Nitrofix (SR)

Biological stimulation mechanism: the efficacy of Nitrofix (SR) powder

The product is a concentrated inoculant based on highly efficient strains of nitrogen-fixing bacteria Bradyrhizobium japonicum. Unlike liquid formulations, the powder form ensures high stability of the bacterial population during storage and transport. The manufacturers, Calister S.A. (Uruguay) and Bionaservice Plus (Ukraine), have focused on creating an environment that maintains microorganism viability until the moment of contact with the seed.

Technical insight: how the product works on the seed

• Adhesion and colonization: When applying the powder to soybean seeds, it creates a thin protective film where bacteria transition into an active phase upon soil moisture absorption. This ensures tight attachment of colonies to the root embryo.
• Symbiotic fixation: The product initiates early nodule formation on the root system. Technically, this facilitates the conversion of atmospheric nitrogen into ammonia, a form readily available for plant uptake.
• Metabolic efficiency: Integrating this product into pre-sowing preparation allows the plant to conserve internal resources, redirecting energy from nutrient foraging toward vegetative mass development and bean pod formation.

Using this preparation minimizes germination stress. Classified under hazard class 4 (low-risk substances), the technology is suitable for both organic and intensive farming without strict limitations on protective equipment. The practical result is a clear increase in crop yield through optimized nutrient supply during early vegetative stages.
