C5 Tundrabac®
C5 TundraBac mobilizes nutrients in the rhizosphere to improve fertilizer efficiency and support more uniform early growth. It activates in cool soils down to 8 °C, making it ideal for early planting in Canadian conditions.

C5 TundraBac®
C5 TundraBac is a microbial biostimulant based on the cold-tolerant bacterium Bacillus atrophaeus strain ABi05, designed to support young plant development by enhancing nutrient mobilization in the rhizosphere. Active at soil temperatures as low as 8 °C, it helps plants extract greater value from naturally present and applied nutrients, promoting more uniform early growth and vigor under cooler Canadian planting conditions.
Formulated as a concentrated liquid compatible with most fertilizers and crop protection products, C5 TundraBac integrates easily into early-season fertility programs. Its robust spores efficiently colonize the root zone, making it an ideal partner for early planting, better nutrient availability, and improved resilience against abiotic stresses.
