Adding Agriculture Lime to Garden Soils

Posted September 01, 2015

Adding lime to your soil may or may not be a good idea ~

Dolomite Agriculture Lime is a powder which contains calcium, magnesium and is commonly used to raises low soil pH levels.

It is best to determine your soils pH before applying Agriculture Lime to any soil. 

If your soil is acidic (low pH), deficient in calcium and magnesium, liming soil is especially important for plant nutrients. Generally soils that do have a low pH, are low in these nutrients.  When using lime, don't overdo!  Over use of calcium and magnesium makes the soil incapable of holding other nutrients and may take years to correct.  More is not better!  The amount of lime being used will depend on the amount of clay in the soil.  We recommend using no more than 8 pounds of Dolomite lime for acidic clay soils and 5 pounds of lime in acidic sandy soils per 100 square foot based on soil pH of 5.0 to 6.0.  In general, sandy soils will need less limestone to change pH and clay soils will need more.  Fall is a good time to apply Dolomite Lime into the soil.  This gives it time to dissolve and become available for spring plantings.  Till or dig planting area to the depth of 12 inches and spread lime over the prepared surface working it in the top 2-3 inches with a rake.

Liming soils that already have a high pH, is it not a good idea to lime the soil.  Liming will only increase the soil pH levels, making it difficult for plants to uptake needed nutrients.
