Expert Answer:

  • Most of the plants grow best when p H of the soil is close to 7.
  • The p H of the soil can reach as low as 4 and that of the basic soil can go up to 8.3.
  • If the soil is too acidic, then it is treated with quicklime (calcium oxide) or slaked lime (calcium hydroxide) or chalk (calcium carbonate).
  • If the soil is too alkaline then its alkanity is reduced by adding decaying organic matter which contains acidic materials.
