Plant microbial biostimulant that improves potassium assimilation and potassium balance in the soil, and increases resistance to droughts and frost.
Bacto-K is a plant microbial biostimulant built on Bacillus megaterium MVY-011, a potassium-mobilising bacterium. It improves potassium assimilation and the potassium balance of the soil — the nutrient behind water regulation, standing power and stress tolerance — helping crops resist drought and frost.
FiBL registered and approved for organic farming, it is applied to the soil from before sowing until canopy closure at 1–5 L/ha depending on the crop.
