Dolomite lime 10 AG is Ca 46% - Mg 28%
Dolomite Lime is an all natural pH Adjuster that is very high in pH, Magnesium, and Calcium. Magnesium and Calcium are essential secondary nutrients required for plant growth and if the soil is acidic Dolomite Lime may be added to adjust the pH.
Dolomite Lime is not usually the best choice for valley floor soils, but rather for the hills around the valley, due to its high level of magnesium. The magnesium tends to be out of balance with the Calcium in this valley. An optimum CA to Mg ratio would be 7-1 CA to Mg, and in the Willamette Valley, it's the opposite in most cases. So adding Mg is a formula for making clay soils even more sticky and hard.
Use a lawn and garden lime, like Garden Pearls Lime if you are on the valley floor. General use rate is 1-10 lbs per 100 sq ft.
A soil pH test is the best way to find out if you need lime.
