USK Zinc Solubilizing Bacteria (ZSB) 

• It is a biofertilizer containing effective strains of zinc solubilizing bacteria.
• It is used to mobilize soil fixed zinc and make it available to plants. 
• It secretes organic acids which solubilizes zinc in plant available form.
• It lowers pH of soil and helps in reclaiming alkaline soils. 
• It is eco friendly and compatible with other biofertilizers.
