Why Brazil needs a new source of Biostimulants

Brazil’s agricultural sector is one of the largest in the world, producing millions of tons of soy, corn, and cotton annually. These crops require inputs that improve growth, resilience, and yield without harming the environment. Biostimulants have become essential tools in this effort. Traditionally, Brazilian farmers have relied on brown seaweed extracts imported from the North Atlantic. While effective, this supply chain is costly and vulnerable to disruptions.

This post explores how Brazil’s red seaweed could transform biostimulants, the challenges of scaling production, and the vital role of collaboration between research institutions and industry players.

The reliance on imported seaweed also raises sustainability concerns. Harvesting brown seaweed in the North Atlantic can impact marine ecosystems, and the long-distance transport adds to the carbon footprint. Brazil’s vast coastline and tropical climate offer an opportunity to produce bioinputs locally, reducing costs and environmental impact.Brazil is on the verge of a significant shift in agricultural bioinputs. For years, the biostimulants market has depended heavily on imported brown seaweed, Ascophyllum nodosum, sourced from the North Atlantic. Now, a new contender is emerging from Brazil’s own tropical waters: red seaweed, specifically Kappaphycus alvarezii. This locally sourced seaweed offers a promising alternative that could reshape sustainable farming practices across the country’s vast commodity farms, including soy, corn, and cotton.

Red seaweed thriving in Brazilian coastal waters

The Promise of Kappaphycus alvarezii Red Seaweed

Kappaphycus alvarezii is a tropical red seaweed widely cultivated in Southeast Asia for carrageenan production. Its fast growth rate and adaptability to warm waters make it an ideal candidate for Brazilian coastal farms. Beyond carrageenan, this seaweed contains bioactive compounds that can stimulate plant growth, improve nutrient uptake, and boost stress tolerance.

Early research and pilot projects in Brazil have shown promising results:

• Increased root development and nutrient absorption in soy and corn crops

• Improved resistance to drought and pests

• Enhanced soil microbiome activity, supporting long-term soil health

  
  

These benefits suggest that red seaweed extracts could match or even surpass the performance of imported brown seaweed products.

Scaling Up Production for Brazil’s Commodity Farms

Brazil’s commodity farms operate on a massive scale, so any new bioinput must be produced in large volumes and at competitive prices.

Multi-season field trials are essential to demonstrate consistent benefits and return on investment (ROI) for farmers. These trials must cover different crops, soil types, and climatic conditions to build confidence in the new bioinput.

Collaboration Between Research and Industry

The success of Brazil’s red seaweed biostimulant depends on strong partnerships. Research institutions like EPAGRI (Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina) play a crucial role in conducting field trials, analyzing data, and developing best practices. Their expertise helps validate the effectiveness of red seaweed extracts and optimize application methods.

At the same time, industry players bring experience in cultivation, processing, and distribution. By working together, researchers and companies can accelerate product development, reduce costs, and expand market reach.

Brazil’s move toward red seaweed biostimulants represents a practical step toward more sustainable agriculture. By harnessing a native resource, the country can reduce costs, support local economies, and improve crop resilience. The path forward requires careful research, collaboration, and clear communication to farmers.
