Question
Hi Jim got your email answer. Thanks. I've called Home Depot, Lowes, Mulch 1st and Oakland Nursery and no one has Dolomite Lime. The closest I've come to locally is from the nursery and it's called Hydrated Lime 2 lb for 5.99. Is this comparable to the Dolomite Lime?  I've checked online but the cost of the Lime is cheap but the shipping is double or triple the cost.                                 Thank you again.

Answer
They are not the same. Ground limestone is almost almost pure calcium carbonate and comprises the largest % of all lime used in the United States - it is abundant and the cheapest form of lime. Also, it is not caustic or disagreeable to handle like burnt or hydrated lime. It may also contain varying amounts of magnesium carbonate. Limestones containing significant amounts of magnesium carbonate are called dolomitic limestones. Dolomitic limestone contains about equal parts of magnesium and calcium carbonate. Hydrated/slaked lime ?
pound for pound is about 1-1/2 times more effective (at raising pH) and quicker to react than ground limestone (calcium carbonate). There are other forms of lime, but they're not generally something you'd want to use in a container. Home depot has it here under the name  Agricultural Lime. Might check for this as  Agricultural Lime.
