The availability of P2O5 is maximum at
Answer & Solution
Correct Answer:
Option
C
The availability of P2O5 is maximum at Neutral.
Phosphorus pentoxide is a chemical compound with the molecular formula P2O5. This white crystalline solid is the anhydride of phosphoric acid. It is a powerful desiccant and dehydrating agent.
The soil pH for optimum phosphorus availability is 6.5.
At high or neutral pH, phosphate reacts with calcium to form minerals, such as apatite.
At low pH, under acidic conditions, phosphorus may react with aluminum and iron to form minerals, such as strengite and varescite.
