Advantage of PSB in Sorghum

18/03/2019Posted on
  • Increase micronutrients availability to plant from the soil like Mn, Mg, Fe, Mo, B, Zn and Cu in addition to P2O5.
  • Encourage faster root growth for water and nutrient uptake.
  • PSB produce organic acids like malic, succinic, fumaric, citric, tartaric acid and acetic acid which fasten the P2O5 uptake, maturity and increase yield.
  • Increase resistance towards diseases and drought tolerance due to rapid cell development in the plants.
  • Reduce 25 – 30% phosphatic fertilizer requirement.
