How to Lower Alkaline Soil Levels

Sphagnum Peat

• 1

  Take a sample of your soil to your local county extension office. Have them test your soil's pH level.

• 2

  Obtain a supply of sphagnum peat if the test shows that your soil is too alkaline.

• 3

  Spread 1 to 2 inches of sphagnum peat on your soil. Work it into the top 8 to 12 inches of soil with a hoe.

Iron Sulfate

• 4

  Give a soil sample to your county extension and have them test it. Obtain a supply of iron sulfate if soil tests high for alkalinity.

• 5

  Spread it on the soil with a spreader. Use 4.8 lb. of iron sulfate per 100 square feet if you have sandy soil. Use 19.8 lb. per 100 square feet if you have loamy soil.

• 6

  Avoid applying more than 7 lb. per 100 square feet at any one time. Place applications of 7 lb. one to two months apart for best results. Water frequently between applications.
