Tri-Start Mega is an inoculum of mycorrhizal fungi in pellet formulation with unique bacterial and fungal strains selected through Agriges’ intensive research activities at renowned research institutions. The last of these collaborations resulted in the Microbial production technology, which combines the activity of the unique siderophore bacterium Bacillus megaterium strain S3Nb3 with organic acids and micronised elemental sulphur. The result of this synergy is increased availability of nutrients to the crop, especially iron and phosphorus, and an important acidifying and desalinating activity of the soil. Applied as a normal basal fertilizer, Tri-Start Mega allows immediate colonization of the rhizosphere with useful microorganisms that stimulate root system growth, speed up plant establishment, overcome transplant stress, anticipate and improve uniformity of development.
