Acid Sulfate Soil Restoration
By raising the water table, after damage has been inflicted due to over-intensive drainage, the soils can be restored. The following table gives an example.
Drainage and yield of Malaysian oil palm on acid sulfate soils (after Toh Peng Yin and Poon Yew Chin, 1982)
Yield in tons of fresh fruit per ha:
| Year | 60 | 61 | 62 | 63 | 64 | 65 | 66 | 67 | 68 | 69 | 70 | 71 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Yield | 17 | 14 | 15 | 12 | 8 | 2 | 4 | 8 | 14 | 19 | 18 | 19 |
Drainage depth and intensity were increased in 1962. The water table was raised again in 1966 to counter negative effects.

Famous quotes containing the words soil and/or restoration:
“I love, cherish, and respect women in my mind, in my heart, and in my soul. This love of women is the soil in which my life is rooted. It is the soil of our common life together. My life grows out of this soil. In any other soil, I would die. In whatever ways I am strong, I am strong because of the power and passion of this nurturant love.”
—Andrea Dworkin (b. 1946)
“In comparison to the French Revolution, the American Revolution has come to seem a parochial and rather dull event. This, despite the fact that the American Revolution was successful—realizing the purposes of the revolutionaries and establishing a durable political regime—while the French Revolution was a resounding failure, devouring its own children and leading to an imperial despotism, followed by an eventual restoration of the monarchy.”
—Irving Kristol (b. 1920)
