Garden Soil Testing and Repair for Acidic or Alkaline Soil

Gardening success or failure can be traced back to the garden soil.

How To Test Garden Soil

The only way a gardener can know what type of garden soil they have is by testing it. A piece of blue litmus paper (available at pharmacies) can be used to give a gardener a general idea if their garden soil is too acidic or contains too much alkaline.

To test garden soil using litmus paper, get several garden soil samples from various locations in your garden and mix the soil in a clean bucket. Pour clean rain water over the soil to make it muddy, place 3 strips of the litmus paper in the mud. Wait 10 seconds and remove a piece of litmus paper and rinse with clean water. If the blue litmus paper has turned pink, your garden has acidic soil, the brighter the pink, the more acidic the soil. Remove another piece of litmus paper after 5 minutes, and the last piece after 10 minutes. Rinse the litmus paper and compare the color to the first piece for confirmation.

For more precise garden soil testing, a soil test kit can be purchased from any garden supply center and range in price from a cheap, disposable soil test kit to more expensive and elaborate soil testing kits and meters.

If you don't want to test the garden soil yourself, contact your local county extension office and they will test your garden soil or tell you where to mail a garden soil sample too for testing.

How To Repair Acidic Garden Soil

Repairing acidic garden soil is simple, just add ground limestone. There are 2 types of ground limestone, calcitic and dolomitic, either type will work to neutralize the garden soil, but dolomitic contains magnesium which will fertilize your garden soil as well as neutralize the acid.

Limestone should be added to garden soil at the rate of 5 pounds per 100 square feet and tilled into the soil. Wait 2 weeks before planting any vegetable or flower seeds, and don't add fertilizer to the soil for 2 weeks after adding ground limestone.

Adding hardwood ashes from a wood burning stove or fireplace and tilling it into your garden soil will keep garden soil from becoming too acidic.

How To Repair Alkaline Garden Soil.

Repair alkaline garden soil with sulfur or borax, and a little bit of either will go a long way. Too much sulfur or borax will kill garden plants and flowers, so use sparingly. Apply 2 pounds of ammonia sulfate or borax per 100 square feet of garden. Till it into the garden soil and allow to sit for at least 2 weeks before doing any garden planting.

Adding organic matter, specifically oak leaves, oak saw dust or oak tree bark will repair alkaline soil and won't harm your garden plants. Gypsum will also repair alkaline garden soil and improve soil drainage.
