Inoculation and nutrients in the planting furrow require attention.

When selecting products for application in agriculture, it is essential to consider not only the type of input, but also its compatibility with biologicals and inoculants. This attention is increasingly important given the wide range of solutions available on the market, which require producers to be careful to ensure the safety and effectiveness of the mixtures.

One example is boron, a micronutrient essential for plant development. Various sources of this element are available, and both the raw material and the final product can vary between manufacturers. These differences can directly affect the effectiveness of inoculants and biological products if applied together without compatibility studies, potentially leading to undesirable physical or chemical reactions.

Important care

In soils with low boron content, a common practice is to provide part of the recommended dose along with inoculants and biological products in the planting furrow. This is possible, but requires care regarding the source used and its compatibility. Otherwise, the result may be compromised. Agronomist Alécio Fernando Radons, technical sales manager for Satis in Rio Grande do Sul, explains that there is no inherent incompatibility between boron and... Bradyrhizobium - a bacterium that plays a crucial role in BNF - under normal field conditions, as boron is essential for both plant growth and biological nitrogen fixation (BNF).

“The problem arises in situations of toxicity due to excess or physicochemical incompatibility in direct mixtures, which can impair the formation of nodules on the roots and, consequently, the efficiency of biological nitrogen fixation (BNF) in crops such as soybeans,” he points out. He recommends that producers strictly follow the manufacturers' guidelines and verify if there are technical studies that prove the safety of the mixtures. “Not every product is the same, even if it contains the same nutrient in its composition. Compatibility is fundamental to avoid losses in efficiency and guarantee the best result,” Radons emphasizes.

Demand for nitrogen

He cites the example of soybeans, which have a high demand for nitrogen and depend heavily on biological fixation. Therefore, good inoculation with [various ingredients] is essential.

Recognized for its continuous investment in research and innovation, the Minas Gerais-based company Satis developed Humicbor, a soluble boron source enriched with humic substances, algae extract, and polyols. The product has a technical report from the Federal University of Tocantins (UFT), which demonstrated that the addition of boron did not interfere with the growth of the strain of...

With the advancement of biological technologies in the field, the need for caution in choosing and combining inputs is also growing. Opting for products with scientific evidence and guaranteed quality is the best way for those seeking productivity and sustainability in farming.
