Asked by raoss1967 | 06 May, 2015, 12:09: PM
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.
