Rovensa Next Launches New Inoculant for Maximizing Nutrient Efficiency in Brazil

By Rovensa Next|9 March 2026

Rovensa Next, a global leader in biosolutions for agriculture, announces the Brazilian launch of Otimais Duo, an advanced dual-microbial inoculant designed to maximize nutrient-use efficiency root development and deliver consistent productivity gains in the field. Otimais Duo marks a significant milestone for the company, reinforcing its breakthrough Biosolutionize Agriculture movement and its call to reshape global farming through powerful, profitable, science-driven biosolutions.

A dual-microbial technology engineered for performance

“As growers seek greater efficiency from every input, biological solutions are becoming central to modern crop nutrition. Otimais Duo has been developed within this context as a science-based tool designed to enhance the performance of conventional fertilization programs,” said Victor Sonzogno, Head of Brazil at Rovensa Next.

At its core is a carefully selected combination of two microbial strains: Azospirillum brasilense Ab-V5, which fixes biologically atmospheric nitrogen, and Pseudomonas fluorescens BR14810, which solubilizes phosphorus and promotes plant growth through phytohormone production.

These microorganisms act in synergy to stimulate key enzymatic pathways such as acid phosphatase and nitrate reductase, thereby increasing nutrient availability and their uptake by plants. The result is stronger root development, improved vegetative growth and greater crop resilience.

Otimais Duo is set to become a cornerstone for modern biosolution strategies, helping growers boost crop performance while using fewer mineral fertilizers. Its dual‑microbial technology, combining Azospirillum brasilense and Pseudomonas fluorescens, improves nitrogen and phosphorus uptake, unlocking greater value from every input. Otimais Duo integrates seamlessly into conventional fertilization programs. It enhances root and shoot development, increases yields, and supports long-term soil health, making it an essential tool for sustainable, high-efficiency crop management.

Field-proven efficacy across geographies and crops

The launch is supported by a robust body of field data. Otimais Duo consistently demonstrated significant productivity improvements and enhanced nutrient-use efficiency across 94 trials conducted on 10 key crops in seven countries.

In maize, 58 trials recorded an average yield increase of 1,302 kg per hectare, with gains reaching up to 3,210 kg per hectare in specific locations. Seed treatments delivered average increases of 1,344 kg per hectare, while foliar applications achieved 1,596 kg per hectare.

Soybean trials showed equally consistent performance, with 39 trials delivering an average increase of 600 kg per hectare across all tested application methods.

Importantly, the best performance was observed when Otimais Duo was combined with mineral fertilizers in an integrated biosolution strategy, confirming that Otimais Duo acts as an efficiency enhancer, optimizing nutrient dynamics and improving plant assimilation rather than compensating for nutrient reductions. These results position Otimais Duo as one of the most technically robust and efficacy-proven biosolutions in Rovensa Next’s portfolio.

Advancing the Biosolutionize Agriculture movement

Otimais Duo embodies the ambition of the Biosolutionize Agriculture awareness campaign, which is to make farming more efficient, more profitable, more sustainable, and more resilient.

The product increases the return on every unit of fertilizer applied by improving nitrogen and phosphorus assimilation. Its repeatable yield gains across diverse geographies translate directly into improved grower profitability. In addition, enhanced microbial activity and reduced nutrient losses contribute to healthier soils and lower environmental impact. Stronger root architecture and improved nutrient balance also help crops better withstand climate and soil stress, reinforcing agricultural resilience in an increasingly unpredictable environment.

Otimais Duo, as a biological solution rooted in advanced microbial science, strengthens Rovensa Next’s ambition to lead the global biosolutions market where innovation meets sustainability and grower performance.
