decrease production costs, and meet the rising demand from environmentally-conscious consumers for food produced with fewer chemicals.

In this post, we take a closer look at the top five biological innovations driving this revolution, with a particular focus on contributions by renowned Brazilian microbiologist Mariangela Hungria, recipient of the 2025 World Food Prize. We’ll explore how new soil treatments are transforming not only Brazil, but also the global landscape for sustainable soybean agriculture.

Context: Hungria’s Work and the Boom in Soybean Production in Brazil

In 2025, the World Food Prize was awarded to Dr. Mariangela Hungria, a Brazilian microbiologist whose research transformed both the scale and sustainability of soybean production in Brazil. Her pioneering work at Embrapa, Brazil’s leading state-run agricultural center, focused on improving how plants acquire nutrients—particularly through the isolated use of soil bacteria and biological treatments.

Traditionally, soybeans need large inputs of nitrogen to grow robustly. Importing nitrogen-based chemical fertilizers was expensive and left the country heavily dependent on global suppliers. Recognizing this challenge, Hungria isolated potent rhizobia strains, enabling inoculation of soybean seeds with beneficial bacteria that fix nitrogen directly from the atmosphere. The results were revolutionary for Brazilian farmers—a solution both widespread and highly effective, now applied on more than 40 million hectares of Brazilian soybean plantations.

Let us now explore how these innovations—alongside others—are reshaping the landscape for producer nations, exporters, and consumers alike, fulfilling demand for high-yield, low-chemical-sourced food commodities.

5 Top Biological Innovations Boosting Soybean Yields in Brazil

1. Rhizobium Inoculants for Nitrogen Fixation in Agriculture

One of the most transformative innovations in Brazilian soybean production is the use of rhizobia bacteria inoculants. Rhizobia are soil bacteria that enter into a symbiotic relationship with soybean root nodules, enabling the plant to fix atmospheric nitrogen—a process vital for healthy, robust plant growth. By inoculating soybean seeds with these isolated strains before planting, Brazilian farmers have greatly enhanced the natural fertility of their fields.

• Nitrogen fixation in agriculture: This approach reduces or eliminates the need for imported synthetic nitrogen fertilizers, thereby decreasing costs and dependency on foreign sources.
• Increased yield: Fields using rhizobia inoculants have observed yield improvements of up to 20% compared to non-inoculated plots.
• Widespread solution: Today, this practice is used across more than 40 million hectares of Brazilian soybean plantations.

This innovation is attributed directly to Dr. Hungria’s research at Embrapa, highlighting the profound, lasting impact scientific discovery has on commercial agriculture.

2. Azospirillum brasilense: Boosting Root Systems for Larger Yields

The next breakthrough leverages another native bacteria—Azospirillum brasilense. While rhizobia primarily assist with nitrogen, Azospirillum offers a suite of benefits to both soybeans and other crops like corn:

• Bigger roots: Azospirillum brasilense stimulates the development of larger and deeper root systems, enabling plants to access water and nutrients even during periods of low soil humidity.
• Resilience: Crops inoculated with Azospirillum demonstrate enhanced drought resistance, essential for production in Brazil’s Cerrado and other challenging climates.
• Legume synergy: When used in combination with rhizobia, these strains create a synergistic effect that further improves plant growth and overall production.

Such innovations, when implemented en masse, contribute significant yield gains and support the sustainable intensification of agriculture across the country.

“Biological innovations have reduced chemical fertilizer use in Brazilian soybean fields by approximately 30% since 2020.”

3. Microbial Consortia: Synergistic Soil Health Builders

Another remarkable stride has been made with the development and application of microbial consortia—blends of multiple bacteria and fungi specifically designed to improve soil health and plant growth. These innovative products deliver broad benefits:

• Enhanced nutrient uptake: Multispecies blends catalyze critical nutrient cycles, making phosphorus, potassium, and trace elements more available.
• Greater biological resilience: Diverse strains provide robust defense against a wider range of soil-borne diseases and pests.
• Sustainable yield increase: Trials in Brazil have shown yield boosts of 8-15% using these biological soil treatments.

Microbial consortia serve as potent sustainable farming solutions and mark the industry’s future, as more producers in Brazil and worldwide shift to biological products for farming.

4. Biostimulants and Biofertilizers: Natural Plant Growth Promoters

Brazil is at the forefront in the use of biostimulants and biofertilizers as alternatives to traditional chemical fertilizers. These natural compounds and living organisms work in a variety of complementary ways:

• Stimulating root and shoot growth: By naturally enhancing metabolic processes, plants grow larger and more resilient.
• Improved stress tolerance: Plants treated with biostimulants can withstand environmental stressors such as drought and nutrient-poor soils.
• Reduced chemical fertilizer usage: Some regions have reported up to 30% reductions in synthetic fertilizer dependency thanks to biostimulant applications.
• Boosted yields: Field results show average yield increase of 6-12%.

As consumers increasingly demand food produced with fewer chemicals, these sustainable tools are becoming vital for the future of Brazilian agriculture.

5. Biological Control of Soil-Borne Diseases

Managing diseases without heavy chemical interventions is a cornerstone of sustainable soybean production in Brazil. Biocontrol agents—beneficial microorganisms that suppress harmful pathogens—represent the fifth top innovation:

• Reduced crop loss: Antagonistic bacteria and fungi (like Bacillus subtilis and Trichoderma species) outcompete or neutralize disease-causing organisms, protecting root systems and plant health.
• Sustained yields: Consistent biological suppression can keep losses under 7%, a critical figure as more land is cultivated for soy and other commodities.
• Chemical reduction: By relying on biological treatments, farmers have been able to decrease their overall fungicide and pesticide applications, leading to improved soil health and ecosystem balance.
• Meets international food standards: Significant for exporter nations like Brazil, helping growers comply with global food safety standards.

Using biological disease management solutions thus plays a central part in both safeguarding crops and supporting higher yields per hectare.
